Acceleration (Except Wide Open Throttle)

NOTE: For Wide Open Throttle (WOT) operation, SEE OPEN LOOP MODES OF OPERATION.

PCM INPUT:

Powertrain Control Module (PCM) recognizes an abrupt increase in throttle opening, (TPS voltage increase), or drop in engine vacuum, (MAP sensor voltage increase), as a demand for increased engine output, to accelerate vehicle.

PCM OUTPUT:

PCM increases injector pulse width to accommodate increased fuel demand.
