ECU Remapping

Our technicians link to the vehicles ECU or "brain" with a laptop PC through the vehicles diagnostic socket and read the current engine management file which is then sent to our files office and custom optimised for you vehicle. The technician programs the new Unity Performance optimised file into your vehicle and you then have opportunity for yourself to experience the amazing results. On some vehicles it is not possible to carry-out this function be the diagnostic socket so in this case the ECU is removed and either a chip change or boot loading function is carried out, direct into the ECU. The final effect is exactly the same, only the process is different. Depending on the vehicle, the remap normally takes less than 1 hour to complete the re-map. You can choose to visit one of our dealers, our head office in Iver or, dependent on area we can visit you at your home, office.

Yes, Unity Performance tuning is extremely safe. We only work within the manufacturer's mechanical safety limits. Our engine management software is developed through extensive testing to ensure long-term reliability and engine longevity.

Manufacturers build cars for a global market, accounting for poor fuel quality, extreme climates, and neglected maintenance in some regions. In Europe, where fuel and maintenance standards are high, we can safely unlock the hidden performance manufacturers leave on the table.

We provide a comprehensive software warranty. If your tuned file is ever overwritten by a dealer update, we will reinstall your performance software free of charge. We also guarantee the safety and performance of our proprietary maps.

Remapping (also known as ECU tuning) is the process of modifying the software in a vehicle's engine management system. We adjust parameters like turbo pressure, fuel injection, and ignition timing to optimize performance and efficiency.

Yes, we offer a 30-day money-back guarantee. If you are not completely satisfied with the performance increase or the driving feel of your vehicle after remapping, we will return it to stock and provide a full refund.

We always recommend informing your insurance company of any modifications. Most insurers are now very familiar with remapping and, in many cases, it does not increase the premium significantly for reputable tuning like ours.

Absolutely. We keep a secure backup of your vehicle's original factory software on our servers. This allows us to revert your car back to 100% stock at any time if required.

Technically, any modification can affect a warranty. However, our remaps are designed to be 'invisible' to standard dealer diagnostic tools, and we follow manufacturer service guidelines to minimize any risk.

A remap improves throttle response, increases power (BHP) and torque (NM), and often improves fuel economy on diesel engines. The vehicle will feel more responsive, pull harder through the gears, and provide a much smoother driving experience.
