With Accel’s Self Learning Module you regain control of your fuel injected ride. This module eliminates the “bang & pop” associated with mis-programmed ECU’s due to intake and exhaust modifications. Accel’s SLM is one of the easiest Fuel Injection Controllers as it features automatic self learning technology that compensates for changing loads, weather conditions and altitude while you ride. It also re-calibrates and optimizes for modifications such as exhaust pipes, intake, air cleaners, cams, etc. There is no need for costly dyno tuning sessions, downloading calibration files to a lap top or re-flashing the factory EC, simply plug it in and ride. Unit features direct plug-in connections for the OEM Throttle Position Sensor, Crank Position Sensor and O2 sensors. Units for models that were not factory equipped with O2 sensors come with one O2 sensor and one weld-on sensor bung, upgrading your bike to the latest and already proven “Closed Loop” technology for greater engine efficiency resulting in improved performance.
