ECU TUNING INFO:
By extracting the map data from the ECU, the individual maps can be modified and reloaded to the ECU. If these maps are recalibrated correctly, the performance, drivability and efficiency of an engine can be improved. This process is called Remapping.
In most cases 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 and it will become clearer as you read on.
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. Think about it, a vehicle manufactured in Japan must be able to cope with the high air temperatures of India, but also perform in the freezing winter conditions of Russia. Therefore, when a manufacturer is producing a map for a vehicle to be sold globally, it has to make a compromise, between performance, and the vehicles ability to perform in a number of different environments. Couple this with the fact that there are extremely stringent regulations on the exhaust emissions of new vehicles, not to mention the political pressure of producing ‘green’ vehicles, it is easy to see why manufacturers detune their vehicles from the factory.
