agree with dicky
I bought pretty large injectors when performing my head swap to handle running E85 thanks to this thread, looking forward to your new tune and results.

Thanks guys! I just sent my logs to Vince to make some fuel trim updates. We are working on the three subjects below.
Idle
Increase in MPG (pretty low after header install)
Raw WHP
Once he is satisfied with the logs I will be hitting the dyno up. Just as a heads up I will be creating a new thread with the final results. I will let you guys know when the threads up. We need more exposure to the final outcome (to much work to not share with everyone)
I just want to prove that you can have a reliable E85 tune with light bolt-ons with no fuel system upgrades on a LS3. Just between you and I guys, it's looking awesome. Car drives really well and I have logged almost 600 miles since last week with this setup. No negative effects other than the drop in MPG and the two cat check engine lights. Once it's all buttoned up with the tune I'm going to run a few videos.
Video topics
MPG
0-100 MPH
Dyno
anything else?
Thanks!

Do a couple roll pulls. 0-100 leaves too much wheel spin on the table. 40-130 (if you feel comfortable and have a safe place to do it) is a good measure.
Also lets see some angles from the back with idle and light to moderate revving, kinda like this.

Not a problem.. This guy is cammed so it wont sound quite as good but, it does sound great. Once I get a tune update I will start filming!

E85 run after tune per post 151
I was able to do some time runs at Darlington SC during the winter and had several poor runs due to wheel spin that were at 12.0x @116-117 and the only clean run was 11.95@118.34 da was about 320 and car with driver on board was 3505#.

So what did the car put down?? Im sold on this mod. Got to get to the shop for a tune though. So how does this actually work? Let the car almost run out of gas on the way to the tuner with a gas can full on E85 running shotgun? Then fill it up after its strapped to the dyno?

When I switched my Grandsport over I ran down to a 1/4 tank, we fired the fuel pump and drained the tank (right at 4.5 gallons) swapped injectors to FAST 85 lbers (I am adding a supercharger later) and my tuner did the base tune. We dumped in 10 gallons of e85 and started dynoing. It took him 5-6 pulls and the air fuel was spot on, bumped the timing 2 degrees in the midrange and it picked up 20 rwhp and 10 ftlbs of torque. That would be 23 rwhp on a dyno jet. What it really cool is because the fuel burns slower is the whole car feels smoother, some of the cam buckedy buck is gone and you can actually put the car in 6th gear and have it pull form 1000 rpm again (It has a mild cam vs stock).
He is now working on a program that will allow the end user to switch back and forth like a true flex fuel vehicle and we (my tuner and my Grandsport) are suppose to be on Two Guys garage in Oct along with HP tuners promoting the E85 switch. Also be on the lookout on http://www.masterenginetuner.com/ Dan is going to have a step by step article on the E85 transformation on my car including tuning and dyno run video's.

there's a stand alone out already that allows you to be a true flex fuel vehicle in the sense you don't need to swap maps but dump in supreme and ethanol and the system does the adjustments, pretty sick little setup but so is the price but you get what you pay for so yea.
my biggest issue is finding some one who tunes e85 vettes, everyone I talked to do far isn't a big fan. wonder what a good flowing 1 7/8 header+3" exhaust/cam/ported heads and intake put down, obviously e85.

Maybe I'm missing something, but I don't understand what would be complicated about the tune? Adjust stoich to reflect the 9.xx of E85, adjust the timing/fueling tables to take advantage of the higher octane and let her eat.
I'd expect around 550whp with a heads/cam E85 LS3.

thats what i thought but they said e85 wasnt in the immediate area BUT ive ran e85 since 2007 and have accumulated 4, 5 gallon jugs over the years so bringing it would be an issue.... im going to try and take advantage of east texas muscle cars 1500 dollar cam deal and throw in e85 in the mix.
question and im not sure if im even right i just thoguht about it, would changing the head gasket or milling them down raising the compression a little equal to more power? i think i read some where on NA cars running e85 higher compression yields better results?

not to bring down your hype, but you got the car tuned. so thats an easy 20-25rwhp in itself. then you gained about 10-20rwhp on e85(still good). your injectors are prolly close to being maxed out as well. So when/if you do bolt ons you will need injectors as well if you plan on staying with e85....e85 does wonders for F/I not so much for N/A.
this is a good option for people who don't want bolt ons, but want more power.
what was the duty cycle of your injectors anyway, on e85?
I'm glad someone did it though and glad you posted.

Same feeling here! Gasoline has more btu's and is the better fuel.
Plus your mileage is down compared to gas. But more power to you!
