Remapping allows you to alter the performance of your vehicle by altering how the engine drives the car, however, it’s how the driver chooses to use the tuned car that ultimately decides what effects the ECU tuning will have.

​

If the driver chooses to change their driving habits to make the most of the increased power and torque throughout the ‘rev range’ and gear changes, then fuel economy can be improved. It really comes down to how the driver chooses to use the tuned car which decides how economic it becomes.

​

A car’s engine can also become more responsive, allowing the driver to overtake more easily. This can also cut down on the number of gear changes the driver has to make, allowing them to handle situations that require more torque without dropping down to lower gears. Again, this can help boost fuel economy if used strategically.
