I'm getting my car tuned for E-85 next friday!

[lozanoa11]

ive always wanted to do this. ide also like to see how this ends up. alot of mejiers has e85 in michigan. but in Illinois its hard to find

[SoulTerror]

The Meijers in Bay City and Saginaw both have E-85 pumps.

I did durability on E85 cars. There is a reason why the fuel lines and rail is differant

yup

please listen to him ^^

i am going the e85 route my self once i get the jack stanfs from under the car.

hear is a site to find a 385 pump in the u.s www.e85refueling.com

just go under e85 pump near you its one of the blue boxes.

the rummor that e85 is very crosive . I will dry out rubber and pit alluminum. their is a guy that has ran e85 for 9 mounths and has not seen any piting or crosive signs.

It's NOT a rumor. Stuff like that doesn't show up instantly.

Well good luck with your project it's always good to see people try new approaches and new ideas with their cars. Good luck and hope it works out great.

yea like others have said here there is definitely a reason cars must be "flex fuel" certified. Just because some one has done something and gotten away with it doesnt mean its a smart risk. If i was going to run E85 (and i have looked into it) i would be taking all of the necessary precautions to avoid screwing my car up. The reason for doing it in the first place is to save money on high octane gas, is it not? Risking extra repair costs seems kind of counter-productive to me.

Anyone know how to figure out how much the Octane will bump up from 93 octane if you add 1-3 gallons to your tank?

simple math ratios i am calculating that 3 gallons will give you 101.6 octane... but i have 0 confidence in my simple math because that doesnt seem right.

you can't do that. E85 requires a differant A/F ratio and flex fuel cars have a sensor that monitors type of fuel to control the tune

[transampimp]

you can't do that. E85 requires a differant A/F ratio and flex fuel cars have a sensor that monitors type of fuel to control the tune

So adding a gallon or two to a full tank isn't going to help any?

At the very least it might help clean out the fuel system if you add a bit?

[LSxDreamer]

For the people that are worried about the corrosiveness, I am going to switch to stainless steel fuel lines and upgrade my fuel rails eventually but right not that is not in the funds and this is about the only time I can borrow my grandfathers truck for awhile to get it tuned in Indiana. The tune and the trip down there is going to take quite a bit of my funds, but once they get back up I will be upgrading as it permits. I am not too worried about it corroding anything too fast.

But for now I am going to enjoy the new smell of my exhaust.

Oh and anyone that would like to chat with me more about it once I am running it I will be at the M&G.

[DETROITMUSCLE]

good luck and post results asap.

air/fuel will be off.
stoich for gas is 14.7
stoich for e85 is 9.7
the car will run lean

OK, Well I got it tuned to day for both 93 octane and E-85. Here are all of my specs, I am going to make you guys wait and have you guess what you think my 93 and E-85 octane numbers are because I am going to bed. 3 hours total sleep in the past two days with 9 hours of driving, I'm tired. I'll do a big long write up tomoorrw with a video. But i will say that I am very pleased!!!
