Even though this unit is adjustable down to 100rpm increments & 1% throttle changes, most people will still find it beneficial to go ahead & run a Powercommander in conjunction with the new ECU. It just aids in the ease of tuning, but if you have the time, dyno access & ability you can purchase the seperate cable & tuning software to reprogram the ECU itself.
1. You WILL need a Race Wiring Harness or US Spec Harness to make this work on a bike with the HISS system
2. You WILL still get a MIL error code when
you disconnect the HESD unless your software has been set
to disregard the HESD. Again if you purchase the software
& cable available at an added expense to reprogram
certain functions of the ECU then you can turn the HESD
off/on as well as setting the damping levels on a scale
of 1-10 for both constant speed & acceleration.
6. Since racebikes don't have cooling fans, the radiator fan will no longer function, so if you are commuting or doing any type of stop/go traffic you will need to wire in a manual ground wire on a switch so you can turn the fan of/on.
7. The rev limit is increased to 13,800 which is way over the stock rev limiter & while this sounds like a good thing it is very very easy to damage your motor if you are not careful & overrev the bike.
The additonal rpms is scary to say the least
because it revs up there so fast & anyone that knows
engines knows that even as little as a couple hundred
more rpm over the stock redline even on built motors can
be catastrophic so I simply cannot over-emphasize how
much caution needs to be taken when running at the top of
the rev range, but this ECU flat fuckin ROCKS!
9. Do not use the PCIII USB Accelerator Pump option with this ECU
The low fuel light does continue to function as normal...
