And as a proof of concept I unplugged my cam sensor this morning and, lo and behold, the truck ran the same as always. No difference that my butt cheeks could feel, so apparently he's correct when he says it throws the PCM into batch fire mode. Since this scheme retains a distributor spark is unaffected. For reference again my truck is the 5.7 Vortec that he constantly refers to in his video running the 411 PCM. If you have a 96-97 OBDII car this literally only requires the PCM with an appropriate tune to no longer rely on the optical sensor within the optispark unit. For everybody else, swap out your crank pulley hub, timing cover, and add that 4X reluctor. They can be found on OBDII F bodies or on the myriad of 96-02 5.7 Vortec engines piled up in junkyards. I may actually look into guinea pigging this if it's something you're willing to entertain Al.
