CFORCE 520: compatibility, testing and ECU tuning

ECU RACING helps CFMOTO CFORCE 520 ATV owners choose between remapping their ECU and a new programmed ECU.

VMAX or Stage 1? VMAX targets electronic speed restrictions managed by the ECU. Stage 1 includes this work and adds engine calibration optimisation for in-gear acceleration and throttle response.

MSE6.0 or MSE8.0? The ECU reference, model year and ATV version help confirm the right tuning service. Any mechanical restrictions must be checked separately.
