So I'm guessing (I would italicize "guessing" if I could) that this might have to do with my global fuel adjustments. Currently, my global fuel is sitting at -50.8% . That's a good bit off from the calculated value of -52.63% than my FIC 950's should be at/around. Now I adjusted my global fuel over the last few weeks to get my VE max cell values down below 100. Really a cosmetic adjustment, but was it really...? Could it be that I've adjusted my global fuel higher and enriched my actual AFR's while in turn, artificially leaned-out my AFRatioEst?
This theory seems to fit and it's easy enough to test. Yay again for a formula-driven GF adjustment spreadsheet that calculates the changes to the VE table cells. I'm going to dial my GF down to -51.6%, which gives me a max VE cell value of 100 (go figure) after everything is adjusted. I'll get that put in and we'll see what happens.
This is so much fun
