I can send you my current flex map if you like, just don't use it on your car as it might / will not work lol.
other than that, it's pretty straight forward.. use the compensation table to dial in more timing and fuel based on E85 percentage, not much is required on the fuel table as it assumes a blanket 30% more fuel. I did have to add a little at peak torque but for the rest of the ta le fuel was 0.
However I did have to add 20% more on cold start and 8 for warm start.
