The following is from the SERT online help file:
MAP - Manifold Absolute Pressure
This sensor provides input signals to the ECM and reacts to intake manifold pressure and ambient barometric pressure. Intake manifold pressure reflects changes in engine speed and load. Ambient barometric pressure reflects changes in atmospheric pressure caused by weather conditions or changes in altitude. The ECM uses the inputs from this sensor to help calculate how much air is entering the engine.
Again, good write up..

Thanks, I have updated the thread with the correct information.
