Yes I was running 112 and changed to E-85 and so far
I went up 2 degrees but like I said it wants more, I'm
thinking I will be about 6 degrees above the 34* I
used for race gas... but I still need to test more

I haven't done a good back to back series of ignition timing tests... yet. I have been running the same 34 that I ran with race gas (flat top pistons, quench). On gas, my engine ran the same at 34 and 36, but slowed down at 38.
When I started with E-85, I did my first pass or two at 30 for safety, but then went to 34 and it was quicker.

33 on e85 and 36 on race gas.
I test this in engine dyno.
I was up on 38 on e85 and ther the power starts dropping fast. Backed down and it was the same power and trq on 36 and 33 so I run 33.
The VP motorsport 109 like the 36 better and made 10Hp more on 36 compered to 33.
This was on my motor i dont know what your motor like.
