Performance remaps

ECU remapping is a popular way to improve the performance of your vehicle. By adjusting the settings of your engine control unit (ECU), we can optimize your engine’s power output, torque, and throttle response. At ACR Tuning, we believe that reliability and drivability are equally as important as performance. ECU remapping can offer incredible gains in power and torque, but we also believe in safe and sensible tuning. The remap figures we quote are realistic and our software calibrations are designed to optimise performance without compromising reliability. Here are some of the benefits of ECU remapping for performance:

1. Increased Power – ECU remapping can unlock hidden power in your engine, allowing it to produce more horsepower and torque. This can result in faster acceleration, higher top speeds, and improved overall performance.

2. Enhanced Throttle Response – By remapping your ECU, we can improve the response time of your throttle, giving you more control over your vehicle and a more enjoyable driving experience.

3. Improved Towing Capability – If you use your vehicle for towing, ECU remapping can help to improve its towing capacity by increasing torque and power output.

4. Better Fuel Economy – Contrary to popular belief, ECU remapping can actually improve your vehicle’s fuel economy by optimizing the air/fuel ratio and ignition timing. This can result in better efficiency and lower fuel costs over time.

At ACR Tuning, we offer ECU remapping services for both petrol and diesel vehicles. Our team of experts can help you get the most out of your vehicle’s performance, whether you’re looking for a subtle improvement or a major overhaul. 

Please note, if your vehicle is less than 3 years old it is unlikely that your ECU will be able to be Remapped. 


Before carrying out any remapping we always carry out a full diagnostic health check as well as extensive datalogging to ensure the vehicle is in the safe state of health for tuning. We believe that driveability and reliability are as important as performance and therefore when you choose ACR Tuning to remap your pride and joy you can rest assured that your vehicle is in safe hands.

Stage 1 Tuning

This is designed for a vehicle in standard form with no mechanical modifications. Our Stage 1 software will increase BHP and torque whilst also providing an increase in MPG. Throttle response will also be improved with flat spots ironed out with smooth power delivery.

Stage 2 Tuning

This provides a bigger increase in BHP and torque than our Stage 1 software and will still improve fuel efficiency and drivability. Hardware upgrades will be required before our Stage 2 software can be applied. Please get in touch with any questions etc.
