Important

This is an ECU reflash service, not a complete dyno tune. Final settings and suitability depend on the motorcycle's year, engine combination, fuel system, exhaust, and other modifications.

Before ordering: contact Monster Turbos with your Hayabusa year and current modifications so the appropriate flash strategy can be confirmed.
