Crank Sensor

Posted this in fuel/air too, trying to increases my chances lol.....my apologies.


I have a TBI LA360 with a non-stock compression ratio, need to take the timing control away from the PCM. To do that I need two separate signals, one to trigger the ignition, one to the PCM so it will trigger the injectors. The factory dizzy is a 5v trailing edge square wave with a #1 reference, I want to replace it with an advance type, and I also want to use parts that are available at just about any parts house, no having to wait 3-5 days for mail order replacements.

Considering a '92-'95 5.2 Magnum flex plate and sensor. Anybody tell me the voltage and type of signal the OBD-I Mag sensor puts out? It's a 3 wire sensor, not sure if it's 5v or 8v, the #1 reference etc.

I've spent hours digging the net, the MS site, the MSD site and others until I'm cross eyed, can't seem to find the specifics of the sensor signals to compare the two system's inputs.
