NO ECU MODIFICATION - Immediate return to factory settings at any time: The device operates entirely externally and makes no changes to the engine control unit (ECU).

HOW DOES THE GS2 CHIP TUNING BOX WORK? - Manufacturers often offer the same engine with different power outputs that are limited by software depending on the vehicle version. The GS2 Chip Tuning Box uses these factory performance reserves. The device adjusts signals from selected engine sensors before they are transmitted to the engine control unit. The ECU then optimises the air-fuel mixture accordingly. This allows the engine to provide more power - without mechanical modifications or permanent changes to the engine control unit.
