It is usually assumed that a brand new car is in its best condition at the time of its purchase. Certainly everybody will assume that the engine's performance will be at its best. It may be disappointing for you to know that it is not true. Mostly the new engines of vehicles are tuned at a lower level than their maximum performance capacity. Do you wish that your car's engine work at its best? The option you need to avail is ECU remapping.
What is ECU Remapping? ECU stands for "Engine Control Unit". It is termed as the brain of the engine. Basically there is a set of software programs a car's engine that controls the fuel system of the engine. The software is sometimes called as maps. If you have had the use of a computer ever then you will be aware of the fact that the programs of the computer can be changed as per personal requirements. Similar is the situation about ECU maps. These can be changed as per individual requirements. At the standard position, ECU maps are set to lower down the engine performance.
Why manufacturers do so? They are intended to increase the engine life in the worst possible situations. A vehicle is expected to be sold in any country of the world and may be used by a person who does not know anything about car maintenance. Similarly it is possible that low grade fuel is being used in the engine that may cause damage to internal parts of engine. That is why the manufacturers lower down the possible risk to engine by setting a safety limit.
The ECU safety limit is not for you if you are living at a place where roads are well constructed and fuel available is of high quality. This ECU safety limit is not for you if you know how to keep your car maintained and how to take care of your car.
Now come to the word remapping. Remapping is the procedure done by an expert; old maps of ECU are replaced by new maps that tell ECU that how to burn fuel and how to instruct the engine for its performance. New maps guide different parts and functions of engine including the pressure of fuel, injection of fuel as well as fuel timing. One can increase the performance of his turbo engine up to 30 to 40%. After getting an ECU remapping, you will find your car responding to your orders more quickly. You will certainly feel a change in the sound coming from engine. Your car will start running more quickly than before.
