I guess the only good news out of all this is the fact that I really haven't seen the power out of this thing that I should be given a proper AFR.

Well, I sprayed brake cleaner (highly flammable) everywhere and I didn't hear one bit of difference in the idle. My EFI live doesn't do the blackboard (dashboard B) in real time? At one point my STFT's did go to like -10. I'm attaching the log.

neither do I. If I switched to display A (the gauges) it reads just fine. Click on B and nothing?

Ok, went out again. Got dashboard B working. Had the laptop in the engine bay logging. Sprayed brake cleaner everywhere. Nothing. No change in idle, STFT's remained stable. wtf.

What are normal values for the LTFT and STFTs? Should the LTFT's always be close to 0?

I clearly have a problem as under load on the highway the LTFT's would be between 9 and 11%

LTFT's should be as close to 0 as possible...
