Stationary manual adjustments will let you adjust the fuel map, EITMS (Engine Idle Temperature Management System) and idle speed, AFR (Air Fuel Ratio) can be set slightly richer or leaner. Ignition timing can be adjusted and includes a rev limiter. New maps can be downloaded from Vance & Hines and through the on-bike sensors the system can be run in AutoTune mode, which enables the bike to recalibrate the fuel map real time to the specific conditions and even the quality of fuel that is used. When the Android or iPhone is installed on the bike, live sensor data, like speed, RPM, cylinder head temperature, voltage, gear selection etc. can be seen on the display of the smartphone. Note: Once the FP4 is used on a bike it is 'mated' to that specific ECU. You will not be able to use the same FP3 on another bike.
