If I recall it's just fuel injectors fuel rails and possibly programming. E-85 is quite corrosive so many fuel systems don't get along with it.

Aww come on yall...

I LOOOVE E85. And so does my Evo lol. Cheapest race gas around if you ask me. (Sub $2 a gallon)

Like others have said though. It is very corrosive.

When I wanted to make the switch. I had to replace the injectors, (you need more injector since E85 burns quicker)., fuel pump, fuel sock, all fuel lines. And an E85 safe fuel filter. Basically all of ur fuel system needs to be Ethabol safe.

On top of that, you need a custom tune. You will need a LOT more fuel, and you can have more advance in the timing with E.

My evo made like 450 something to all 4 wheels on pump 93 gas. Switched over to E85. And that change alone netted me just over 500..

There is nothing more fun than spinning all four tires in a AWD vehicle lol.

I run E85 on everything else but my lawn mower and my 5.7L Ram (it's been under warranty so no modifications whatsoever to the powertrain) - the Ram's getting converted next spring.

Ethanol is only corrosive if the same fuel is allowed to sit for months and absorb water from the atmosphere. Methanol is corrosive but methanol isn't ethanol. I don't use E85 in the lawnmower because it gets put away seasonally and I don't want to have to fool with re-jetting the carb over how little fuel it really burns per year.

The reason you need more E85 injected than gasoline is because some of the liquid fuel is oxygen that you normally would get from the atmosphere. A gallon of E85 is similar to 3 quarts of gasoline and a quart of liquid oxygen. You're still burning the same hydrocarbon mass per horsepower you just also have to pay for some of the oxygen now instead of getting it all for free. But you don't have to drag as much inert nitrogen through the intake, past the valves and out the exhaust so you get a little power boost from that and from the high relative octane behavior of the ethanol. That's also why ethanol gets along with boost and high compression engines so well, less nitrogen (per volume of fuel) taking up space inside the combustion chamber.

It's not necessary to run a custom tune, exactly - there are kits sold specifically for this purpose and they don't touch your engine computer.

https://eflexfuel.com/en-us/e85_ethanol_conversion_kit

They connect between the computer and the injectors themselves and work basically like a reverb does on a guitar amp, adding just a little sustain to each injector pulse. As long as your injectors have enough bandwidth to supply sufficient fuel without going lean you may not even have to change out your injectors.

In America people are weird about ethanol but this is something done with hundreds of thousands if not millions of cars elsewhere in the world, it just plain works and all the spooky warnings handed out by people who haven't done it? Don't happen. You burn more fuel per mile (because now you're paying for some of the oxygen) and you get more power and a smoother idle - and if you have any interest in reducing your impact on the atmosphere it's a partially renewable fuel too - and every gallon you buy helps keep cheeseburgers cheaper since fuel ethanol production is a coproduct of livestock feed.

E85= Bad news

heh, OK but it's weird that on this page FCA says



Ethanol Flex Fuel Technology

  • Ethanol flex-fuel technology developed by FCA defined the world standard for flex/alcohol fuels

  • Flex/Alcohol technology enabled Brazil to become the only country in the world with a real alternative to oil-based fuels

  • Leveraging sugarcane-based ethanol fuels, the technology developed by FCA provides well-to-wheel environmental benefits

  • Flex-fuel will continue to be the central technology for Latam over the next years


Notably 3.6 and 4.7 Rams have been flex fuel from the factory since 2004.. :)

Ive had 3 vehicles I ran with e85 on stock everything, 06 GTO, 09 G8GT and 13 Mustang GT. Didn’t have any issues with anything other than lack of injectors in the GTO considering the car had cam and full exhaust hahahahaha.
all tuned by me. You have to wonder how most who have never ran e85 before, can spread all this bs about e85 destroying your full system and bla bla bla. Let me tell you again bla bla bla. If you want to run e85 make sure your injector duty cycle doesn’t exceed 90-92% at WOT. And make sure you can tune cold ECT startup fueling and if you don’t have the alcohol sensor that you can correct for E-XX alcohol stoich point in your calibration.if you have FI make sure you have enough injectors and fuel pump to supply constant wot fueling. Also you want to be able to tune engine timing. This stuff is not the devil it requires more attention to details.

I'm not discrediting you. Because you obviously have plenty of experience with Ethanol. But items like OEM fuel socks, and filters if there any, are not good with ethanol and degrade over time. Same with fuel lines.

But then again. Since chevy and ford are pretty big into flex fuel cars maybe all that stuff IS ethanol safe.

Just from my experience with a japanese car, they are only good for gasoline. And will eventually break down with time.

(Also. I understand people are talking about true flex fuel. With an E content analyzer. My car just runs on E85. No flex sensor)

It is not possible to make a material that is soluble in high concentrations of a solvent and not soluble in low concentrations. Since e10 is a normal and expected fuel, every material fuel contacts is necessarily ethanol compatible.

Cars in the 1950s with tree rubber hoses and cork gaskets might have a problem...

I wish I can tell you anything about *** cars and e85. I’ve been tuning since 2006 and have been around American high performance since then starting with the LS2 engine, playing with e85 when possible since then. For GM stuff that didnt come form the factory with the Alcohol sensor there is an alochol sensor you can buy and some calibrations are so ready for alchol literally a toggle switch to enable the sensor and calculations based from it. my 14 RAM has spark tables for PT/WOT alcohol but i don't see an option to enable an alchol sensor nor alcohol stoich, FA options etc, so more tuning will be required. Big 3 have been using this stuff for many years so their idea of longevity in the fuel system is perhaps assumed.

I have a 2011 ram 1500 5.7 hemi is it possible to convert it to e85 if so how?

You need to have a tune installed to take advantage of the extra ignition timing that can be had. Also your stoich ratios will be scaled for the ethanol. Fill the tank, load the tune Enjoy!

At the end of the day it sounds like more hassle than anything for a few gains. And I'm gonna guess if you Wana run regular fuel again you have to stop load your regular gas tune in and off you go again. If Ur not racing what's the point in the end I doubt you'll save any money at all....

Mixing E-85 to about 30% (more depending on injectors) has been popular for FI engines for a while.

It was super easy on the Kia Stinger with a JB4 because they had algorithms for E-85 percentages.

It’s much more to do with injector duty cycles. In a DI engine I’ve always been a huge fan of methanol injection to keep the valves clean and increase octane.

Straight E-85 will need a tune and for you to figure out if you need to upgrade things.

redline si-1 white paper pdf

We have seen something special happening with si-1, there will be a thread on it after a few weeks of testing. But if you are running ethanol blends, and most of us do, consider adding something to preventing rust. Stay tuned for Corey's thread on it with boroscope, anti rust is not the only benefit of this product.

I don't think anybody's denying that one can make more power with E85(HELL GM puts E85 HP and TQ numbers in the manual when running E85. I believe it was 28 HP/33TQ extra!) What most people want is the option to buy 87/89/91/93 with no ethanol without having to pay the E0 premium) 87 no ethanol around here costs .50 cents more a gallon or just slightly less than premium. Just give us the option without the extra cost.

When I am looking for an extra bit of octane I will run another 10-20% of E-85 in my 2500 6.4. I also run Lucas injector cleaner which is supposed to help with corrosion due to ethanol. Been doing it for 3+ years now with no problems. However, I don't think I would want to convert it over to be able to run 100% E-85. With the drop in fuel mileage that you get, it barely pencils out to save any money.

They are two different products should milk and OJ cost the same amount?

Funny, when I got my 2017 Ram, it was a Flex Fuel motor (my first) so naturally I tried the E85. E85 is a bit cheaper than E10 in NY, but it burned much faster so I actually didn't save any money. I suppose I did my part to help the Iowa corn farmers...

What the hell does that even mean? I don't buy 10 plus gallons of milk/OJ a week..........let me guess you're one of those guys that's never had an ethanol related failure in a small engine right? I've literally cleaned tons of that brown crusty **** out of carburetors and it ain't pretty. We did just fine before ethanol and eventually it will go away.
