What is ECU Remapping?
ECU remapping is a software upgrade that adjusts the factory settings of your Engine Control Unit (ECU) to improve performance, efficiency, and drivability. Manufacturers limit a vehicle’s full potential to meet regulations, but with a custom remap, you can:
- Enhance throttle response for a sharper drive
- Optimise fuel delivery for better economy
- Improve acceleration and power delivery for a smoother experience
- Reduce turbo lag for a more responsive drive
- Adjust torque output to match performance upgrades
Our custom ECU tuning is designed to suit your individual vehicle and driving style, ensuring maximum performance without compromising reliability.
