Tuning an engine for better performance or fuel efficiency by reprogramming the Engine Control Unit

ECU :
The engine control unit (ECU) is 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 car’s overall performance. 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. But things have now moved on.... Speed and power When the remapping is successful, you will notice an immediate improvement in the speed and power of your car. With a possible increase in horsepower of between 30 and 40bhp and in torque of up to 80nm. 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. |
