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.
Happy customers = our success!

First time I’ve had a car remapped and what a difference Carlos has made to my little BMW 125i, very happy with the gains, so much pull now. If you’re thinking about getting a remap for your car, don’t hesitate, get it booked in at EPR, you won’t be disappointed. Highly recommended. Andy Beatty
Carlos rolled back and stage 1 remapped my Skoda Yeti. What a difference.to performance. Delighted to have used such a knowledgeable and professional person. Thankyou Grahame Hounslow
My UP GTI came out feeling like a new car after Carlos worked his magic. Gains exceeded my expectations and the car is wonderful to drive. Customer service was second to none - Carlos is a lovely guy and clearly a true enthusiast.

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.
