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.

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.

I've just had my vehicle tuned by EPR and they were able to book me in at short notice and completed the work in only a few hours finishing earlier than I expected. Not only that but the readouts were able to highlight servicing suggestions to keep my car running efficiently. The increase in power and torque are definitely noticable making my drive home more enjoyable. Highly recommended if you want a little extra power.

- 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!
