1.3
Operation
The GC90Ci GoldCruise consists of a compact EM, that’s connected between the
electronic accelerator pedal and the engine-control–unit (ECU) of the vehicle.
The EM “manipulates” the ECU and controls the relationship between the driving speed,
throttle valve position and fuel injection time. The manipulation occurs by varying the
output signals of the accelerator pedal. This means that the signal structure in the ECU is
not altered at all. Because the accelerator pedal is learnt to the system, the GC90Ci
GoldCruise or speed limiter can make optimal use of the available engine power.
