FAQ | Bucks ECU Remapping | Remapping in High Wycombe

Your vehicle has an electronic ‘brain’ called an ECU (Electronic Control Unit) loaded with software that controls many of your car’s engine functions and settings. Our specialist software replaces that already on your ECU; the different settings it incorporates bring about the improvements to your vehicle’s performance and drivability discussed in the ‘services’ section of this website. You don’t ‘burn your boats’ in having settings to your vehicle’s ECU altered as we make a backup of the original software and store it securely so as to reinstall it to your ECU if ever this is required. It’s much like making a backup of your computer or smartphone.

Yes. It’s your responsibility to advise your insurance company of any changes made to your vehicle.

They do – just in different ways. Many manufacturers often offer different power versions of the same engine, and these differences are often purely created by the engine being tuned and mapped differently. For example, the Ford 2.2 TDCi diesel engine is offered in at least four different power output guises yet it’s exactly the same engine. In the interests of standardisation and saving on production costs, it’s more financially effective for a manufacturer to provide just one engine mapped to different power output options.

In most cases, the answer is no. Because we always save a copy of your vehicle’s original ECU software, we can return your car’s ECU to standard “factory settings” before you take it in for a service or warranty work.

This can happen usually when the manufacturer introduces an update applicable to certain models. Your dealer’s software update would overwrite the Remap software much like when you update the operating system software on your computer or smartphone, but don’t worry; we’ll gladly reinstall the Remap software free of charge. If we have to remove your vehicle’s ECU as opposed to updating it in situ there might be a small cost – we’ll advise you of this before starting work.
