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.

That is a really bad plan for a lot of reasons. I’ll list three: 1) uncontrolled backlash between the crankshaft and the distributor drive gear. 2) uncontrolled backlash between the distributor drive gear & distributor shaft that has the trigger points. 3) uncontrolled backlash between the crankshaft and the cam gear. There are many other reasons but you’ll encounter them as you research the details of the aftermarket ECU you intend to use. |
