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 ECUβs program which is also known as the βmapβ. 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!

Visited EPR tuning this week and handed my Mini Cooper S over to Carlos. Amazing service and went out of his way to fit me in.
Fell in love with my car all over again, drives Incredible and has improved all aspects.
Even managed to have a great tidy up with Matt at gleaming motors at the same time.
Great set up, great service, highly recommended.

7/28/2018 I bought a Van which had been mapped, and it was terrible. Power delivery wasnβt 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 Iβm 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.
