A couple of weeks ago Mark did a stage 1 remap on my 2019 Citroën C5 Aircross 2.0 BLUEHDI, since then I’ve driven to north Wales and back, what a difference it’s made, higher mpg and quicker with more torque at lower revs. It’s made quite a difference. Thanks Mark, I will certainly recommend you to my friends and family.

FAQ
Questions Often Asked About ECU Remap Services
Below are some questions and answers relating to remapping in South Wales. If you have any other questions please call us.
Are ECU remaps in South Wales covered by a warranty?
Why ECU remap your car or vehicle?
How do we remap your vehicle's ECU?
The engine is controlled by the ECU which we access through the OBD diagnostic socket inside the vehicle. After a vehicle diagnostic check, our remap tool reads your vehicle’s engine data, we carefully modify and fine-tune it, then load it back into the vehicle’s ECU. The vehicle is then road tested by you to feel the improvements. The whole process usually takes about an hour.
Why is ECU remapping not done by the car manufacturer?
Warranty, main dealer servicing and MOT after an ECU remap
Diagnostic codes and safety settings set by the manufacturer are retained. Only the engine control settings are enhanced, which makes the remap undetectable by normal dealer servicing or MOT testing. Original settings are kept on file so we can revert if needed.
Why drive a standard vehicle?
You can enjoy up to 30% more power and 50% more torque in turbo vehicles, around 10–15% in non-turbo, plus better MPG. Choose from economy, towing torque, Stage 1, or max power – or let us recommend the ideal option for your vehicle.
Benefits of a remapped vehicle
Increased horsepower, increased torque, better throttle response, smoother power delivery, improved MPG (especially turbo diesel), safer overtaking with no flat spots, and savings on motoring costs from better fuel economy.
Why should you ask Elite ECUs to remap your vehicle?
We’re a warranted company providing custom remaps made just for your vehicle – not generic files copied from similar cars. If you’re not happy at the time or within 14 days, we’ll revert it and refund you. We’re that confident in our work.
