Car control
The engine control unit (ECU) is basically a computer that controls how the engine works, a bit like a brain.
But the default settings or maps are not necessarily the best they could be, as manufacturers who sell their cars around the world have to take into account different climates, fuel qualities and laws when they program the software.
Car makers are also known deliberately to limit the performance of their cars through the ECU so they can release faster models at a later date, with just a few software changes and a much higher price tag.
Enhanced performance
Remapping is intended to make the most of your car by overwriting the ECU’s default settings with new software which can be programmed to enhance the cars overall performance.
It usually takes a couple of hours, and modern technology means it’s pretty straightforward.
Previously, the process was called ‘chipping’ and involved the removal of the main microchip from the ECU, which was then replaced with a modified chip.
Speed and power
If the remapping is successful, you should notice an immediate improvement in the speed and power of your car.
Some remappers claim an increase in horsepower of between 30 and 70bhp and in torque of up to 100nm.
The engine will also be more responsive, so it will be easier to overtake, for example. You might also find that you don’t have to change gear as frequently, boosting the number of miles to the gallon.
Before carrying out any tuning we first ensure there are no current engine issues by carrying out a full diagnostic check. We believe that driveability and reliability is as important as performance and therefore when you chose to tune with AutoElite you can be rest assured that your vehicle is in safe hands.
