First, I just rescaled the table as shown. I also created a couple tables with Fuel Mass on the y-axis, one measuring error between commanded AFR and wideband AFR and the other showing LTFT.

I used these error perentages to adjust the injpw by a corresponding amount. Then I uploaded that tune and reset adaptives. That pretty much killed the error I was seeing. 8% before the tweak became 1%. Now I'm kind of a perfectionist so I continued tweaking right away, but I think it's better to wait for the LTFT adaptives to gather more data before making changes. The error percentages up top under WOT obviously respond to any changes right away.
So that's where I'm at right now. This is the first car I've tuned so I'm figuring it out as I go. Take my suggestions with a grain of salt. ;)
