Okay, once again I'll post this. Does anyone have HPTuners in SE MI that would be willing to do a quick log for me???? I need a quick datalog to look at some items....My MAF, upstream and downstream O2 and my STFT and LTFT..... I think I have figured out my vibration, but instead of throwing $200 in parts at it (again), I want to see if I'm right. My car is suddenly pig rich and I'm not sure why..and it goes to below 12.5 AFR at 1k RPM.... So I'm thinking my vibration has something to do with this, but need a datalog to make sure.
