Subject: Re: tuning questions by bam on 2013/5/4 14:57:10 I really appreciate the comments, feedback here, otherwise one feels lost in the woods!! I will try your suggestion on the PE, I was going to change it but for now I will leave it alone and do another data log first. One question I have is; why the two 02 sensors? My 08 Grand Prix only has one located back of where the two manifolds join into one. The timing, map readings, temp readings are all the same for both banks of the engine,if so then why change the fueling. I can still see the split BLM's (although I have not logged since smoothing the VE tables, they may have improved but I doubt it) I am thinking this is because of the hot cam (112 lobe separation) and the LT1 intake short runners?? If I am right the problem is enhanced by having 2 02 sensors which are always trying to compensate for the reversion in the intake and constantly fighting against themselves. Andy any thoughts, have you been able to eliminate or improve on the split BLM issue with these motors? |
