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  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  Great service, had a long ongoing engine management fault with my outlander which others have tried to fix but failed. EPR were determined to fix the fault and did so at a reasonable price too. Very knowledgeable in engine management software. Highly recommended!

    5 star review  Fantastic job EPR. Very happy with the stage 1 tune on my normally aspirated V6 Chrysler crossfire. Very pleased with the results and improvement to throttle response. +Great work overcoming the cars stubborn traction control and general misbehaviour on the dyno and getting great results regardless.
