Not going into closed loop
Not going into closed loop I have started datalogging the car and have been picking up knock on my naturally aspirated setup. I have come to realize that my pcm never goes into closed loop even after 30 minutes of driving and i was told this might be the reason i am getting knock. I have been using datamaster and I have a 94 z28. Anybody have any ideas as to why im not going into closed loop? The engine temp is pretty consistent from 185-190 due to my 160 tstat and fans set to turn on quicker.

Only DTC code im getting is MALF33: MAP high which started appearing after I adjusted my valve lash. Unfortunately I don't have a wideband. It's interesting you say that though becaue I got a dynotune with a fuel pump that was crapping out at 4800rpm and it was tuned partially. I have not had the chance to bring it back after I installed my racetronix fuel pump kit. All my logs have been after the racetronix pump install.
