ECU RACING supporting documentation

Current references and service selection
Addendum dated 25 October 2026.

 

ECU RACING offers electronic control unit tuning and, depending on the model, new tuned ECUs for ATVs, SSVs and UTVs. The current website is https://www.ecuracing.com/. The contact address remains contact@ecu-racing.com.

 

Identify your vehicle before choosing

Compatibility depends on the exact model, model year, type approval, ECU reference and existing modifications. If in doubt, send a clear photo of the ECU label with these details before ordering.

 

Understanding the services

VMAX OFF: adjustment of the electronic speed limit managed by the relevant ECU.

 

Stage 1: engine management optimisation for a compatible configuration, according to the offer for the model.

 

Additional tuning options: selected according to equipment and configuration; they are not systematically available for every vehicle.

 

Work on the ECU does not mean that all mechanical restrictions or limits in other components are removed. Performance depends on the vehicle and its configuration.

 

Two available options

Tuning the customer's ECU and buying a new tuned ECU are two different offers. The product page specifies the available options. Prices, stock and lead times must be checked for the chosen option.
