What distributorless setup would be best to run for 93 lt1.. Plan on deleteing the factory ecm and going with Mega squirt.

 

The Opti optical sensor provides an extremely accurate cam position signal, hence several of the aftermarket ECU manufacturers have an interface for the optical sensor in lieu of any other form of crank or cam position signal. I use the Opti with my MoTeC ECU, and drive 8 LS1-style coils in direct fire.

 

I also use the opti signal with my Bailey Eng. LTCC coil per cylinder Ignition using 8 LS2 Coils.
