Ok here it goes I have a simple setup GSR on nitrous and a VAFC after getting it tuned when I spray it will throw a check code 3 for MAP sensor, and occasionally it will do it all motor but that is like once in a blue moon. . . Any ideas I have changed the MAP and it still does it and all wiring both engine and AFC is correct??

 

sounds like it is reading a positive manifold pressure and throwing the code. i dont know if on nitrous applications a missing link is needed but its wortha shot.

this guy dont know awhat he is talking about, how muh fuel are you pulling, or adding, sometimes if you add or pull too much it will throw a code, get rid of the afc.

 

Re-check your wiring. If the problem continues, look into un-installing the vafc & get your self a chipped obd1 ecu solution.

 

wiring is correct but why would i get rid of the afc. therefore getting rid of my tune and using a chip that will have less then half of the tuning capabilities of an afc???
