Power Commander Installation Issues

How to install software from CD
If you are having a problem installing software from our CD, you can run the installs manually. If you explore the CD, go to the directory FSCOMMAND. In that directory are two files to run for setting up our software. PC3setup.exe is the install for the Power Commander III USB. PCVSetup5*.exe is the install for the Power Commander V.

Answer

Powering up the PCIIIUSB
The Power Commander needs to be constantly powered in order to communicate fully with the computer. It should have a constant green light on. Make sure you have a fresh (above 8.5 volts) 9 volt battery if using the battery adapter; or if using the bikes power, most bikes need to be running to provide the constant power needed rather than just turning on the key. Make sure the USB connector is fully seated into the Power Commander. If there is any silver showing on the connector, it is not completely plugged in. It is a tight snap-in fit connection.

Answer

Jumping TPS
A common problem we have seen on bikes is jumping TPS. Many older Power Commanders had a Gray wire to tap into the variable voltage wire of the bikes TPS. This type of connection is prone to having this problem. The newer Power Commanders often have a plug in connection for TPS; this type of connection solves the jumping TPS problem.

If you have the older style wire harness, a fix for this problem is grounding the digital ground wire to the TPS, instead of battery or chassis ground. In the Power Commander wiring harness should be two wires connected to ground. These wires are Black, and Black with White trace. Separate these two wires; and leave the Black wire at normal ground location. Take the Black/White wire and reroute it to the TPS sensor ground. There should be three factory wires going to the TPS sensor; ground, constant 5 volts, and variable volts. The Gray wire from the Power Commander should be connected to the variable volt wire. Just connect the Power Commander Black/White wire to the ground wire of the TPS. That should cure the jumping TPS problem. Power Commander Installation Issues

Answer

Power Commander V on older bikes
The PC V was initially released for 09 models forward only. We have started offering the PCV for some models older than 09. We have not tested and verified operation of the unit on some of the older models at this point, so we cannot officially support it for use on anything other than what we have tested. Some of our dealers and individuals as well have successfully retro fitted the PC V to older model bikes that have not changed from previous model years to 09. Since we have not done any testing on the older models we do not have any pre developed maps for many model years prior to 09 either. A map for a Power Commander IIIUSB can be imported to the PCV. Any installation and utilization other than those applications specifically recommended by Dynojet would be at your own risk. Power Commander Installation Issues

Answer

Power Commander EX
The Power Commander EX is a unit that was developed for those areas of the country that have more stringent emission regulations, i.e. California. Those areas do not allow devices that change the fuel curve in certain areas on pollution controlled vehicles legally driven on the street. Therefore the EX unit does not allow for fuel changes to be made in a substantial area (lower RPM and throttle positions) of the fuel map in order to gain legal status in those places. This area is grayed out in the fuel map. The race ready Power Commander line allows for fuel changes to be made in the entire map as well as offering several more features which are omitted from the EX units. The Race Ready unit is differentiated from the EX street approved unit, in that it can make a substantial difference in power and performance, as well as providing a cooler running motor. We do not specifically recommend one unit or the other, but leave that up to the individual customer to determine which unit best fits their needs and local regulations prior to purchase.

Answer

Does a Power Commander make my vehicle faster?
The Power Commander is a tuning tool to adjust fuel, and on some models ignition timing. Just adding a Power Commander to a completely stock vehicle usually does not increase peak horsepower. It usually will improve drivability, throttle response, and mid-range horsepower and torque. If the vehicle has been modified in some way to increase airflow through the motor, the Power Commander can provide the correct amount of fuel for those modifications. This will often give an increase in overall horsepower. Power Commander Installation Issues

Answer

Do I need to disconnect my o2 sensors?
In order for the race ready line of Power Commanders to have complete control over everywhere a vehicle runs, we usually want to disable, or control the stock o2 sensor(s) on a machine. This gives us the ability to tune the vehicle everywhere. If the stock o2 sensors are left connected as from the factory, they would conflict with the fuel changes the Power Commander is making. In effect, nullifying the fuel changes the Power Commander makes. Power Commander Installation Issues

Answer

Will this Power Commander fit my bike?
Dynojet makes about 500 different Power Commanders; they are pretty much unique to a certain year/model vehicle. A Power Commander for one vehicle, most likely will NOT work on a different vehicle. There are exceptions to this rule; a similar model from the same manufacturer might use the same Power Commander. If you have any questions, just give us a call or email for fitment questions. Power Commander Installation Issues

Answer

Why doesn’t your AutoTune use 10/12mm o2 sensors?
Dynojet supplies industry standard Bosch 18mm wideband o2 sensors in our AutoTune kits. 10/12mm wideband o2 sensors are not readily available. To use the AutoTune module, 18mm bungs need to be welded into the headpipes and the 18mm sensors need to be inserted into these bungs. Dynojet has tested a few of the 10/12mm to 18mm adapters and found them to not work correctly. Power Commander Installation Issues

Answer

Do you have software that runs on Android, tablet, Mac?
No, at this time Dynojet has not developed software for any other computer operating system than Microsoft Windows. Every version of Windows since 95 SP2 will run all of our current software. Power Commander Installation Issues

Answer

Does the Power Commander V have built in Ignition control?
We do offer “built-in” ignition timing adjustability and ignition controlled features (Rev X-tend, Launch control, Pit-lane Speed Limiter, etc.) on the Power Commander V module for a select few single and twin cylinder models. Three and four cylinder models would require an additional Ignition Module accessory for this capability, if available. Power Commander Installation Issues

Quick Shifter problems
There are two simple tests you can do to test the Quick Shifter function. First with an ohm meter, disconnect the QS, and connect the ohm meter to each wire from the QS. Sit on the bike and make an up shift with your foot. You should see the continuity change on the meter, and then change back when you release the shifter. This tests the sensor and the installation.

The Second test is the static configuration test. With everything connected normally, go into the Power Commander software QS setting and lower the minimum RPM to 1000, and change the kill time to 250. Send map. Now sitting still with the bike running in neutral, pull in the clutch and move the shifter into second with your foot. The motor should stall. If it does the QS is working correctly. Change the settings back that were changed above. Power Commander Installation Issues

Answer

LCD-200 Setup
The LCD is not setup to display any data by default; it has to be configured first. To setup the LCD unit, the vehicle has to be running. First go into Gage Setup. Next select the layout you prefer. Next, select Edit for each gage in turn. Next select Edit next to Channel. Next, click on the Device you want to get the data from, and then click on the Channel of that device you want to display. Now click on Select, and then exit back to Gage setup. Now just repeat the above steps for each of the gages you want to display. Power Commander Accessory Issues

Answer

Terminator Plug
The Power Commander V communicates with other Dynojet products (AutoTune, SFM, Ignition modules) via a CAN cable. These devices can be daisy chained one after another; the last device in the chain has to have a Terminator Plug installed to end that chain of devices. These devices will not communicate to the Power Commander unless the Terminator Plug is installed in the last device. Our LCD-200 has a built in terminator plug, so it can be used as the last device in a chain; the units preceding it in the chain would not need a Terminator Plug. Power Commander Accessory Issues

Answer

LCD screen calibration
At times the LCD loses its calibration, and the touch screen will not respond. This can be corrected by doing a touch panel calibration. This can be accomplished using the three Red buttons. If the screen is oriented with buttons on the right, the buttons do the following:
The top button is Escape.
The middle button is a Joystick. This button moves up & down, and left & right.
The bottom button is Accept.
Use the middle button to highlight the selection you would like, and then use the bottom button to accept that selection.

From the main menu, go to LCD Config, Touch Panel, Start. Then touch the five bull’s-eyes in sequence. You may want to use something Power Commander Accessory Issues

Answer

Update LCD firmware
The LCD is controlled by the firmware version that is loaded. There are two versions of firmware available on the website, LCD-100 and LCD-200. Either version of firmware can be loaded on any LCD module, in effect changing an LCD -100 to a LCD-200, or vice-versa. To install firmware you need to use the Dynojet Display File Manager software. Open this software, and plug the USB cable into the LCD while holding down all three Red buttons. If you do this correctly, the LCD will show a Bootloader screen. Now you are ready to run the firmware update. In the Display File Manager software select Actions, Update Firmware. Select the firmware file you want to load and click Open. The firmware update will run and complete the update. Power Commander Accessory Issues

Answer

PCV Map Switch
The Power Commander V is capable of having two maps loaded, and being able to switch between them on the fly. Once you have made the physical connections of the map switch, you need to enable the option in the software, and then send a second map to the Power Commander. In the desktop software this option is found under Power Commander Tools/Configure/Feature Enables & Input Selections. Check the box next to Map Switch; click Ok, and then Send Map. After enabling this option, the first time you send a map to the Power Commander, you should get prompted on which position to send the map to. Once you have sent two maps to the Power Commander, every time you Send or Get Map, it will perform that function on the map that is selected. Power Commander Accessory Issues

Answer

How often to accept AutoTune trims?
The AutoTune module creates the adjustments and stores them in a table called Trim. It is a good practice to accept these trims a few times (2-3), on a new install. When you accept the trims you will be moving the values generated by the AutoTune from the trim table(s), to the fuel table(s). This feature can be found under Map Tools/Auto Tune tables/Accept All Trims. Be sure to Send Map after accepting the trims. After accepting the trims a few times, there is little benefit to continue accepting the trim values further; the AutoTune will always make small day to day adjustments. Power Commander Accessory Issues

Answer

How do I add a SFM or Ignition module to my PCV?
The Power Commander controls the secondary units SFM or Ignition modules. In order for the Power Commander to do that, it has to know the other unit has been added. To accomplish this, just plug both the PCV and other unit into the computer using two USB cables. The Power Commander software should detect a second device, and prompt you to add it to the network. Once a second device is added to the network, the Power Commander software will want to see that second device from then on. You will need to use two USB cables, or run the engine to accomplish this. Power Commander Accessory Issues

Answer

Should I buy the AT-200 or AT-300 AutoTune?
If you have a 2 cylinder bike with a PCV, you have a choice to use either the dual channel kit (AT-300) or the single channel kit (AT-200). The dual-channel AutoTune kit tunes more accurately (cylinder advanced), but is more expensive. Some people don’t feel the gains outweigh the cost, but others do. The gains to be made with dual channel over single channel are dependent on the bike model. On an air cooled V-twin, the cylinders are going to need different fuel quantities because of the cooling differences. A parallel or boxer twin would have very similar cylinder temps, and have similar fuel requirements. There is also exhaust airflow differences to consider, a V-Twin has very different flow from cylinder to cylinder; other types of twins have nearly identical exhaust flow from cylinder to cylinder. It’s a judgment call which is best for your bike. Power Commander Accessory Issues

Answer

How do I tell if my AutoTune is working?
The easiest way to determine if the AutoTune is working is to go for a ride, come back, plug the Power Commander into a computer and look at the trim table(s). If there are values in any cell other than zero, AutoTune is working. If the table is all zeros, AutoTune is NOT working.

Answer

What does the start-up fuel option do?
This option gives you the ability to add, or remove fuel for a short period of time during engine cranking and initial start-up. This option is commonly used on with big motor builds, to get the bike to start when cold. It can also be used to remove excess fuel during start-up when larger injectors are installed. Power Commander Accessory Issues

Answer

Should I purchase the AutoTune module, or have my vehicle custom tuned on a dyno?
The AutoTune module does give an end user the accessibility and capability to custom tune a Power Commander map file, as accurately as a professional dyno tuner using the Bosch LSU 4.2, 5-wire, wideband O2 sensors for exhaust gas analyzation. Some users may find that having a professional tuner setup everything as needed (including the AutoTune feature) is necessary. As a professional tuner is only as good as the equipment he/she uses, the equipment is only as good as the person using it also. Power Commander Accessory Issues

Answer

My Launch Control option is not working, how can I test it?
First, the Power Commander has to be in control of Ignition timing to use this feature. The Power Commander is basically looking for a change of continuity to ground on a wire when the clutch lever is moved. Basically the wire would be grounded, and then not grounded when the clutch lever is pulled, or vice versa. Test this wire with a multi-meter, engine running, side-stand up, and in gear. We have seen various bikes act differently under all of these conditions. Power Commander Accessory Issues

Answer

Quick shifter configuration in PCV
When setting up a Quick Shifter with a Power Commander V, there are a few things to keep in mind.
  • If the bike has 8 fuel injectors, just the Power Commander is not enough; you will also need an Ignition module, SFM, or QEM.
  • You can only use gear dependant mode it you have ran a wire from the bikes speed or gear sensor to the Power Commander V, and have configured speed or gear input. In most cases start out with Single Time mode.
  • Make sure the settings for switch style is set to match the sensor you actually have. Dynojet has sold both types, open or closed. The best way to confirm your sensor type is with an Ohmmeter. At rest, the sensor will either have full continuity (closed), or no continuity (open). Set the switch style to match your sensor.

Answer

How do I configure AutoTune target AFR?
Dynojet creates target AFR tables for most of our pre-configured maps. The values in our supplied AFR table are what we recommend for most users. You are free to change these values to meet your needs or desires. The AFR values we supply are what we have found to work best on that particular vehicle. There are some older maps that do not have any values in the AFR table; you will have to fill those in yourself. Most naturally aspirated four stroke engines, running pump gasoline, make the best horsepower at an AFR between 12.8 – 13.4; and get the best fuel economy around 14.7 AFR. Boosted engines need significantly different numbers. Power Commander Accessory Issues

Answer

How do I configure Accel Pump in the PCV?
The Power Commander V has a feature called Accel Pump. This gives you the ability to add, or remove fuel for a short time when the throttle is moved quickly. The three options need to be configured to accomplish what you want to achieve.
  • Trigger is the amount of throttle movement. A value of 20 means if the throttle is quickly moved 20 percent or more, the Accel Pump is activated.
  • Duration is the length of time the Accel Pump would be active. For example a value of 83 would give about one second of fuel at 5000 rpm, and two seconds of fuel at 2500 rpm.
Fuel Adjustment is the percent of fuel to add, or remove. Positive numbers add fuel, negative numbers remove fuel Power Commander Accessory Issues

Answer

How do I configure Quick Shifter settings?
The Quick Shifter has settings that can be adjusted for longer or shorter kill times; and the minimum rpm the Quick Shifter will function. You may find the default settings work for you, or you can make adjustments. You can adjust the kill time longer or shorter; the engine will hesitate for that number of milliseconds. You can set the minimum RPM to whatever you like; the Quick Shifter will only work above that RPM. You can only use gear dependant mode if you run a wire from the bikes speed/gear sensor, and configure speed/gear input. Power Commander Accessory Issues

Answer

Can I have AutoTune start working after a certain engine temperature?
The AutoTune process has an option to start working only after a certain engine temp is reached. In order to use this option, the Power Commander V has to be connected to the engine temp sensor, and temp input has to be enabled on the PCV. Power Commander Accessory Issues

Answer

Software Issues and Features

Setting throttle position
We have seen as high as an 8% variation in the throttle position from bike to bike. If yours is not reading “zero” at idle with the motor at normal temperature, then use the following procedure to correct it. In the Power Commander Control Center Software, go to menu “Power Commander Tools” and look for the tool to calibrate the throttle. The bike should always be running when setting the throttle position, as the voltage the sensor sends out can vary between when the bike is at “key on” and “motor running”. The bike also needs to be at fully warmed up to its normal operating temperature. All you need to do is press "reset" while the bike running at idle, then quickly turn the throttle wide open till you hit the mechanical stop, then let go. Next press "Ok". You don't have to rev the bike out, the throttle just needs to go all the way to wide open and then back to idle. Autotune

Answer

Power Commander III Button adjustment
With the ignition off, hold down all three buttons on the Power Commander III unit. While still holding down the buttons, turn on the ignition and start the bike. Release buttons. The light(s) should show up in the last place they were left, by default the center two lights. Select the range you wish to adjust: Low, Med, High by pushing the corresponding button once, (these ranges are determined by taking the bikes RPM limit and then dividing it into thirds). At this point holding that button down will move the lights down (leaning out the mixture). Pushing the button repeatedly will move the light up (richening the mixture). When the two center lights are lit up this is the “0” setting. After making your adjustments wait 20 seconds before turning it off. This allows the settings to be saved to memory. Autotune

Answer

AutoTune Running Light
The AutoTune running light in the software will only come on if all of the parameters for the AutoTune to work are true.
  • The light on the AutoTune module is steady Red.
  • The Can cable and Terminator plug are installed.
  • The require run time, if enabled, has elapsed.
  • The require engine temp, if enabled, has been exceeded.
  • AutoTune Switch, if turned on, switch is in the correct position.
  • The motor is running at an RPM and Throttle position that has a valid number in the target AFR table.
  • The live AFR reading is between 11.5 and 16.0. If all of these parameters are met, the light for AutoTune Running should be lit.

How do I downgrade my map from advanced to basic?
On the Power Commander IIIUSB, just go to Tools, Demote map to Basic. With the Power Commander V, this setting is found under Map Tools, Advance Demote map, Fuel Tables (TPS). Change to Basic. If Basic is not an option, you will need to Delete AutoTune tables first. To do this go to Map Tools, AutoTune tables, Delete tables. Once this is done, the option to change to Basic fuel tables should be available. Software Issues and Features

Answer

Can I use two maps and AutoTune at the same time?
The Power Commander V does have the capability to store 2 maps in its memory that can be toggled “on the fly” with any simple single pole, single throw switch wired to 1 of the 2 available switch inputs on top of the PCV module. The extra memory capacity for the 2nd map is also what is used to store Auto-tune tables, so the Map Switch feature and Auto-tune feature can NOT be enabled simultaneously. If Auto-tune is enabled, you could instead use the switch to toggle the Auto-tune feature on/off “on the fly.” Software Issues and Features

Answer

Reset a PCIIIUSB
To reset the Power Commander, connect it to the software and power it up using the 9-volt adapter. Once you have communication established go to the "Tools" menu and select "Environmental Options". Once you have selected that option a window will appear that has a black rectangular button at the bottom that reads "Reset Power Commander". If the button is not visible then you would have to hit the "Control" and "R" keys at the same time on the computer keyboard to display it. If you are using a custom map or one that has been altered, make sure you save a copy of your map first, as the reset procedure will zero out the map and reset the power commander to the factory default settings.

Rev Extend in predeveloped maps
The reference in the map notes about the Rev Extend enabled indicates that that map was developed with the Rev Extend enabled and the fuel was mapped though the higher rpm settings. It does not indicate that the Rev Extend feature is turned on in your Power Commander. You must still manually turn on the feature in your Power Commander in order for it to rev to the higher limits Software Issues and Features

Answer

Firmware updates
The Power Commander is controlled by firmware in the unit. This firmware can be updated in the field by running a firmware update. The latest firmware is always available on our website. Firmware updates are how Dynojet introduces new features, and fixes known problems. A firmware update is not required unless you are having a problem, or want to take advantage of newer features. You have to be using the latest desktop software to install the latest firmware. Just download and save the latest firmware, and then unzip the file someplace you can find quickly on your computer, like the desktop. Next, run the update firmware from within the Power Commander desktop software. The update will take a few minutes to run; when complete your firmware should be up to date. The Power Commander V firmware update often needs to be run a few times to complete fully. The Power Commander III USB needs the 9 volt adapter to perform a firmware update. Software Issues and Features

Answer

Update firmware
The Power Commander V, SFM, and PCV Ignition module all take the same version of firmware, and all modules on one vehicle need to have the same version. The Power Commander III USB and Ignition module have different versions of firmware available, and they need to have compatible versions. If you update your Ignition module, you may also need to update your Power Commander. Be sure you select the correct firmware for your device. The Power Commander III USB needs the 9 volt adapter to do a firmware update. The Ignition module needs the Programmer module and 9 volt adapter. The latest firmware is freely available on our webpage. Software Issues and Features

Answer

Loading a map
The map in a Power Commander controls how the vehicle runs. The correct map should make the engine run well; the wrong map may cause the engine to run poorly. To load a map in a Power Commander, you need to have installed the correct Power Commander Software and maps. Both of these are freely available on our website. First open the software, and then select Open Map. Select a map you want to use, then Send Map to overwrite the current map with the one you have selected. The Power Commander III USB needs power to complete this; either the 9-volt adapter or by running the engine. The Power Commander V only needs the USB cable to do this. Software Issues and Features

Answer

How do I use the Switch Input under feature selections on the PCV?
You have two options for switch input, 1 or 2. These relate to the holes on the side of the Power Commander. Starting at the outside edge at 1, and counting inward, holes 6 and 7 are switch input 1. Holes 4 and 5, are switch input 2. If the wires from your Map switch or Quick Shifter are connected to the holes 6 and 7, set the option to switch input 1. If they are connected to holes 4 and 5, set the option to switch input 2. Software Issues and Features

Answer

Setting throttle position on fly-by-wire bikes.
The normal procedure to set the throttle position will not work correctly on fly-by-wire bikes, because the throttle is controlled by the bike’s ECM. The throttle blades may not go fully open until the engine is actually above a certain RPM, or some other parameter is met. In these cases, you only need to adjust the closed value so TPS reads zero at normal idle. In the throttle calibration screen, there is an arrow button pointing to the left. If you click this button, the numbers in the left box will be changed to match those in the center. Click Ok, you should see the TPS is now reading zero. Software Issues and Features

Answer

Do I need to use Get/Send Map or Table on the PCV?
The Power Commander V software offers the option of getting or sending a table, vs. getting or sending a map. A map for a Power Commander can be made up of multiple tables. If you are looking at one table, and select Get or Send Table, you are only doing that one table. If you select Get or Send Map, you are doing all the tables. Software Issues and Features

How do I adjust gear calibration?
The Power Commander V has a utility to accept speed input, and then the unit will be able to calculate what gear you are currently in, based on that speed input. Connect the factory gear sensor to Analog input on the PCV. To calibrate this, put the bike on a stand with the rear wheel able to spin freely, start the motor. In the PCV software go to Power Commander Tools > Calibrate > Gear position. Put the bike in first gear, and let the rear wheel spin while the bike idles. Click the Calibrate button for gear 1. Next, shift the bike into each higher gear, and repeat the process, clicking on the Calibrate button for that gear. If the bike is moving with the clutch out, the Power Commander will now know what gear the bike is in. Software Issues and Features

Answer

How do I calibrate speed input on a PCV?

Tuning Issues

Deceleration popping in the exhaust
Decel popping is caused by the detonation of unburned fuel in the exhaust pipe. This happens with high flow exhausts that allow more fresh air to be pulled into the pipe, causing the exhaust temperature to rise and detonate any unburnt fuel. Ways to reduce and possibly eliminate this popping are listed below and can vary between Harley-Davidson motorcycles and others. Exhaust leaks can cause decel pop, make sure the exhaust is sealed completely at the motor, and at any other connections.
Harley-Davidson: 1. For older Magnetti Marelli fuel injected bikes, adjusting the fuel table to remove fuel can help reduce popping. Highlight the zero percent column from 2,000 rpm to redline and enter in values from -40 to -50. Run the bike and see if the popping has reduced. Sometimes, the throttle position may not show zero at idle and should be correctly adjusted with the bike at full operating temperature to make sure it is reading zero.

2. On newer Delphi fuel injected bikes, we have found that adding fuel is needed to reduce popping. Highlight the zero percent column and instead of using negative numbers, try adding fuel to the map. Start with putting a value of 25 in the cells and see if the popping has reduced.

3. Adjusting the ignition table could also help in deceleration popping. Advance the timing in the zero percent column 3 to 5 degrees to see if popping has been reduced.
Metric and other: 1. Block off the fresh air injection systems. This will reduce the air being fed into the exhaust, causing the higher exhaust temperatures and detonation.

2. Adjustment to the fuel table in the zero percent fuel column from 2,000 rpm to redline, may also be needed to help reduce popping. A value of positive or negative 15-20 should be added and can reduce popping if it is still noticeable. Further adjustment may be needed, try increments of 10.

Do not do any changes below 2,000 rpm due to the fact that it could affect fueling at idle. Software Issues and Features

Answer

Hard Starting
Most Power Commanders are powered by the injectors on the bike. When you turn the key on, the fuel pump gets power and primes the fuel circuit. When this happens, the injectors get power, and the Power Commander also gets power and lights up. After a few moments, the fuel pump has pressurized the system, and usually shuts off. If the fuel pump shuts off, the injectors’ loose power, and the Power Commander shuts off. If you attempt to start the bike when the Power Commander is off, the bike will NOT start, until the fuel pump comes back on. The fuel pump may come on instantly, after a few engine revolutions, or on some bikes seemingly not at all. If the fuel pump does not come on, the bike will not start. We recommend starting the bike once you turn the key on. Do not wait for the fuel pump to shut off, or a check engine light to go out. Tuning Issues

Answer

Basic Troubleshooting
When troubleshooting, try removing the PC from the bike first. Does the problem go away? If yes, then load a zero map from us to the Power Commander. Does the bike run the same as it did with no Power Commander? If yes, the map you were using was incorrect for the vehicle. If no, the Power Commander is not working correctly, try a firmware update. Then test again with a zero map. The latest version of firmware is always available on our website. Tuning Issues

Answer

Predeveloped maps
The predeveloped maps on Dynojets’ website were created on a Dynamometer at our facility in Las Vegas Nevada. All of the maps we have created are listed on the website. These maps were created with the model vehicle listed, with the modifications listed. There is no way for us to have a predeveloped map with every possible aftermarket component. If there is not a map listed for your exact configuration, select a map with similar aftermarket components. If you have an aftermarket slip-on type exhaust, then select a map with a similar slip-on exhaust. If you have an aftermarket full exhaust, select a map for a similar full exhaust. If you have an aftermarket air cleaner, select a map with an aftermarket air cleaner. The map created for one vehicle, should work pretty well for a similar vehicle, with similar aftermarket components installed. Tuning Issues

Answer

Ignition Timing
The maps created by Dynojet have very few (if any) changes to ignition timing. Dynojet is very conservative in giving out maps to customers everywhere in the world. An ignition timing map that works well for one customer, may not work for another customer, in another area, with different quality fuel. Tuning Issues

Tuning Issues

Answer

Harley crank error or no start
If you are getting a hard, or no start problem with a Power Commander installed you may need to have the CKP (crank position sensor) on the bike checked for its output voltage. When they get to the lower limits of their specified range (weak) they can cause errors when the Power Commander is connected. It is a very common occurrence on the older Magnetti Marelli equipped bikes. Sometimes the sensor can pick up metal particles from the crankcase, removing the sensor and cleaning it off may correct the problem. If the sensor tests out at a voltage near or at the lower limits of the specified range, the sensor should probably be replaced as it is an indication that it will soon fail completely.

I am trying to communicate with my PCIIIusb using the supplied 9 volt adapter, but the computer does not see it. What should I check?
A low battery will keep the PCIIIusb from communicating. The PCIIIusb can quickly drain (about 20 minutes of use) a new battery, so make sure to not leave it plugged in longer than necessary. Also, make sure the cable is pushed all the way into the PCIIIusb’s port. Sometimes the connector needs a fair amount of pressure to fully seat it.

Answer

Applicable to PC III USB
The Power Commander software says "Serial: N/A" at the top right hand corner of the screen and does not show any serial numbers or "TP" readings.
Answer: The Power Commander USB needs to be powered up by either the bike or a brand new 9 volt battery via the battery adapter. If the unit is not powered up, the computer will only see a USB device being plugged in, but will not allow the software to communicate. If a battery has been plugged in for around 5 minutes, it may be too low on power to allow good communication.

The firmware program does not appear to work and I get an error code that has a "0x005, 0x008, 8001" or something similar.
These errors appear to be communication related. Unplug the USB cable from the programmer and switch USB ports on the computer. If the error still comes up, try switching the USB port to another one and restart the computer while the programmer is plugged into the USB cable. This should refresh the USB port. Power to the programmer does not need to be attached.

My throttle position in the Control Center software is not reading 0%
When the engine if fully warmed up and the bike is at idle the Control Center software should read 0% We have seen as high as an 8% variation in the throttle position from bike to bike. If yours is not reading “zero” at idle with the motor at normal temperature, then use the following procedure to correct it. In the Power Commander Control Center Software, go to menu “Power Commander Tools” and look for the tool to calibrate the throttle. The bike should always be running when setting the throttle position, as the voltage the sensor sends out can vary between when the bike is at “key on” and “motoring running”. The bike also needs to be at fully warmed up to its normal operating temperature. All you need to do is press "reset" while the bike running at idle, then quickly turn the throttle wide open till you hit the mechanical stop, then let go. Next press "Ok". You don't have to rev the bike out, the throttle just needs to go all the way to wide open and then back to idle.

My engine makes a popping noise on deceleration, how to I get rid of this?
Decel popping is caused by the detonation of unburned fuel in the exhaust pipe. This happens with high flow exhausts that allow more fresh air to be pulled into the pipe, causing the exhaust temperature to rise and detonate any unburnt fuel. Ways to reduce and possibly eliminate this popping are listed below and can vary between Harley-Davidson motorcycles and others. Exhaust leaks can cause decel pop, make sure the exhaust is sealed completely at the motor, and at any other connections.
Harley-Davidson:
  • 1. For older Magnetti-Marelli fuel injected bikes, adjusting the fuel table to remove fuel can help reduce popping. Highlight the zero percent column from 2,000 rpm to redline and enter in values from -40 to -50. Run the bike and see if the popping has reduced. Sometimes, the throttle position may not show zero at idle and should be correctly adjusted with the bike at full operating temperature to make sure it is reading zero.
  • 2. On newer Delphi fuel injected bikes, we have found that adding fuel is needed to reduce popping. Highlight the zero percent column and instead of using negative numbers, try adding fuel to the map. Start with putting a value of 25 in the cells and see if the popping has reduced.
  • 3. Adjusting the ignition table could also help in deceleration popping. Advance the timing in the zero percent column 3 to 5 degrees to see if popping has been reduced.

Metric and other:
  • 1. Block off the fresh air injection systems. This will reduce the air being fed into the exhaust, causing the higher exhaust temperatures and detonation.
  • 2. Many of today’s bikes (post 2007 or so) shut the injectors completely off during deceleration. If this is the case no adjustments made by the Power Commander, or any piggyback device, can help reduce this problem. On bikes that keep the injectors on during deceleration adjustments to the fuel table in the zero percent fuel column from 2,000 rpm to redline may help reduce popping. A value of positive or negative 15-40 should be added and can reduce popping if it is still noticeable.
Do not do any changes below 2,000 rpm due to the fact that it could affect fueling at idle.

How do I adjust the buttons on the faceplate of a Power Commander III?
  • With the ignition off, hold down all three buttons on the Power Commander III unit.
  • While still holding down the buttons, turn on the ignition and start the bike.
  • Release buttons. The light(s) should show up in the last place they were left, by default the center two lights.
  • Select the range you wish to adjust: Low, Med, High by pushing the corresponding button once, (these ranges are determined by taking the bikes RPM limit and then dividing it into thirds).
  • At this point holding that button down will move the lights down (leaning out the mixture).
  • Pushing the button repeatedly will move the light up (richening the mixture).
  • When the two center lights are lit up this is the “0” setting.
  • After making your adjustments wait 20 seconds before turning it off. This allows the settings to be saved to memory.

My Power Commander came with O2 eliminators, should I use these and what are they?
On bikes that use an O2 sensor in the stock exhaust have a closed loop area that can not be adjusted by the Power Commander alone. If you make adjustments with the PCIII in the closed loop area the O2 sensor will sense these changes and the ECM will alter the fuel curve accordingly. If you want to have full fuel control over the entire RPM range of your bike then you will need to bypass the closed loop area which the O2 eliminators will accomplish. If you are looking for the best fuel economy and not worried about making changed to the closed loop area you can leave the stock O2 sensors connected and still make changes outside of the closed loop area with the Power Commander.

I am having trouble starting the engine when the Power Commander is installed.
Most Power Commanders are powered by the injectors on the bike. When you turn the key on, the fuel pump gets power and primes the fuel circuit. When this happens, the injectors get power, and the Power Commander also gets power and lights up. After a few moments, the fuel pump has pressurized the system, and usually shuts off. If the fuel pump shuts off, the injectors’ loose power, and the Power Commander shuts off. If you attempt to start the bike when the Power Commander is off, the bike may take longer to start than normal, until the fuel pump comes back on. The fuel pump may come on instantly, after a few engine revolutions, or on some bikes seemingly not at all. If the fuel pump does not come on, the bike will not start. We recommend starting the bike once you turn the key on. Do not wait for the fuel pump to shut off, or a check engine light to go out.

I have had a Power Commander on my bike for quite a while and it has been running great. One day it just started running rough (like it was a cylinder was misfiring) so I disconnected the Power Commander and it went away. What could be the problem with the unit?
The most common problem we see with returned Power Commander is damage to the wiring harness. If the Power Commanders’ wiring harness is cut or nicked by the frame or sharp bracket it can short to ground. Once this happens a number of symptoms may be present, overly rich running, hesitation, stalling, etc. We suggest very closely inspecting the harness for any signs of damage. Small cuts may be difficult to see. If any damage is found, you can simply retape that area, unless the wiring is significantly shorted.

I ride a lot in the rain. Do I need to wrap my Power Commander in a plastic bag?
No, the Power Commander is a fully sealed unit. It is not necessary to cover the unit to protect it from water. The most important thing to is to make sure the port plugs are used.

Answer

Ignition Module
My ignition module does not show up after having the firmware loaded. If you go to "View" and "Power Commander Information" menu, the only module shown is Module 0. The Power Commander software does not show an ignition table, either.
Make sure that the latest Power Commander USB software (Version 1.1.3) is installed. If it is then try to reload the firmware into the Power Commander. The firmware must be loaded into the Power Commander and when you go to the "View" menu and "Power Commander Information", the firmware version should show 2.0.4. Once all of the above items are verified, an ignition table will show up when the ignition module is connected.

Answer

Bike runs rough regardless of what map is used or fuel value entered.
Verify the placement of the Throttle Position Sensor wire tap. It should be installed on the red wire with a yellow tracer on the GRAY connector side of the ECU. There is a yellow wire with a red tracer on the BLACK connector for the ECU that can easily be mistaken for the correct one. Also, verify that the connector is securely fastened and has not cut through the wire. If it cut through the wire, the Power Commander still may get a throttle position signal, but it may be erratic.

The bike will not start after washing the bike or running in rain for an extended amount of time.
These models have a rubber boot that needs to be transferred from the bike's OEM connector to ours. This keeps water out of the computer and if not installed, the sides of the ECM have openings that allow liquid right into the circuitry. In some cases, the computer can be removed and dried out for a couple days and it will function like normal, but this is not guaranteed. Make sure that the rubber boot, if it was installed, does not have any holes and is securely placed to keep water out as much as possible.

Answer

Applicable to 807-511
The Power Commander connectors have water in them after riding through rain or wet weather.
The stock connector on this model does not have pins in every single space and therefore Harley-Davidson put little rubber plugs in their place to seal up the open spaces. These plugs still seem to allow water by and it causes corrosion to start on the Power Commander connector. We recommend putting di-electric grease in our connector before plugging them together so that the moisture is blocked. Also, relocation of the connector to under the right side cover, on top of the ECM, may be beneficial.

If I live in the United States can I use one of the European maps?
Dynojet offers different maps for the US market and the European market due to the differences in the fuels. In most cases the fuel available in Europe will make a bike run much richer than the fuel available in the US. For this reason we recommend that you use a map that coincides with the region in that you live in. Although we have seen some European maps work well for US bikes so it may be worth trying.
