i live in nc, here,they are building a big plant here,i am all for e-85 it will put alot of farmers back to work, and we wont have to import more oil ,both of my cars will be running e-85, when more places have e-85 pumps around me

but the bene's are great. I know when I get around to my iroc project (race car) it will run on E85. and unfortunatly my 95 will be dismantled and returned to stock engine over the winter to be sold at a normal price. so makes no sense to mess with that.
here in Sweden.
98 octane gasoline cost 12sek/L = $1.68/L = $6.36/gallon.
And 104 octane E85 cost 8sek/L = $1.12/L = $4.24/gallon.
and i though gas prices were high where i live!

I have been very happy running E85 in my TBSS. I have been running it this way for about 3 months now and have had zero problems except for finding E85 stations on rare occassions. Luckily almost all the Meijer's around here now sell E85. Anyways, I have recorded a solid and steady 15% drop in combined MPG runnig the corn. At the same time, E85 has been consitantly 18-20+% cheaper than 93 Octane in my area. Even with my pathetic tuning skills I have enjoyed a .2-.3 second reduction in my 1/4 mile times. All this plus my money is going back to Midwest farmers instead of Middle east wackos makes it more than worth the effort to change for me 
E85 is helping farmers, but also the oil companies. It takes a lot of diesel to farm. I think they should work more on Bio-diesel. Making ethanol also requires alot of electricity, which in the U.S. is mostly produced by burning coal.
All of that aside, I do believe in the performance possibilities of it.

right, but thats jus for now. but once we start to make this e85 stuff work, Im sure the farmers would much rather burn fuel in there farm equipment that is based off the product they make dont you think? so possibly thats in the future too. a corn based deisel fuel. you'll never get the big oil companies out of all the profits, but if they have to buy the corn from us to do it, then they open refineries here to make it, that keeps some of the profits here, and employ's more americans to do it, even if its run by some middle eastern owner who keeps the big profits.

Verdad Gallardo can someone tell me if this correct. essentially all i have to change, to run E-85 is the air fuel ratio for stoich in my calbrations. the computer uses this for all of calculations for air fuel mixture. i have a bigger pump and injectors so thats covered.
That is about it. You will need to re-tune of course.
I can't wait to try E85 on my new build up (details in sig).
When I had a carb on the car with a procharger, it seemed to
like 20% more fuel at light throttle and 40% more at WOT.
The midrange torque was much better, and since the motor
was built at 10:1 compression, I was able to add 5 degrees of timing.
I noticed that even if you tune E85 WAY rich, it still runs fine.
This is nice to help buld a little better safety into the tune.
I would suggest adding pumps capable of 50% more fuel flow
at least, because you know that you will be turning up the boost when you see how well the car likes the CORN JUICE!
I could have the car running in the garage all day and not reek of
gas fumes afterwards.
After running a few tanks of E85 though the motor the plugs were so clean
that I could have pulled them out and returned them to the store!
Good luck!

thanks for the info. the pump is walboro 255, but i just checked some old logs and the 42# injectors are at 150% duty cycle on gas but they run real rich up high. but im thinking 60's maybe 70's as replacements. i have the ve tuned now for gas, so i will need to do it again. man that sucks i just got finished tuning everything.
thanx again guys i may just try this without the new injectors to see how it will work

so i just got done waisting my gas for the e-85. i put it in changed the stoich value to 9.799. the car runs but not with out issues, but i expected that. what i didnt expect is that my efi live doesn't seem to be able to except the new stoich values. all my logged data is way off, even though my lm1 reads 8.9-10.0 afr my ve correction factors are 1.44. i am running ol sd so the ve table is commanding very close to what it should be, at least at part throttle. does anyone have any ideas on how to change the settings in my software, or anyother software. since i have efi live hp tuners and ls1 edit thank you 
well, the easiest way would be to run an injector constant that basically allows you to run the car in a normal condition. So, set the a/f ratio back to 14.67 and change your injector constant until the shft's are next to zero. Your VE table shouldn't have to change much, maybe a little around torque peak as you will see an increase in power there, otherwise, the car will run the same.
I hope this makes sense for you.

so basically change the injector flow rate table until i get the desired afr
edit: i think i found the problem the lm1 was set to output in lambda not afr. its to late to check now. i have to leave town tomorrow for a week, so i wont know for sure until then.

Correct, you did not change the phisical aspects of the engine, you just changed the fuel. The only thing outside this that you may need to do is some fine tuning to the VE table to get all the STFT's close to zero. You can now also run more spark without fear of detonation. You should be able to run MBT at all places. This means a more effiecient engine which will equate to more power!!! 
i will actually be going to tune on a dyno next week. but i have not had it on a dyno since before i put on the blower
i'm not sure how accurate the calculators are but i took my best trap speed 111.8 and the weight of my car 3920 and came up with 427 rwhp. uncorrected. correction foctor for that day is 1.24 so an estemated corrected rwhp is 529.48. so we see what dyno says next sunday. hopfully i can get tuned well before hand so there will be less to do while i'm there.
