Is ECU remapping safe?

It is important that ECU remapping, or car tuning, is carried out by highly skilled and qualified technicians, using a leading diagnostic system that caters for customised car remapping and optimises engine performance and power within safe limits.

At Quality Car Service, every single ECU remap performed by Quality Car Service is unique.

Our remapping service involves a completely safe and customised car tuning process that allows for total control over all parameters at any given moment.

It does not disturb the safety functions of the car; all original manufacturer’s data, such as VIN number and serial numbers, are re-instated exactly as they were before the remap. Any changes cannot be detected via the standard diagnostic checks from your dealer.

What is ECU remapping?

Quality Car Service plugs the world’s leading diagnostic system into your car to check for existing faults, if any, before downloading your car’s ECU software for backup and analysis.

Your software is then optimised by our tuning experts to provide the new characteristics and loaded back onto your ECU and your car tested.

Try the Quality Car Service ECU remapping service for 30 days and, if you are not pleased with the results, you can come back to us and we will uninstall it with a full refund.

A professionally-remapped engine with a well serviced and maintained engine will not cause technical faults, but in the unlikely event the installation becomes faulty, as part of our lifetime warranty against software faults, we will re-install it free of charge.

    Cannot recommend Ben and the team enough. After a nightmare experience buying a car from Trade Centre UK, i had no end of issues that they would not resolve (a whole other story!!). Having used QCS multiple times over the years, I took the car to them and they were so patient, running various tests and fixed all the problems. Their communication was great and they took a lot of stress out of... Read More

    Booked my car in for its MOT and the service from start to finish was amazing! Nothing was too much trouble and was kept updated during the process. Also had my husbands flat tyre in the boot and they fixed it there and then without any drama. Quick and easy to use the online booking system. Will be recommending to friends and family.
