How does an ECU remap software work?

Since the mid-1980s, most engines have been controlled by an on-board computer, the engine control unit (ECU). It controls the ignition timing, fuelling, boost pressure and many other functions for all given engine speeds and loads.

After extensive development and testing, optimum settings have been developed for your make and model of vehicle. We ensure that each remap is as individual as the software inside your ECU, safely eliminating those ‘performance compromises’. The new remap is based on the original programme in your vehicle.

In many cases this remapped program is installed remotely through the car’s diagnostic port so there’s no replacement chip, and we don’t touch the ECU itself. However there are some models that can only be done direct to the ECU.

And we always test your vehicle before handing it back for you to enjoy, just making sure everything is operating as it should be. If you’re not happy, we offer a full money back guarantee.

We specialise in Turbocharged petrol and diesel engines (TDI) but non-turbos can also be upgraded, with less dramatic gains. Typically you can expect 25-35% from a turbo diesel, 20-25% from a turbo petrol and up to 10% (with much better throttle response) from a normally aspirated petrol engine.

Please note: Tuning files are available for most but not all vehicles post year 2000.
