A little help,I know some of you have done this. Can i use the ring on the back of the 928 motor with the EDIS-8 ignition: set up with cop or is there something that gets in the way? I have a little to learn here. thanks,Ray

None of the factory rings work with EDIS-8

It requires a 36-1 tooth ring.

I normally set up the ring on the front of the engine instead

these are commonly used as a trigger, front-mounted as suggested...
