Loren, your right on the money. I listed the basics, but, yes, there is more than 3 minor functions of the ford distributor. On my T-bird, from how I understand the system, power tothe components upon turning the key switch, that activates the fuel pump for a moment, shuts off, then you turn the key to the start postion. The distributor, when the starter rotates the engine, activates the ignition, tells the computer the engine is rotating, and rpm measurments, and crank, or cam location to know which cyl is firing, or upon an intake stroke,,, the MAP sensor helps start up timing by a vacuum signal, aided by the air temperature switch, and water temp switch for cold starts, and cold running charatceristics. Throttle position switches, compensates fuel rate pressure, so it takes 2 sensors to tell the computer rpm, and throttle position to know how much timing the injector has to remain open to feed the cyl. O2 sensors read how rich or lean the exhaust gasses are to also help regulate injector timing. Im not for sure if allthat happens in that exact order, Id have to go back to my service manual to be exact,,,, but that is some of the basics on how the input sensors of the EEIV system assist the computer. The output devices are control units, that is the sensors and switches, the computer controls to regulate injector timing, ignition timing, and rpm timing related issues the fuel system has to monitor to compensate. What these guys want to do is, convert the IH trucks with the old downdrafts carbs, to a more modern fuel injection, but, which system is the easiest to adapt? Chad
