I wouldn't put too much effort into it. E85 doesn't have enough benefit for n/a cars to deal with all the inconveniences of running it...
I considered it for my 4 liter, but decided against it.

Agreed, It would just be nice to be able to retune it myself as I make changes etc... completely un needed and overkill, I think it's something with the Orange, makes me a little crazy...

You guys would be surprised with E85 gains even on our .... ops I don't own one anymore .... even on GT3s.
Remember that we are dealing with a high compression engine and yes it will work.
Back in 2008-2009 we tuned a GT3 running E85 with the stock ECU, and in a bone stock car only with a sharky track exhaust at the time the car dyno'ed at 401WHP on the same dyno I do all my tests. This was a gain of over 20WHP only with track exhaust and the tune. I still have to dig the videos, where the GT3 was getting killed by a E60 M5 and after the tune, the Porsche would leave the M5 in high speeds.
Also after that a 997.2 GT3 (Black) running on E85, and I can say that the tune wasn't even close to maxed out (timing wise).
I started using Ethanol back in 1995 in my on cars as they were / are readily available at the pumps, where I come from.
