HOW DOES ECU REMAPPING WORK?

The performance of a vehicle with factory settings is so far away from the engines true potential performance it could be said that they are electronically detuned by the manufacturers. Sounds crazy? I know, but there are several significant reasons for detuning a vehicle. When a vehicle is manufactured for global sale it must be able to cope with many different environments. The vehicle must be able to cope with poor quality fuels sold in less developed countries, perform at high and low altitudes, cope with poor or non existence servicing and also perform with severe differences in temperature.

How does a WR Tuning ECU remap for petrol, TDi, GTi and HDi engines work? 
Engine chipping came about after the introduction of the ECU. Since the early 1990s, most engines have been controlled by an on-board computer, the engine control unit (ECU), which amongst other functions, defines the ignition timing, fuelling and boost pressure for all given engine speeds and loads.  ECU remapping lets us change the way the engine is controlled – and engine tuning gives you a more engaging drive.

WR Tuning develops a unique ECU remap for each car. HDi engine tuning is different from a GTi remap. A turbo diesel remap for one car will be different from another. And petrol engine ECU remaps will be different again.

WR Tuning invests extensively in development and testing and we bring over 10 years of experience to the job. We arrive at the optimized settings for your make and model of vehicle, ensuring that each remap is as individual as the software inside your ECU, safely eliminating those ‘performance compromises’.

In most cases this remapped program is installed through writing to the ECU itself.
