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.

Happy customers = our success!

  • review rating 5  Had my Audi A3 Remapped by Carlos at EPR Tuning, the performance difference is incredible and I have also noticed 3-4 MPG increase in fuel efficiency over the last few months. I would highly recommend EPR!

    review rating 5  What a gent, Carlos gave me dates unfortunately none were suitable for me ,Carlos have up his own time to come to me after hours and turn my struggling Picasso into a new machine , I wanted a little more power to pull my caravan and that's exactly what I got, no more changing gears at the sight of a little hill, we now zoom up hills and when not pulling the caravan the car drives like a completely different vehicle smoother,quieter, less gear changes and as for mpg, if my on board computer is right im getting and extra 10 mpg on average , I've had it mapped for a week now, I'm completely over the moon, first class service from start to finish, thanks again Carlos

    review rating 5  Spoke to Carlos at EPR Tuning concerning a L200 which was gutless, lacked torque and acceleration. Carlos did a Stage 1 remap and what a difference! Just like driving a different vehicle! Carlos obviously knows what he is talking about. Would recommend EPR Tuning to anyone thinking of having a vehicle remapped.

  • review rating 5  Carlos collected my BMW 335d from my workplace for a stage 1 ECU remap and stage 3 xhp gearbox remap. The car was returned at lunchtime and had even had a couple of little extra features coded which was a nice surprise. Carlos is very knowledgeable and professional and I would recommend his services to anyone. Cheers

    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
