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 numerous parameters within the map such as fuel pressure, boost pressure, ignition advance, throttle pedal control, amongst others. Our tuning calibrations are developed in-house on our Rolling Road. This allows us to deliver the highest quality custom remapping service, 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.

What a hassle free, professional, knowledgeable, friendly, enjoyable and with superb results experience it was from Carlos, EPR Tuning..!
I have a Jaguar XF SV8 4.2L Supercharged which I've fitted various modifications to recently. She already goes like a rocket before the EPR Stage 1..! So after two hours and two coffees from Starbucks, returned to find my Jaguar had sprouted wings, having taken off from a racing circuit...not really of course but she feels like that now. Sounds throatier, smoother, a lot more bhp and torque which is very noticeable immediately..! Last but not least she's much more fuel efficient which is a real extra bonus (obviously I didn't buy the car for economy...)..!
All in all a fabulously great service from Carlos and Team... I'll be back for some more of the EPR TUNING in due course, my youngest son will be having his Stage 1 tweeks on his Volvo S80 II AWD 4.4L V8, it's unassumingly quick already...!
Highly recommended indeed, thank you very much, EPR Tuning...appreciated and very refreshing nowadays!Adrian J Thornton
Brilliant service, my Land Rover is running much quieter and there is power in reserve for overtaking which wasn’t there before. Would recommend highly..

I've just had my vehicle tuned by EPR and they were able to book me in at short notice and completed the work in only a few hours finishing earlier than I expected. Not only that but the readouts were able to highlight servicing suggestions to keep my car running efficiently. The increase in power and torque are definitely noticable making my drive home more enjoyable. Highly recommended if you want a little extra power.

- I took my E93 330d in for a Stage 1 remap after some very informative discussions with Carlos to ensure that the adjustments would not exceed the capabilities of the engine and transmission. He was extremely professional and the results were incredible! An already capable car was transformed with smooth and strong power delivery throughout the range. Carlos even rectified an issue I had with a sensor, nothing to do with the remap, and couldn't have been more helpful. Thanks again!
Ian Mitchell
Top experience from start to finish.
Had a great chat with the owner who explained all the dyno runs in detail, was very impressed with the end result , car feels transformed!
Will definitely use again in the future

An incredible experience, very professional, reliable, good value for money. You don't often find people as friendly and professional as Carlos who runs EPR. An absolute pleasure. I cannot recommend him and EPR Tuning highly enough. I live in Bristol and there are alternatives here, but I would travel the distance again.
