Acceleration Mode
WARNING: This page is about a different car, the 2003 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
ECM monitors the changes in the Throttle Position (TP) and MAF sensor signals in order to determine when vehicle is being accelerated. The ECM will then increase the injector pulse-width in order to provide more fuel for improved driveability.
