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.

Happy customers = our success!

  • review rating 5  I dropped my MK 7 Golf GTD off to EPR for a stage 1 remap and in less than 2 hours it was completed. The power delivery now is very smooth and it just keeps pulling and pulling right the way through the rev range. The rate in which it gathers speed now is very impressive! Many thanks Carlos for a great service 👍🏻

  • review rating 5  I bought a Van which had been mapped, and it was terrible. Power delivery wasn’t smooth and it drank fuel. Spoke to Carlos and he did a live run and it showed the problems. I opted to revert to a standard map as I was looking for better fuel economy and a smoother drive. Carlos remapped the van and it was a remarkable difference. I now get twice the range from a tank and I’m not down on power. The van runs so smoothly and gives twice the MPG without feeling any less powerful. I would highly recommend his work. Very knowledgeable and a professional service.

    review rating 5  5 Star Service I’d been thinking about tuning for a while but didn’t really know who to trust. Carlos was just fantastic, really knowledgeable which gave me the assurances I needed. Got the work done and was so happy with the results I’ll never go anywhere else for other cars! Thanks so much!
