Anyway, anybody know where I have to adjust the TPS% for the PCM to go into Open Loop (OL)? I actually sat at 3psi and 15:1 AFR today until I let off the gas. If I give the pedal a quick stab it drops right into OL but, if I ease into it I can get up to 3psi before OL kicks in and the AFR drops into the 11's as it should.
So what table do I need to look at?
