How to run your LS1 on E85

Not sure what you mean by it being "re-used"? Because plants absorb CO2? Well to make it, you have to harvest (as in cut down) 100's of thousands of acres of the plants (corn fields) you are saying are going to 'absorb' the CO2 produced by this ethanol.
Didnt read the rest, but I assume you read this stuff somewhere. Check the motivations of your sources. You are probably quoting BP Gas's website spin.

Ethanol is the VCR BETA format of fuel. Cool idea but won't last. Actually, its not. BETA was better than VHS. It just wasn't as popular.
Just tuned the procharged ls1 gto on E85. It put down 598rwhp @ ~6500rpm running incredibly rich. What are you forced induction guys running lambda wise. I ran out of dyno time, but put the car on the street and leaned it out a little. It felt like it picked up a lot of hp, but the butt dyno is misleading. It's going back on the dyno soon.

Was this on a stock bottom end??? Those are really good numbers man...

How much injector am I doing to need to withstand 800rwhp on boost?
I'm turning up my kit this year and am running dual 255lph pumps (hopefully thats enough), just need to figure out how much I'm going to need at the end of the fuel system to take full advantage of this fuel and not lean out too early. 60lbers would be ok for gasoline or race fuel, but e85...i'm assuming something like 84lb'ers?
*EDIT- Also, has anyone found out a solution to quickly toggle between seperate tunes so as to run a gasoline tune, an e85 tune, and a race fuel tune on the fly? I heard something about a Diablo Sport Predator being able to do this.

So I'm pretty good in that I understand most of this, and I've been searching for this kind of information for months... so I've got a few questions I hope yall can help me with:
1. To run E85 on an otherwise stock motor I need the capacity to push 30% more fuel. I've got an '06 LS2 GTO and have no idea what the stock injectors flow. 30lb/hr?
2. Would I need to use a higher output fuel pump? I'm not sure what my GTO's stock pump flows. I wouldn't think a 255l/hr would be needed.
3. My limited tuning experience is with SCT XCal and twEECer - does HPTuners have the function of easily switching between tunes? For example an E85 tune and a regular 93 oct. gasoline tune?
4. Would the engine even run right on 93 oct with 42# injectors? [for the alternate tune]
Runn, great post! A ton of helpful info on these pages!

I just talked to a buddy that used one of the newer generation FAST injection pcm's/systems for his TPI car. anyways he was telling me he has the function to switch between like 4 diff. tunes at the flip of a switch. I told him of this thread and the other thread. dont know if he looked into it yet. he's into tuning his car himself, and this would be ideal for him since he has a 383 cid high compression small chevy.
the stock eng. would run fine with 42lb inj.s, but that whole tune would have to be totally customized to match those injectors.

Uhhhhhhhhhhhhhh! I have neen running e85 since cam install and dyno tune!
When i first tried it the car ran like **** , but my tune came with the handheld predetor so after reading the long term lifts i noticed they where at 25.0 on both banks . Then i checked the mv at wot on the o2 sensors and they where at like 10 - 30 mv . So i adjusted the injector slope to -25 % and increased timing at wot up to 31 degrees . I am no way shape or form saying this is right thing to do , but the car runs like a champ zero spark knock on a 100 + day with 70% humidty and in 6th gear at 30 mph . My mph is only down about 2 or 3 mph so that is not to fing bad to me and the stuff is only 2.21 a gal one tank full in my 2002 camaro with tr224 cam headers all bolt ons still get me 265 + miles so not looking real bad fellas . I have read in this thread about the lines being nylon coated and plastic tank and viton seals , witch my car has all so i am gonna just run it. I put 9000 on since the cam so no problems yet!

Well I live in Colorado and it gets pretty cold here. And I never had a problem starting. Nethier did any of my other friend's who have switched over had any problems. I think if you want to run E-100 then you might have some problems But E-85 you should be good.

My Personal experiance is +4 degrees across the whole range. Then stock timing with a 150shot. On my 92 Eclipse I was able to run 3 degrees more timing and 10psi more than what I was currently running for a total of 29psi. The biggest thing I found was you run out of fuel pump real quick.
just thought I'd update this thread from awhile back. We fixed some of the issues (leaking boost etc) and the car made 645rwhp on a stock bottom end E85 car. It's a daily driver and has been that way since May with no problems.
I think there are only a couple of good things about e85, you can run a higher compression motor on the street (run more boost if turbo/blower), and I make tractor parts so we are making tractors like crazy. Otherwise its just a marketing ploy.
