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 several 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 4WD Rolling Road. This allows us to deliver the highest quality custom remapping service in Devon, Cornwall and Somerset.

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 from the vehicle and the map read directly from the ECU’s processing board. We have the latest and most advanced equipment in the industry, the knowledge and the experience to carry this out safely.

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 torque limiters, faster and smoother gear changes, improved low speed and off the line response to name a few. We currently support DSG and ZF Gearbox Tuning for BMW’s.

    5 star review  Just wow. From the incredibly helpful, polite and efficient service to the amazing upgrade in every way to the drive of my vehicle, I cannot thank EPR Tuning enough. There are so many companies talking the talk around vehicle tuning but very few that actually can walk the walk. Cannot fault EPR Tuning from the service to the results. Thank you so much.

    5 star review  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!

    5 star review  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.

    5 star review  Fair plays EPR tuning what a superb service you provide, whether its opinion on parts or working your magic on the tuning honestly the best service you will receive. 1st time at EPR the ECU kept pulling back so couldn't tune got advised to fit new plugs and in the 2 weeks between sessions constant advice was given and assistance where needed. The benefits of data logging right here folks no flash drive put onto your car just proper dynamic tuning. 2nd session and the results are pleasing serious smiles per miles..... and a lil more to come next time, highly recommend keep up the amazing work EPR was truly a pleasure....
