Professional Tuning File Service

Tuning Files and ECU Remapping Tuning File service

The software used to tune cars and upgrade a vehicle’s ECU is known by a lot of different terms. Common phrases such as tuning maps, mod-files, good old-fashioned chip tuning files, or remap files are all quite common. Although not all accurate, they all generally mean the same thing, a software file of control maps that dictate how a vehicle ECU  (electronic control unit) and the engine it controls, will react when the driver requests something to happen.
