also i am working on a 13.5:1 and e85 only. I have also heard that our (aussie) e85 is better than your e85 as it is derived from sugar cane and not corn, giving it higher octane. Whether this is true or not is another whole argument. However like you i am keen to see the results of the combination.
you will with a standalone as you can go pretty crazy with the timing maps, but you are right high comp and boost will see the most benefits
Yes, the aussie stuff is better, but like I said before it is much an advertising game. There are tons of pumps here that read E85, but they actually have a higher concentration of gasoline than they should. Prob just because of elevation. I wouldn't be surprised if the aussie stuff is better though.
You can go crazy with the timing maps, but I honestly don't think you will gain much power because of it. On 91oct at high elevation I tried changing base timing maps and I found that 19* base timing had the best results for top end performance with my JWT ecu and my setup. Increasing timing to 21* lost power, even though the engine never knocked.
You can only increase timing so far before you stop making power with it. But you know this.
I would like to see if there are any gains to be had with E85 on a stock motor, but like I said before, I am very skeptical that there will be any.
