LT1 optispar crank trigger

Massimo Narini

Recommended Posts

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?
