I want to experiment with E85.
Can anyone verify or add to my list (see pic) of what I'll need to change right away in the .bin to compensate for the AFR differences.
TIA

I would bump the pressure up, change the BPC and injector offset, but otherwise leave the tune alone and start it with a wideband also installed to see what I get. Stoich is a Lambda of 1.00, no matter if it's E10 or E85. The AFR values are just there to make it "easier" for us to visualize what we have for a fuel mixture. Don't take this to mean you aren't going to need to change things, but it's a way to see where you're starting before making changes to every AFR table in the tune. lol
I had a buddy that was running E60 in his untuned stock fuel pressure 350 TBI for YEARS without problems. He tried to run 85 but it was running out of fuel (this is before we had any idea people messed with TBI vehicles)
