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. If you live in Sunbury-on-Thames and want more power from your car we are the place to go.

📞 Call 01753 439321 to book your remap.
