$0D TBI to MPFI conversion, how is your idle quality?

Not real sure about that one, are you running a MAT or IAT sensor? The PCM shouldn't be changing much if it has no way of knowing what the ambient air temp is? You might try moving your 02 voltages around to see if it needs more or less fuel while its doing this.

7060s have no provision for MAT or IAT, I have everything I need to swap to a 7427 so I CAN have a MAT, but just for my sanity I'd like to make the OEM ECM work before I swap to another. I've fooled with the mean o2 voltages at idle from .150 up to over .530 (noticeably lean to noticeably fat) and I can't seem to get that small bit of vibration out of it.

MAT is next on my list as well, I'm getting too big of swings in BLMs from hot days to cold days. Partially my fault I assume as I divorced all the heat riser equipment.
