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.

  • review rating 5  Great service and value, Carlos really seems to know what he's talking about. A lot of cowboy mappers are numbers driven, Carlos talked me through it and left me satisfied that my van has a safe map. Great drive home much more torque and that bit more for overtakes... Will be back for my beetle next...

    review rating 5  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.

    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!

    review rating 5  Excellent and truley professional tuning company. I have been too many so called tuners in the last 10 years and nobody compares to Carlos. His attention to detail is unbelievable, not your bang average tuner who puts on a genric map and hopes for the best promising massive gains that ruin your car. Carlos data ran my car 5 times to ensure it had the perfect map and even tuned the car down slightly to ensure the flywheel didnt scream. Couldn't recommend enough. TOP WORK. TOP GUY.
