Profile ignition pickup
Encyclopedia
Profile ignition pickup (PIP) is the term used for the signal sent from the Ford EDIS
to the electronic control module (ECM). This signal is the digitally modified signal that originated from the Crank Angle Sensor (CAS) in an alternating current
format. The PIP signal into the ECM is a squarewave switched at 12 volts and is the ECM's reference for engine speed and position. The PIP signal when received by the ECM can then be modified to take into account the ignition timing

Ignition timing
Ignition timing, in a spark ignition internal combustion engine , is the process of setting the angle relative to piston position and crankshaft angular velocity that a spark will occur in the combustion chamber near the end of the compression stroke...
