ECU flashing is not only MORE COST EFFECTIVE than any other tuning solution, it is far SUPERIOR to any other tuning solution because it also allows for more precise tuning of fuel and ignition timing maps which automatically compensate for changing atmospheric conditions. It also allows for the modification of parameters that are not otherwise adjustable through other tuning solutions, such as electronic throttle mapping.

Our Mail-In ECU Flashing Service also comes with FREE future mapping updates for as long as you own the motorcycle. The only cost you are responsible for is the shipping of your ECU.

  • Custom IAP Fuel Maps (Intake/Exhaust Specific)

NOTE: With all aftermarket exhaust systems, you will need to plug/block off your AIS for proper functionality.

NOTE: You may have a temporary check engine light on after your ECU is flashed due to the ECU being powered up outside of the bike. This should clear itself in TWO ride cycles but may need to be cleared manually. Rideability will not be affected while the check engine light is on.
