Anyone ever put one of these on an LTX?

You would need to put it on a DFI sytem or equivalent aftermarket computer for the signal to be interpreted correctly.

I have one on my "l98" setup that feeds into a Accel DFI computer.

The crank trigger is TONS more stable at high RPM and is dead nuts accurate. No vibration from the cam to crank to contend with or timing chain slop.

The Electromotive Opti-Eliminator was a crank trigger system for the LT1.
http://members.aol.com/InjuneerZZ/Emotive.htm

It was designed by J.C. Hyde, the same engineer that developed the Delteq system.

The Opti-Eliminator was OK on a batch fire system, but didn't work on sequential fuel injection that started in '94.
Edit: The Opti-Eliminator had no camshaft position sensor.
