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.

For cold start do you mean the non load parts of the fuel map??

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.
