Our Services

ECU Remapping

We extract the map data from the ECU (Engine Control Unit). The file is then carefully and professionally custom written for your vehicle. This involves adjusting various parameters within the map such as fuel pressure, boost pressure, ignition advance, throttle pedal control, amongst others. We provide the highest quality remapping service to drastically improve the performance, drivability and efficiency of your engine, resulting in up to 35% more power and torque and up to 20% more MPG.

OBD / Bench Tuning

ECU Remapping involves the modification of the operating parameters within the ECU’s program which is also known as the ‘map’. In most cases, the map stored within the ECU can be accessed via the on-board diagnostics port (OBD). However, in some cases the ECU has to be removed, the casing opened and specialist tools used to read the map directly from the ECU’s processing board. We adjust the parameters within the original map to achieve the best performance, fuel economy or a blend of both.

Gearbox Tuning

If you are looking for even more from your vehicle fitted with an automatic transmission, a gearbox TCU (Transmission Control Unit) remap perfectly complements our ECU Remapping service. A TCU remap provides many benefits from increased power and torque by relaxing the gearbox torque limiters, faster and smoother gear changes, improved low speed and off the line response and even improved fuel efficiency on some models. We currently support DSG Gearbox Tuning and ZF Gearbox Tuning for BMW’s.

    review rating 5  I messaged EPR tuning as I was interested to see what power increase I would see on my BMW 116i. I recieved a prompt response from Carlos who explained to me what power increase I would see and gave me a cost for the remap. I asked Carlos a couple of questions about the remap / engine and he seemed really knowledgeable in his responses and I felt I was able to trust him to carry out the remap for me, so i decided to go ahead with the very reasonable quote provided. I left my car with Carlos for a couple of hours whilst he carried out the work, he sent me a message to inform me that the works were done and I took it for a test drive. Safe to say I was very impressed with the performance increase and the car feels totally different! It has now been over a month since the car has been remapped by Carlos at EPR tuning and I have had no issues whatsoever and would definately recommend this company to anyone! I will be using EPR tuning to map all of my cars in the future ✅🚙

    review rating 5  Range Rover Sport Stage 1 Remap. The guy's at EPR Tuning have done great job as the car is so much better to drive. It has improved the peddle response and gear changes are quick and smooth. The car's ability to take on a long steep hill is effortless. Thanks Guy's Great Job. Cheers Graham
