P0172 & P0179 codes, Why?

Bah, still starts and idles like ***. Funny thing I noticed is the AFR on the EFI log and the AFR on the WB gauge dont jive. Sometimes as much as 2 full points off.
Might need a fresh air recalibration, either way it was still running like *** so I'm inclined to think the gauge was right and the efi input was screwy.

Looking at your logs the commanded AFR is rich and the wideband does follow it pretty closely in the first log. Didn't see any wideband activity in the second log, but commanded AFR was very rich at times. Do you have an older tune that was working well for comparison to see if anything was changed? Or just flash in an older known good tune.

Did some reading in efi. These tables seem to apply to E80 but I'm not sure what to set them to:
B3627, 28, 42, 50, 63, 64, 65.
They say for a single fuel composition that each column should be one number. I dont know what thay number should be. Any ideas? Wonder if this would make a difference?

My latest creations. See attachment. All the E80 tables I could find with 0/10/20/50/80 columns I set them to match the 0 (zero) column. If I understand it right, no matter what fuel composition the sensor thinks is in the tank it will react with the same numbers as if it was 0%, (which it is). So even if the sensor is shitting out, it cant adjust fueling because the cells are all set to 0%.
What do ya think?
Take a look. I adjusted all the cells listed in the above post.

I would think they would be altered slightly because of the increased cubes on a 6L. What do you think?
I guess I will try these settings. I'm still trying to tune around the E80 sensor. Seems like they are about $300 new. If all else fails I guess I will buy it, but it would really **** me off I hate flex fuel. It has caused me nothing but problems.
