This guide is intended for informational and educational purposes. Modifying your ECU may void your warranty and could be illegal for street use in some jurisdictions. If you own a modern Honda motorcycle (such as the CBR1000RR-R Fireblade, CB650R, CBR600RR, or Africa Twin), chances are your bike runs on an ECU manufactured by Shindengen . While these ECUs are robust and reliable, they come from the factory with conservative fuel maps, restricted throttle openings (especially in lower gears), and mandated emissions compliance.
