Getting ready to tune for E-85

Getting ready to tune for e-85, should i take the entire fuel map and increase the offcet by 30% Or Just the load part? And then aim my afr (Wideband set to gasoline) to 12.1?

I would start by adding 30% across the board. When I did this, my AFRs were about 1 to 1.5 points higher than with gas. You'll also need to add more fuel on top of that for start up to help cold start.

Supernet -- I am really curious as to how E85 works for you.
Which injectors are you planning to use?

I am also really interested in the drivability. Keep us posted

Sorry, you'll have to ask someone else because I tuned my with a Power FC. I can tell you that to improve cold start, I am at almost 50% more fuel than with regular gas.
