Keihin self learning ECM refreshed for FinBro has a RPM limiter set at 12,500 RPM, instead of the OEM 9,500 rpm that is set in the original GROM/MSX125 ECM. It is capable of self adjusting fuel trims and ignition tables while you ride to deliver an accurate and safe performance, it is a completely autonomous system....no more software updates, data cables, laptops, secondary sensors, building/searching or asking for maps needed. It will automatically learn and store the adjusted fuel trims and ignition tables by itself using the OEM O2 sensor already on the engine. It will automatically add or remove fuel to all changes made to an engine, including boosting engine power: big bore kits, 4 valve heads, intakes, exhausts, cams, larger heads, pistons etc. The base data is also programmed for a more agressive engine at higher rpm's.


This ECM is not equipped with cold start circuitry, so using slight throttle operation is normal for the first few moments when starting in colder weather. A minor adjustment on the wire loom is required and an extra female end jumper wire is provided for you. It involves re-routing only 1 wire, and disconnecting 1 wire depending on your year model.
