The program in the stock ECU’s have been developed to suite a wide range of riding conditions and riding skill levels also wide range of fuel types and grades. The results of this conservative programming are a compromise in performance and running condition of your motorcycle.

The motorcycle ECU controls the amount of fuel, amount of ignition advance, RPM limiters, Top speed limiters, Power Mode, Traction Control and other parameters of your motorcycle. The ECU does this by monitoring inputs from throttle position, rpm, gear position, intake air temperature, air temperature and coolant temperature.
