as I have done some more reading it is almost exactly the same as a Nissan 360 opto system, only with more inner slots for the 8 cylinders.

I am using a stock replacement MSD Optispark for my 95 LT1. The optispark uses 2 optical triggers:  - an outer high resolution ring of 360 evenly spaced slots used for crankshaft position -an inner low resolution ring of 8 slots of varying size that correlate to the different cylinders  Is there a way to calibrate the Link G4 Extreme to use these as the trigger inputs instead of a crankshaft position sensor and a cam angle sensor?  How would this be wired?
