* EDIT: http://dodgeram.org/tech/dsl/ISB/Vp44.htm this details the VP44 operation it doesn't incorporate a needle lift sensor instead it varies timing based on the output of the pump shaft position sensor and crank position sensor.
"A reference pulse that marks top dead center (TDC) of cylinder No. 1 is sent from the ECM once every pump revolution. By comparing this reference pulse from the ECM to the position signal from the speed sensor (IAT), the fuel pump control module (FPCM) can reference the pump's position in relation to the engine's position. This allows the fuel pump control module (FPCM) to adjust the pump timing to compensate for minor position differences between the fuel pump shaft and the engine camshaft."

the first generation cummins 6BT 5.9 uses a bosch VE pump which has a SOI timing advance built into the pump. the injectors have no electronic feedback to the pump even some of the later VP44 pumps have purely mechanical injectors. the system uses a hydromech advance you don't need feedback for that just some careful tuning to get it right. SOI can be controlled as an independent variable with some experimentation. the stock engine uses a mechanical advance with a fixed advance curve dependent on rpm it doesn't need to know the SOI for the electronic governor to work. all this would do is allow for more SOI timing advance and to be able to change the advance curve in real time.
