Frequently Asked Questions
What does an ECU remap do on the MC-Cormick X8 255 PS?
An ECU remap (chiptuning) modifies the engine control unit software to optimise parameters like injection timing, turbo boost pressure and fuel delivery. On the 255 PS, this typically results in more power, better throttle response and improved fuel efficiency at part load.
