Personal watercraft engines are small, highly stressed and run at high rpm almost continuously. The calibration work concentrates on ignition timing and on fuelling in the top third of the rev range, where the factory map is deliberately cautious — that is where the acceleration out of the hole and the top-end pull come from.
Everything is kept inside the safe operating window of the engine: intake temperature, boost where fitted and injection quantity stay within limits, so the engine is not left running lean at sustained wide-open throttle.
We do not physically remove or modify any hardware — we only recalibrate the ECU software map. Compliance with the emissions regulations in force in your country remains the responsibility of the vehicle owner.
