No matter how fast or sleek your car is, its performance and power are still limited. This is not due to any mechanical factor, but it is caused by the software which runs inside the engine control unit (ECU). This knowledge paves the way to vastly improve the power and fuel economy in just about 30 minutes by altering the settings of the ECU through a process called remap. Let’s understand its various aspects. There is an article from Turbo Dynamics about ECU tuning let’s take a look.
WHAT IS REMAPPING?
Most modern vehicles contain an ECU (or Engine Control Unit) that is effectively a small computer which controls how the engine works. Vehicle manufacturers de-tune the engine by setting the software on the ECU to default before sending the vehicle out. This is done due to the manufacturers having to sell their cars all over the world, this means that the software settings on the ECU must take into account different climates, laws & restrictions and varying quality of fuels. Vehicle remapping is basically the modification/replacement of the manufactures default software on a vehicles ECU.
HOW DOES IT WORK?
A vehicle remap replaces default software on the ECU, overwriting it with new software which can be programmed to optimize the cars overall performance. This is known as vehicle remapping because the ECU is essentially a program that controls how the engine works. When your car is remapped, the tuned software is plugged into your cars serial port (or OBD port) which then overwrites the engine map with the new version to enhance engine performance. The ability to flash directly through the OBD has brought the tuning industry on leaps and bounds, with constant development on the engine now being much quicker via the flash process, it has enabled Celtic Tuning to develop some of the best software in the world.
