anyone here done an E-85 tune on their truck yet? it's just now poping up around my area.. and it's a little bit higher octane correct? any down sides to it?
E85 Tune?
- Thread starter Tooloe

Do alot of research before you decide to go that route. E85 can be an awesome affordable alternative to race gas (105 octane and mant other benefits), but tuning is alot different than gasoline. Contrary to popular belief, all newer cars have to be made to handle ethanol (All of our gasoline here in the midwest is 10% ethanol and has been for 10+ years), so very few if any changes need to be made to handle E85 usage. There have been studies done with no changes to the vehicle and cars going 200k+ miles on E85 with zero issues.

My understanding is that E85 has lower potential energy than gasoline, therefore to get the same performance, more fuel needs to be pumped in. You may need larger injectors, etc. to make it work right.

If it's anything like the new 4 stroke engines on boats stay far away from that shit....it tore up all the rubber lining in my gas lines on the boat! Not to mention needed all new filters and royally effe'd up my engine's performance!

Unfortunately where I live there are 4 gas stations and all of them use E85, so I am forced to put it in my truck...... So far I have had no problems.... I am not thrilled about having to run it only because that $hit leaves some nasty moldy residue on and around the filler door. And it is still a new concept and I really don't need it effecting my truck. Like I said so far I have had no problems but then again I don't put more then 2k miles on my truck a year..... :dontknow:

I thought the same thing with my boat after 2 years of using on 10% ethanol...dead end cruiser said:
My friend with a smaller 115hp 4 stroke was liek man it's clogging all my shit up, i told em it's all bullshit and didn't think it affected anythng....I was like nothing happened to either of my engines 225hp's...boy was I wrong
I did my own service...don don dommmm....fuel filter's were loaded with a thick white color residue all on the bottom along with pieces of fuel line....same in the secondary filter.....
I then decided to remove the fuel lines and holy shit is all I could say... the complete inner lining was melting away...it reminded me of the pictures with viens getting clogged up...I pulled all the lining out of the fuel lines with a hangar and it did not look good...
I just pray the same thing doesn't happen to our fuel lines..:dontknow: Would not be a pretty pic with that happening in our trucks..check your filter to be safe when you get some free time!
Do a google search of fuel filters ethanol!

Yea, I heard of this happening with boats. I really need to look at mine. So where are you supposed to fill up these days? Everywhere is 10% OR what can be done on the older engines? :dontknow: I heard that there was an additive we can add to the gas on boats.

I heard the Sta-Bil stuff is pretty good...Go to a local West marine or BOW and they have the good stuff there in cases...walbert said:
The best thing to do is replace fuel lines with the type that are used at the gas pumps, like that good year stuff...I just ripped the lining out of mune b/c thats the only part getting eatin:dontknow:
I would check b/c it is a serious thing on boat engines, there's even a class action law suit that was started of you search it on the web...
BTW a lot of marinas on the water now contain 0 ethanol for this very problem!

A couple viper guys in orland o use it and have had great performance gains with it. Plus you can buy a 55gallon drum down there fairly cheap and it doesnt go bad as fast as gas also

You know it...:rock:SANTEEN said:Haha. Stop being cheap and buy the non-ethanol fuel at the Marina. Cheap bastard.
Like a damn $1 difference btwn raod and water fill ups:marchmellow:
There is a reason the pumps have a warning on them not to use it in a non flex fuel vehicle....you are asking for trouble. The truck may run fine but are probably slowly frying the engine. Flex fuel cars have a sensor in the fuel line that detects the amount of ethanol in the gas and adjusts the tune to compensate.
I asked my tuner (Torre w/ Unleashed tuning) and he said it takes a major tune job as you are just not adjusting WOT settings...everything has to be adjusted...plus you will probably need larger injectors.
Lot of people around the forums saying you dont need to do anything...E85 runs fine....lot of people running it w/o issue....it gives more power, etc, etc........................make your own choice....I have too much in my truck to try something that I have been warned about...

Yes,
Ethanol is an oxygenate and although it has less b.t.u. value than pure gasoline, acts as a mini-nitrous setup (even with a 10% blend), as the extra O2 helps the fuel burn more completely; which is exactly what nitrous does.
I've been using a 10% blend (pump gas blend, 94 octane) in my SRT-10 for over 4 years now (60,000+ miles).
Unfortunately, even with a 10% blend, the O2 sensors detect the additional O2 and mileage drops as more fuel is added to compensate.
The mileage has dropped in EVERY vehicle I have tried it in.

Some of us lightning guys are running straight E85 in our trucks as a cheap alternative to C16.
One, its extremely cheap compared to C16.
Yes you do use more fuel, but compared to costs of race gas, its worth it.
Detonation is near impossible to achieve on E85. It can happen, but I have personally only seen it happen on one truck... and that was during a test tuning session to find its limitations.
You do need bigger injectors, fuel lines, fuel rails, and wiring to the pumps.
As well as a completely new tune.
for instance for my E85 tune, we have to drop the 60# injectors, and go up to 80# or possibly thinking even 100# injectors.
The Dual 255lph fuel pumps is not enough, so a triple setup was required.
Stock wiring has to go.
Also the stock fuel rails do not flow evenly enough, so Aeromotive fuel rails were required as they flow the most.
I wouldnt run E85 full time, only for the track and race applications, then just switch over to 93 octane for DD duty.
The third pump can be wired in via a relay to only come on during WOT applications.
