I checked my Chevy Fuel Injection bible (by probst) and he says that the knock sensors are not used in open loop. Having said that, lets fix the obvious things first and change out that knock sensor. On the tune, if the base tables are out then things will always improve when it goes into closed loop. I've been chasing the opposite situation this last couple of weeks where it runs great in open loop but like crap in closed loop - mine is an issue with the large cam messing up the O2 sensor readings. My point is we should scan the car to see what's going on in open loop and closed loop (Also see your PM's) |
