Remaps

An ECU (Engine Control Unit) remap involves modifying the software calibration data within your vehicle's engine management system. The factory settings are often conservative to account for varying fuel quality and market regulations. A remap optimises parameters such as fuel injection timing, boost pressure and ignition timing to improve performance, efficiency or both.

A professionally written remap carried out on a healthy, well-maintained vehicle will not damage your engine. The remap works within your engine's safe operating limits. We carry out a thorough vehicle health check before any remap to ensure the vehicle is in a suitable condition to proceed.

Yes — any modification to your vehicle, including a remap, must be declared to your insurer. Failure to declare a modification can invalidate your policy. We recommend contacting your insurance provider before booking a remap. Some specialist insurers offer competitive premiums for modified vehicles.

This varies significantly depending on the make, model and engine. Turbocharged diesel vehicles typically see the greatest gains — often 20–40% increases in power and torque. Naturally aspirated petrol engines tend to see more modest gains. We will advise on expected results for your specific vehicle when you enquire.
