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.
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.
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!

Wow Carlos your the man. I’m so grateful that you did my remap on my countryman, the last one this year for you.. I can’t believe my car produces 286 bhp and 415 nm of torque. It’s like a rocket now it goes like S- - - of a shovel Even in green mode it’s fast, flick the gearstick over to M/S and let’s just say your holding your steering wheel tight and then when you use the toggles to mid and sport it’s so quick. Amazing 🤩 I thought driving to Bideford is far but I just wish the journey was longer as I returned back to coventry I was smiling all the way home and beating cars on the road. Carlos really knows how to custom remap cars. Any cars I buy in the future they will definitely be coming to EPR tuning for there custom remap. Carlos is professional and he keeps you informed on what he’s doing step by step and he treats your car with respect. Get in touch with Carlos you will not be disappointed!!!
Carlos was excellent!! 10/10 customer service. I was only in the area for a few days, Carlos went out of his way to make sure he could fit me in when it suited me, he was very professional and excellent and what he does. Would highly recommend

Very good service it’s good to hear the confidence experience and the knowledge in Carlos very happy with the result of my vehicle.Well Done Deano
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.
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!
