50/50 E-85 and 92 octane

[Gravy]

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.

Who is currently running E85? SHOW yourselves!

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.

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?

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.

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

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.

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).
