ECU Remapping

What is ECU Remapping?

ECU Remapping is a modern day equivalent of engine tuning. All vehicles manufactured since 1999 are controlled by an on-board computer which is known as the Engine Control Unit (ECU).

The ECU controls a number of different engine functions such as fuelling, boost pressure and ignition timing. Within this computer, a file stores the manufacturers settings which have been mapped to allow for build tolerances into their engines and to comply with emission targets, cope with sub-standard fuels found in some countries, operate in areas with extreme environments and, allow for irregular service standards. It’s these restrictive under-performing manufactured settings which we are able to optimise and remap. The parameter settings within the file can be easily amended by using advanced technology therefore, tuning the ECU to your requirements making the vehicle more responsive with increased power and also fuel efficiency. Whilst this may sound complicated, the principle is actually incredibly simple and can be carried out at your preferred location in as little as two hours. In simple terms, we can increase the performance of your vehicle, improve fuel efficiency and/or both. No matter what vehicle you drive, how often you drive it or what you use it for, Car-Wizard can make it:-


Up to 35% more powerful
Up to 15% more fuel efficient
And much more enjoyable to drive

We are so confident of the ECU remapping we provide that we are happy to offer each and every one of our customers a 100% money back guarantee.
