e85 fuel

[oldman_tau]

so i tried putting e85 on my 1g and ended up choking/stalling. so i drained it and put regular 91 instead. did it damage anything on my car? thanks in advance

No , you just need to get big injectors, fuel pump and a tune to run e85 in a dsm, or any car at that. Please update your profile with your car's upgrades so we know what mods you got. This link will give you all your info on e85 http://www.dsmtuners.com/forums/newbie-forum/59040-alternative-fuel-e85-ethanol-corn-gas-e70-beginner-merged.html

lucky him , you will be fine you can change your fuel filter if need be. The reason it died and spuddered is the demand of fuel that e85 over how much pump gas uses. The stock tune on your car and injectors are not where ready for e85, maybe with some 880cc injectors atleast and a walbro 255 with ecmlink tune, or customer burned eprom, or black box ecu flash from my1gdsm, then you can run e85. Just keep reading up and learn about it you will be ok and your car is fine. Just keep it on pump gas for now until your ready for that. A rather stock car is not really needed for e85, maybe when you want like 380+whp.

So you just pumped some fuel you know nothing about into your car? WTF

It requires a decent amount of modification to successfully run E85. Fuel pump, injectors, tuning device, ect. Car should be fine if you got it all out.

Thanks man! really appreciate it. it ran a lil better but still not like before smooth sounding. maybe its residue or leftovers. when i drained maybe 1.5 gallons left of e85 then i put $20 of 91 octane. hopefully after i consume eveything will be ok. i learned my lesson..


il try to update my mods.

yeah my fault...i think it still has less 1.5 gallons then i put $20 91. im just trying to consume it hopefully it runs fine again.

Yeppers .. E85 might have higher octane due to the alcohol content, but the BTU output of E85 is so much lower than regular fuel makes one wonder if the conversion is worth it.

Real thing about starting to use E85 in an older system is that the fuel is so corrosive that it begins to loosen up things in the tank and bring it forward to the filter and plug it up after awhile.

got it! i might as well replaced my fuel filter tomorrow. thanks!

Your brother's car may have been flex fuel compatible. Tune, lines, injectors at least all need to be replaced. Like previously stated, it has a nice octane rating but lower energy output, so more is needed.

+1 change your fuel filter. E85 does a good job of breaking up grime in the tank.

Even though almost all fuel has "up to 10% Ethanol in it", you need significantly more fuel when you run e85. Stoichiometic AFR for Gasoline is 14.7 vs. ~9.8 for e85, so you need somewhere around 50% more fuel for e85 (you don't run at stoich but its an easy apples to apples). Flex fuel vehicles have a sensor (an expensive one) that detects the mixture and compensates the fuel accordingly. Depending on the time of year/location in US, what's marketed as e85 can be anywhere from e70 to e90 (less ethanol in winter).

Take some of what you read with a grain of salt in those threads... Not everyone speaks from experience or provides the most accurate info. Shouldn't be to hard to make a decision on what is right or not from everyone talking in those though.

Fuel lines are not a requirement... . Nice to do. But, there are plenty of cars that make decent hp that have been on the stock lines for a long time with Zero issues.

On paper It may come out to close to that... . But in the Real world in most cases depending on the blend it comes out to about 26 to 33% more fuel.

Good starting point would be to take your injector size and multiply the size by 0.67 and use that as the base injectors size.

As well there are some newer less expensive sensors that Most new GM cars are running. It's about $70-80 vs the older one that was $250+.

did fuel filter fix it?

 

[boost97gst]

you just tried to run a super lean afr . Sounds like you didnt get far so im sure absolutely nothing is damaged.

Lots of very good info here!

 

[oldman_tau]

thank you very much for the great help! it runs ok now

Careful on the fuel filter removal. the top bolt is a SOB to get off and if you try to loosen it too hard itll actually start spinning in the mount. after 1 or 2 spins it will bend and snap the hard line attached to the bottom of the filter and that line goes all the way back to the fuel tank.

best thing to do is put a wrench on the bottom bolt while you loosen the top or maybe tighten the hell out of the mount... either way risky business cause that line runs all the way under your car and to your fuel tank which is not cheap to fix (trust me I made that mistake) but of course I went with 6 AN line... figured might as well go big daddy if im already there.

 

[oldman_tau]

thanks man, i had a hard time taking it off on the 1st time. luckily it didnt break any and this 2nd time its not that hard anymore..

Very true, was just giving a E85 101 you could say. That's intriguing, I didn't know the price had dropped so much from the original flex fuel vehicles.

Ya, GM was using strictly O2 feedback for a while to save cost I think over the ethanol content sensors and having issues IIRC. Which Might have prompted going back and the newer less expensive sensors... .

It's surprising really how many GM OE cars you can just add those sensors to and the Stock ECU can use it with a little work and enough injector. Though there are also quite a few car that they planned to make FFV and already have the mapping already and dropped it just because of things like EPA issues with cold start, et cetera.

They have it easier than anyone else as far as making there cars true FFV's and not just a Dual map setup like most people. That is the real benefit of using the content sensor most people can get away with not much of a change from E70-e85 as it it's tune on a high content it will richen up an be on the safer side.

It's going from gas/e10 to high blends that really gets you... As the OP found out.

Anyway... .

I agree, its amazing how GM can seamlessly go back and forth between fuels on their new flexfuel models. Big pump, big injectors show room stock? Nuts.

That means.. If you boost it and run 93, you'll never run out of fuel! >.<

Just to elaborate, I did not post that for people to buy anything. I only put that there for the reading material/educational purposes.

they are some much that goes into e85 I cant believe some one would just dump e85 into their car
