ECU tuning, also known as remapping, is the process of modifying the software that controls your vehicle's engine management system. This allows for adjustments to factors such as fuel mixture, ignition timing, and turbo boost pressure, optimising performance and efficiency

When performed by experienced professionals using quality equipment and following manufacturer guidelines, ECU tuning is generally safe and can even prolong engine life by optimising performance parameters within safe limits.

ECU tuning can improve fuel efficiency by optimising the engine's performance parameters, leading to more efficient combustion and reduced fuel consumption. Eco tuning, in particular, focuses on maximising fuel efficiency without compromising performance.
