What? I have no idea what this means... "America's gas" means "gas heavily subsidized by Uncle Sam whose production is incredibly wasteful"?

That said, there are more productive ways to produce ethanol, but we are just not implementing those for the most part right now.

And all you guys haven't wasted a ton of money on your vette MODs! I don't care about all that crap! If demand goes up from a bunch of crazed Corvette owners running it religiously the market will drive up the efficiency.

Results don't lie for the naysayers
Did you dyno before E-85?

I go out of my way to buy 100% PURE gasoline. No E10/E85 crap for me.
Back in 2010 I said bon voyage to a bunch on another forum when I got sick of them detuning TECH. I mentioned how I basically saw a PTM developing, which, was on a local BMW tuners WEB site, and how great that would be on a Vette. They said, you don't need that. Six months later it showed up on the ZR1, and the Cup tires would never been able to go on without it. I said you guys are in the fifties!
Interesting how we kind of regressed back into the 50s.

Anyway, sinking your heels in when it comes to TECH is not only a waste of time, but, is going to net you on the wrong side of issues.

Would just rather have the billions spent subsidizing ethanol be used to research battery tech or fuel cell membranes. Something that has a viable end game (ie not combustion). The faster we can transition to the bulk of transportation to electric power the less time the lawmakers will have to whittle away at displacement and power.
The amount of water that gets attracted to E85 isn't remotely enough to rust anything it would touch. The only way for that to happen is to have a metal gas tank. Water won't make it through the rest of the fuel system, even if the car is parked for a while because the fuel lines are air tight. Water would somehow have to creep up through the fuel pump and through the fuel lines.

Other than that, it wouldn't be possible for anything to rust. The lines themselves are stainless steel. The fuel would combust leaving nowhere for the water to sit in the combustion chamber and as long as the fuel pumps have no parts that can rust (which they don't), there's nowhere for rust to start.

The idea is even more unlikely than the idea that SOMEHOW enough water could accumulate in a tank of E85 to hydro-lock the engine. (Another obviously untrue myth.)

Don't know if you follow NASCAR, but they have gone to E20. All the NASCAR tracks have underground storage tanks but when they went to E20, they discontinued using the underground tanks. They bring in a semi truck with the E20 premixed and fuel the team's gas cans directly from the fuel tanker. I wonder why?

I am sure he dyno'd before but it wasn't a no change after. You cannot take an LS3, drain the fuel and drop in E85.

At a minimum, the car needs to be retuned. It may need bigger injectors because you need to inject more fuel due to the lower energy content of E85 (~25% less BTU in E85). You can run extra timing but you are not going to get 25% more HP just from extra timing.

A bunch of the FI guys are switching to E85 on their heavily boosted cars because it allows them to run more boost. That gives them more HP.

Yes, I did however, the pulls where a few hours apart due to having to get all the pump gas out of the tank. Either way, the results were very shocking, and the car has been running perfect as my DD for over 13 months now. I have a really awesome detailed thread on my E85 experience (Track times, mods, MPH, reliability, fuel economy) in the C6 section if you are interested on researching it.

Either way, I will be happy if the C7 doesn't come with E85 as a standard fuel, because my ECU developer is on standby to help me have the first on the streets with the gas. He was the first to crack the ECU on the V6 camaro running DI, and the new Cadaliac ECU's as well. He is very confident he will have it tuned swiftly. He is buying a 2014 Silverado to crack the ECU, due to the truck using the same computer as the C7

So what did you have to change besides the tune to get it to run E85?

For those of you who have made the switch to E85 what is your before/after fuel mileage?

nothing at all my friend - Fuel in tank, flash the ECU with the new tune.

I don't know. Do you wonder why?

It's well known you cannot store ethanol for prolonged periods of time. You think that has something to do with rust? It does not. You're not going to rust anything in any car with E85 that wouldn't get rusted with any other fuel. My point being that there's nothing that could rust between the fuel tank and the engine. And there wouldn't be enough ethanol in any fuel tank in a Corvette to attract enough water over 6 months to make any sort of difference.

Can you attract a lot of water with a tank of E85 sitting in a car that hasn't moved for years? Yes. But if you did that, you're a dummy because you shouldn't store a car without a fuel stabilizer anyway.

There, you made most of my point. This ethanol junk is being shoved down our throats by politicians trying to get reelected. When we make something that is less efficient and causes us to use more oil, food etc. it's folly. Yah, lets keep spending more resources and money for nothing. Great idea.

honestly if you drive a vette gas mileage really shouldnt be the high note of the sale. but yes mine has dropped. it does take more ethanol comparied to normal gas. the the perks out weight the less mileage. the benifits it does for the performance are by are more important then just a little bit of more fuel burnt.

im just getting at that it is made in the USA. not shipped over. you guys cry about the subsidized ethanol what about crying about we cant drill for oil in the USA????
