I'm trying to get this tune running right on my car and I have the check engine light flashing under boost both full throttle and part throttle. Full throttle afr is in the 12s and part throttle under boost is around 14afr. Pulled the plugs and all look good except for cylinder one. I cannot hear anything motor wise like detonation but the plug doesn't lie. Plan for the weekend is to get new plugs and swap injectors around to see if the detonation follows.
the setup is a 88 2.2 with the stock mitsu t2 ic and airbox with k&n filter and 2.5" exhaust with no cat and straight thru muffler. Have the fuel pressure set to 55 psi with the vac line unplugged an set the ignition timing awhile back. Don't wanna blow this thing up so any quick tips would help. Posting this before I bug rob about the calibration or eliminate the calibration being the issue. Is cylinder one usually run lean with a one piece intake? My boost is only around 12 lbs
