Purchased a 123 ignition for a D-Jet but due to the difficulty of finding D-Jet parts I have decided to go with an aftermarket system. Probably a silly question, but could I use the FI firing triggers from the distributor for a crank position signal? Thanks in advance.

My mustangs tbi could care less about position of anything but the throttle (and a bunch of temp and pressure sensors). The computer does play with timing but really only to set the idle. And it knows that through the ignition module on the dizzy.
I bet you could get away with it since firing the cylinder is going to be determined by the distributor. If you keep it bank fire, timing the injection pulse need not be perfect and if that is the only thing the system is using the crank sensor for ... |
