thats odd, considering its the same cam sensor as the vortec. they require the CMP offset to be +- 2* from zero. and its real touchy. I'll play around with it when I get it running and see what I can find, I'm just too OCD to not set it to something.

anyone know what the CMP Retard offset (vortec) PID is actually physically monitoring? (i.e. does the crank signal play any role in it? if not we could still use that one.)
