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 various parameters within the map such as fuel pressure, boost pressure, ignition advance, throttle pedal control, amongst others. We provide the highest quality remapping service to drastically improve the performance, drivability and efficiency of your engine, 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  Had my Audi A3 Remapped by Carlos at EPR Tuning, the performance difference is incredible and I have also noticed 3-4 MPG increase in fuel efficiency over the last few months. I would highly recommend EPR!

    review rating 5  I had my BMW 330cd remapped today by Carlos at Evolve Tuning as I was looking for a bit more power but also the car wasn't running right and smoking excessively on full throttle due to a sensor issue. He not only transformed how the car drives but he also diagnosed the issue. He also deleted the egr from the ecu resolving the problem and it now runs perfectly. Such helpful and friendly service. I'd thoroughly recommend them!

    review rating 5  Carlos carried out a carbon engine clean for my 330D. Since having it done the car feels a lot smoother and there's definitely less 'rattle' that comes with a diesel. I have noticed acceleration is a lot smoother too! I'd definitely recommend the engine clean to anyone who's considering it.

    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 👍🏻
