What is a Chip Tuning File?
A chip tuning file refers to the software used to remap the Engine Control Unit (ECU) of a vehicle. This software file adjusts various engine parameters such as fuel delivery, ignition timing, turbo boost levels, throttle response, and more. A properly created tuning file improves performance, fuel efficiency, and sometimes drivability.
