ECU Remapping.

When a manufacturer make a vehicle they have to take into consideration all of the conditions it may be subjected to in all of the Countries around the globe in which they intend to sell the specific model of vehicle. This means instead of just optimising the ECU’s program or ‘map’ to deliver the best performance or the most fuel efficiency they have to make compromises to the map to take into account these potential differing operating conditions. These could include low quality fuels, extremes in temperature and altitude, differing emission laws and even the possibility that vehicle may not be serviced on a regular basis and in accordance with the manufacturers recommended instructions.

ECU remapping is to read from the ECU’s processing chip of the vehicles standard compromised map and adjusting various parameters within the map such as fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal control amongst others to release the true performance from the engine. It is a completely safe process as it is just giving the engine the performance it should have had in the first place before all the compromises were applied to the original programming. Every engine will have its own unique map and by adjusting this we can fine tune the characteristics of the engine; unleashing more power and in many cases reduce fuel consumption too.
