ECU Chip Tuning
The most difficult concept to grasp for most people is that remapping is merely engine tuning, albeit that it’s being done electronically rather than mechanically. A chip’ is simply an electronic storage devices or EPROM which is located on a circuit board inside the E.C.U (the Engine Control Unit). The chip contains values in a hexadecimal form which the E.C.U’S main processor (another device on the same circuit board) can understand and use and control the engine.
