holley only allows it for gm ls and ford coyote to bypass the cam sync after firing up. it was one of the first things we considered. few weeks ago car ran a few clean no error passes. thought we had it dealt with. then it just showed up again for no apparent reasoning what so ever. must be rf interference but from where...still hunting it down but out of ideas. seperated coil wiring from crank sensor wiring. cam sensor is what errors all the dang time but its all by itself more or less. ive checked the cam wheel on the cam sprocket and it isnt loose either. exhausted of ideas honestly. enough so ive not even touched the car since getting back from sct.
