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 to the manufactures 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 manufacturers default software on a vehicles ECU.
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 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.
Many people say that ECU remapping doesn’t affect fuel usage, however this is not technically true because of the process involved in the ECU remapping more fuel is going to be consumed in order to produce the increase in power, if the car is driven in an enthusiastic way after the remap has been carried out then the fuel economy will not increase (and in some cases may decrease).
If however, the driver modifies their driving style to make the most of the increased power and torque throughout the rev range then fuel economy can be increased.
A good example of this could be that the improvement in torque produced by the engine after remapping means the driver no longer has to drop down a gear to maintain speed on a incline or may not have to change gear as frequently in traffic, All of these little things add up to an improvement in fuel economy.
We can also offer DPF and EGR solutions with vehicles with problems in these areas.
