ECU remapping (sometimes called engine remapping) is when the settings on your engine control unit (the ECU in question) is altered. This can vastly improve performance, and is a delicate operation that requires the right equipment and the right kind of expertise to get right. Luckily, at TCM Tuning, we have ample supplies of both. Whether you drive an Audi, BMW, Volkswagen, Bentley, Porsche, Seat, or pretty much anything else, we have the tools and the experience to do the job right.

As well as tuning, remapping, and diagnostics, we also install high-quality CANbus immobilisers from Autowatch. The Ghost II is the original, and still the best. It interacts directly with your car’s Controller Area Network, preventing it from activating without a special code. This sequence is chosen by you and means you needn’t worry about key or fob theft again.

If you encounter a fault with your ECU, or it fails to work entirely, the unit may need recoding. This involves resetting the entire unit back to its original factory settings. This will allow us to reconnect it to your car and conduct an extensive remapping or tuning from scratch, once it is recoded.
