E85 Compatibility

Postby Mattr66 » Mon Oct 15, 2007 9:30 pm

Well folks I think I have a solution for you guys wanting to run on E85.

Is there anyone wanting to try out an E85 program for their vehicle (with no promises)?

In the December issue of 5.0 mustang magazine thay made 668HP on a supercharged stang.

Here's a video of a non flex fuel truck that did it anyway for over 100,000 miles:

As long as your fuel lines and rails are steel and not alumnium E85 should work for you. The only way you will screw anything up is if your injectors and or pump are already at full capacity.

Lake City and Tallahassee have one... so does the kennedy space center, but i don't think they will let you pull up at the pump....

I think the tune I did for you will already do it elvato..... The 03 expedition 4.6 has the adaptive already set-up properly if I remember correctly, I know the 5.4 does. I can check for you tomorrow.

Yea, I check for stations around here. The Lake City and Tallahassee ones are the only two public ones in Florida for now.

if you have enough leftover injector and fuel pump capacity i don't see why not......

Do you have any idea how much pulsewidth you have in reserve with your current combo? Or you can just watch with a wideband.....

My only experience with ethanol enriched fuel was back in the mid 80's when they sold a 10% mix almost everywhere. I was in the Volvo repair business at the time and had a hell of a time figuring out why cars I had properly tuned and tested with a Marquette exhaust gas analyzer would not run and start properly. I finally figured out those cars were running gasohol as they called it back then. The way I tested for it when I tuned the cars was by turning the fuel filter inlet side down in a clear coffee jar. The fuel from the ethanol cars would be full of silver marbley looking stuff and after sitting it would settle out in the jar to be about 25% sediment and 75% gas. I assumed at the time the alcohol was eating the galvanized coating off the inside of the gas tanks. I tried to have the Florida Department of Agriculture and Consumer Services test my samples to confirm but they said they knew it was causing problems and were just waiting to the federal deadline to run out then they weren’t going to allow the sales of the product any more.

If ethanol eats up aluminum it could have just been eating away at the fuel filters but it sure had a lot of stuff in them just to be from inside a filter.

Either way the cars would tend to surge and you could crank on them for 5 or 10 minutes waiting for them to start back up after sitting.

In my opinion this ethanol fuel is best left for cars that are constructed with known compatible components and tuned to run the stuff. Just throwing the fuel in a car that wasn’t built to run E85 is a chancy proposition even with a tune.

Love E85, great for boost found that you have too run 40% to 45% more fuel up top

my supercharged expedition loves the e85. I estimate it makes another 30 or so horsepower than 93 octane with 9lbs of boost not intercooled.

I can also make the tune completely "flex" if you have a way to manipulate the octane wire to the PCM. You have to run more spark even over 93 octane tuning otherwise your mileage and power suck!

EFI has made me lazy when it comes to tuning...LOL

I remember the days when i was screwing with emulsion circuts in carbs and whatnot to do what i can do now with a few strokes of the keyboard......

Let us know how it works.
