better yet.

There's so much false information about ethanol out there...here's a few:
The plants don't use as much energy as some would like to believe, and continue to get more efficient. E85 could be sold at <$1/gal and still be profitable.
Mixing ethanol would be fine, but you'd have to get your mix exact each time and have it tuned with that mix.
AFR will read the same. Your oxygen sensor will still read the same amount of oxygen when ethanol is at stoich (9:1)...so you'll be tuning for the same targets...no refiguring necessary
A few "perks":
Ethanol is produced 100% within our country with corn grown right here...I never understand why that means nothing to people. I would think people would be willing to pay much more for that alone.
E85 = 105 octane (and in my experience it seems more detonation resistant than that, and likes to run leaner)
E85 drys quick and clean (you can spill this on your hands and not even smell in minutes later...nice when you're using a fuel cell)
A few downsides:
Although it won't freeze, ethanol is very finicky in cold. A lot of fuel needs to be dumped in for colder starts
Tuning seems a little more precise. Your window of adjustment is smaller. Ethanol doesn't like to run rich.
During the cold months, some stations use a lesser content of ethanol (as low as 70%) in the E85 pump to help with cold starts in flex vehicles. If you're car is tuned on the 85%, it will just run a little rich, so it's not a big deal as long as you're a little conservative on the timing. However, tune on the 70%, and when it switches without notice you're running lean. This is something I just found out and want to look into further.
I've run ethanol in 10%, 20%, 30%, and 85% in a variety of vehicles. It isn't the perfect fuel, but nothing is.

Now that the treehugger crap is said.... as a fuel its fantastic for forced induction as it is high octane. Power increase with tuning is quite good, similar to that of methanol injection or better. Mileage will go down 10-30% depending on how you drive it.
IMHO, the big question mark is how your fuel system will hold up in the long term.

everything takes energy to make sir... if you want to stop wasting energy then life will have to cease existence.
in fact this arguement is so weak i'm gonna have to come with more... you think that oil refining doesn't cost energy? you think drilling for oil doesn't cost energy? you think building that 1 billion dollar oil rig out in the middle of the ocean doesn't cost energy?
oh but debateably the energy extracted is is more than that which was put in... ok. by that argument we should be using nuclear power... that doesn't have any side affects. but at least that's better than what we're doin' now.
i don't see how taking energy from the sun with plants is somehow less efficient than taking energy from ..... wait... the sun, from... plants........... isn't that what oil is? oh but oil is compact energy processed by nature... well what happens when nature isn't processing it fast enough anymore??? oh that was the concern to begin with huh???

E85 burns cleaned, unlocks more whp, and cost a little less per gallon.
A 15% decrease in mileage is that bad when you think about all the gas guzzling V8’s that we already lay the smack down on at the track.

Just got done having a tune done on my Honda with 1.8L motor and GT turbo. Made 552 whp at 22.5 lbs of boost on E85 (available locally 1.5 miles from my house for $1.79/gal. I got 16mpg going from Dallas to Houston (car never reached operating temp) it was 25 degrees last nite. I made 516 whp on on C16 on the same boost. The tuner, Tony Palo, of T-1 Race Development in Dallas is tuning an EVo 8 with a GT35 soon with E85. The evo is getting 1600cc injectors and an additional fuel pump.
