Re: 50/50 E-85 and 92 octane
I had to laugh the other day, i know it's not the E-85's fault. But it made me wonder....
I put one gallon of E-85 into my tank thinking, i'd start with one and work my way up. Well, after i filled up i drove around for a good hour before going home. From there, i was heading down to the north St. Paul area from Saint Francis, aka, a fair drive from home. The car was a B!TCH to start and i got a check engine light for the remainder of the trip. Car ran funny and didn't like to idle, it was surging more then normal. I know it wouldn't be the E-85 at that low of a mixture, but it made me think.

Re: 50/50 E-85 and 92 octane
I'm using 100% E85 with 1600cc injectors and DSMLink. It's working great! Except I can't get the 1600cc to drive and idle as well as the 720's that were in there. I'm thinking of switching to something smaller. I just need to figure out how small I can go.

Re: 50/50 E-85 and 92 octane
What kind of IDC's are you getting with E85 and those 1600's? Did you get teflon O rings and such? If so, where did you find them and how much were they?

Re: 50/50 E-85 and 92 octane
50/50 mix for over a dozen tanks. i can tell a difference between regular 92 octane gas and 50/50 mix on the SMIC BIG time. Pulled like crazy, when it was normal gas i would heat soak and knock. Could feel the car pulling timing. After i threw a FMIC on the car and the car drives like a dream. No timing pulled, and even wanted to attempt the above mentioned idea on E-85. But with no fuel mods it'd be just asking for a blown motor.

Re: 50/50 E-85 and 92 octane
What is the best way to adjust the computer for the 50/50 or straight E85 mix? Do the people who are running this just have dsmlink?
I am guessing I can't just put half and half in my tank and expect it to run well.
However I thought one still needed fuel mods to run 50/50

Re: 50/50 E-85 and 92 octane
FIC has 1150's now, I am thinking they might work well. I will be making the switch to E85 this winter and those are what I am looking at right now. I might have to run a little higher fuel pressure though. We need something in the 1300cc area that idles decent.

65% IDC at 41 lb/min. It's running way too rich though.
I'm using whatever O-rings come new on FIC injectors. |

Re: 50/50 E-85 and 92 octane
Holy shit. So basically if you go E85 you pretty much have to get 1000cc's or 1600cc's huh. Are you still on stock lines, rail, etc? Thats on the stock turbo too isnt it?

I have a supra fuel pump and 1G fuel rail (because the 2G rail dosesn't fit with a Buschur AFPR), the rest of the fuel system is stock. I have a 2.4L with a PTE 50 trim. You definitely wouldn't need 1600cc injectors for a stock turbo (1000cc is probably overkill). I went with them because some people reported having luck with them and DSMLink. I'm going to try find the largest injectors that DSMLink can idle as close to stock as possible (780's worked perfect but are too small for my needs with E85). |

Re: 50/50 E-85 and 92 octane
Oh, and I also have an electronic fuel pressure gauge with warning lights and a fire extenguisher for safety.  Because even though from doing research I'm pretty confident I won't have issues with E85 eating parts, I'm prepared for the worst. |

Re: 50/50 E-85 and 92 octane
Ok, thanks man. Thats funny because that is the same setup I am toying with... a 2.4 with a 50 trim and E85. Would the 1000's be able to support that 50 trim?

I'm not sure. I think they're going to be pretty close to maxed out. I need to see how much I can lean the AF out, then calculate what size injectors I'll need off of that. |

Re: 50/50 E-85 and 92 octane
What AFR are you running at? Do you think a 255 will be able to keep up running E85? How do you like the 2.4/50trim setup?

Re: 50/50 E-85 and 92 octane
You could try an injector driver box to run the 1600cc in true peak/hold mod. That might help smooth them out a bit.

Re: 50/50 E-85 and 92 octane
No comment on the evo... It likes pump gas.
On the Talon I ran a 50/50 mix, it worked a lot better and cheaper than 110. I wouldn't get any knock at all flowing 54lbs per minute or around 26psi on the pte GT3561. I would knock on the 111 at bobby and steves or any power 110 fuel. I hope to have Shane tune it before the snow falls.
Chris I run the FIC 1600cc injectors and they idle great and part throttle excellent. Better than the pte 780cc injectors I ran before. I'm on the link. My o2s would cycle just fine.

Re: 50/50 E-85 and 92 octane
Jim, did you do anything to the fuel lines to prevent corrosion from the E85, or does thinning it out prevent that? The 50/50 mix sounds like it will be the way to go for me.

I am using the stock fuel system, I have been running e85 since last year and so far so good. I planned on replacing the lines but honestly with the 50/50 mix I am not worried about the fuel system. I have gone over it twice since I started running e85 and will give it another once over before I sell the car.

Re: 50/50 E-85 and 92 octane
Ok cool, i will try the 50/50 tmrw. I have 650cc injectors i bought them oversized so i could try e85 on my E316g i have never gone over 65% duty cycle in wot so i think i'm safe.

With 50/50 you will be fine. Do it up. |
