What is ‘remapping’ – and is it worthwhile?
Did you know that you can boost both the power and fuel economy of your car in about 30 minutes, simply by altering the settings on the engine control unit?
It’s a process called ‘remapping’ – and it’s all the rage among petrolheads.
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.
