James is correct, SAE corrections are sea level and 70* to have a constant

Mine was changed to correct the tune. In the end, that curve is just part of the fuel calculation. I autotuned my ve table on like a 65* day. At that point, the 65* bin cannot change and the curve hinges off that point. So my curve should work, you just need to shift it up or down the graph to make it work if that makes sense

I ended up just scaling the standard curve. I think by 25%. It seems to work much better now. Much more consistent AFR on cold mornings and during the day. See how it goes I guess in summer when it warms up.
