The Rev X-tend feature will allow your Harley Davidson (V-rod excluded) with a stock
ECM to rev to 6200rpm. No longer is there a need to have your ECM reflashed by your
dealer. Now you will have full control over your fuel curve up to 6200rpm with the
PCIII USB. This feature can be enabled on Power Commander III USB units with part
#801-511, 802-511, 805-511, 807-511, 810-511, 811-511, 812-511,,813-511 and 814-511.
To enable units currently in the field it will require a firmware update. The unit
can be sent in to Dynojet for $25.00 and we will enable this feature and send it
back to you. You also have the option of purchasing a firmware programmer and the
necessary software which will allow you to update an unlimited number of units.
This package is part #HDREV and can be purchased for $40.00.
Note: Purchase the kit shown above with everything you will need to reprogram your
Power Commander III USB only if your serial number (shown in the upper right corner)
is NOT higher than 060201000001. If it is, the upgrade has already been installed.
Note: This upgrade is NOT for V-Rod model motorcycles
To access the Rev Xtend and start up fuel features open the Power Commander Control
Center software. This software needs to be version 3.1.3 or newer. While the software
is communicating to the PCIII hit CTRL-F on your keyboard. This will bring up a
window called Power Commander Features Dialog. Check the box next to the feature
that you want to enable.
If you check the Extend Redline feature then your bike will hit the rev limiter
at 6200rpm. A different RPM setting can not be entered. If you ever want to turn
this feature off just uncheck this box.
If you check the Start-Up Fuel adjustment you will have the ability to richen or
lean your fuel mixture during start-up without affecting the base map. This feature
is normally only used on highly modified engines that have a hard time starting
To adjust the settings of this feature go to POWER COMMANDER TOOLS - START UP FUEL.
This will give you two fields to adjust. The first field is the Percent of fuel
to add or subtract during start-up. By inputting a value here you will offset the
fuel by a given percentage above and beyond the stock ECM and Power Commander. The
second field is the number of engine revolutions (or time) that this feature will
be active for. A normal value would be around 150.
