e85
Close...Senses ethanol contact in the fuel. It mounts inline to the fuel line before it even reaches the injectors.

When e-85 is cheap I run a 60/40 87gas/e85 mix. I calculate it to be about 95 octane. The monte really opens up and runs smooth. Plus the smell is addictive. I only have a longer/slow start on really cold mornings but it is easily fixed by adding more gas. When I run higher than 60% e85 the traction control goes off at 100% it throws a bank 2 lean code. I have ran this mix for the last 20,000 miles 38,000 total. I do notice more power and my mpg stay right around 22-23.

Thats fine, I was merely trying to understand.
Not just that but he's now running incredibly lean. Stoich for that mixture is somewhere around 12.7 but his computer is thinking 14.7 is stoich. That's a full 2 points lean. A word of advice heavyft, stop doing that unless you want a new engine sometime in the future.

Are you 100% on that? Every thing I read about it said that any car that was designed to run e10 had the coatings to protected it for e85.
With a 10% ethanol content, you don't need any protection. That's why it's in regular pump gas and can be run through much older vehicles.

Corrosion
E85 can cause damage, since prolonged exposure to high concentrations of ethanol may corrode metal and rubber parts in older engines (pre-1985) designed primarily for gasoline. The hydroxyl group on the ethanol molecule is an extremely weak acid, but it can enhance corrosion for some natural materials. For post-1985 fuel-injected engines, all the components are already designed to accommodate E10 (10% ethanol) blends through the elimination of exposed magnesium and aluminum metals and natural rubber and cork gasketed parts. Hence, there is a greater degree of flexibility in just how much more ethanol may be added without causing ethanol-induced damage, varying by automobile manufacturer. Anhydrous ethanol in the absence of direct exposure to alkali metals and bases is non-corrosive; it is only when water is mixed with the ethanol that the mixture becomes corrosive to some metals. Hence, there is no appreciable difference in the corrosive properties between E10 and a 50:50 blend of E10 gasoline and E85 (47.5% ethanol), provided there is no water present, and the engine was designed to accommodate E10. Nonetheless, operation with more than 10% ethanol has never been recommended by car manufacturers in non-FFVs. Operation on up to 20% ethanol is generally considered safe for all post-1988 cars and trucks.
I read it on the internet so it has to be true. Lol
But seriously I’ve got a couple of friends that converted over to e85 a couple of years back with little more that a tune with no issues.

Still, I would like to know if GM uses different fuel lines and fittings in the Flexfuel equipped vehicles.
Thanks for posting that!
E85 is 105ish octane. With the turbo and E85 its defiantly makes more power, and my tune is way off. With a n/a car I’ve heard you may make a little more, but gas mileage is going down. I went from 17 mpg to 13 mpg. (but the tune is off and I’m not driving it on the highway as much) So if E85 ain’t significantly cheaper I would waist your time.
So maybe a stupid question but Racing fuel is E85?The reason I ask,is there a place near by that sell I think 101 oct.On thrusday I planned on doing a mixture of 91 and 101 1/4 (101) & 3/4 (91).I've been asking around but no solid answer,any help?
