When we Remap we copy the data from your ECU, this makes it unique to your vehicle. It is saved by using your registration & chassis number. Software & hardware details are saved alongside this information. Then a tailored Remap file is created according to your specified requirements, for example if you want better fuel economy, or more BHP. This file is then reloaded back to your ECU. The whole process takes anything up to 3 hours to complete, depending on the complexity of the Remap.
Should it be required, the ECU can be returned back to it’s original state because the original is copied before the new Remap is added thus giving flexibility should it need to be returned to factory settings.
