​​​​​​​this may sound stupid but without an ethanol sensor like flex fuel vehicles have from the factory how does the ecm compensate for differences in alcohol content? Testing at the pump has shown that most if not all E85 isn't 85% and varies as much as 20% based on winter/summer blends especially up north. I may be dumb here but that seems like it would cause rich/lean issues.....

We test here, it stays pretty consistent at 70 percent. If it varies to much I will rewrite the VE and save it for that blend and switch back and forth. A hassle if you drive a lot but luckily I dont.

This is exactly correct. I chose the ID1300's, and should have gone for the 1700's.
I tend to learn things the hard way.
The 1300's will meet my goal though, just no room to spare on straight E85

my shop had a guy who bought ID1000s then ID1300s and eventually ID1700s and he really wished he had gone straight to 1700s so that is what recommended I do.

They also said I will need to test my E85 when I get it and I can add some E98 to it if need to be bring up the level if it is too low.

​​​​​​​yea see that would drive me crazy. I'd love to do it because the difference in fuel cost but the stations are kinda far from me and I'd rather pump it straight in the tank. I will be driving it on a low boost setting on the street and I'd love to just run one fuel between low and high for simplicity and cost but not looking realistic for me... I'm on a factory ecm as well so switching up tunes won't be that easy for me either

Without a sensor I assume you just have to test it and adjust the tune manually. The sensor makes everything easy. I’m up north and ours is still 80%. I made my power on 73% though so I don’t get caught up in that much.

Are you still running that t56?

Seems like it would be easier, and make more sense to just leave a little "safe room" in the tune to account for variation. Just seems like a bit of a hassle to be trying to find and blend E98, were saturated with e85 where I live.... but wouldn't have a clue as to where to get E98. Hopefully the place you're using isn't going to tune it to the ragged edge.

I am still running the T56 for now, will be changing that out to TH400 in the best future. My shop doesn't tune like that, they are a little on the conservative side which is good.

If that bitch ever hooks at 1krwhp.....RIP t56. Your car is going to be retarded fast when you go th400.

That's exactly what my shop said. Told me I'd be faster at 700 with a TH400 than I am now she when we up the boost on E85 it's going to be nasty fast.

When you go 400, keep your console. Imo the auto consoles are trash. Here's how I did mine here in the pics. And it will make you're life easier staying away from the shifters that make you pull levers and pushing buttons just to shift. Quicksilver is a solid peice.... and doesn't really have that racecar look to it. At 1krwhp, if you can keep it together and on the track..... you will be WELL into the 8sec zone.

Looks nice. Doesn't look too modified either, kind of keeps the stock look. I like that.

Even without the flex sensor you can run most systems in closed loop with a WB02. This will account for the minor changes in ethanol content. 10% variations were common here and my ms3 handled it no problem without the flex sensor. I run the flex setup in another car and it's pretty sweet for the 30$ worth of parts it took to install.

Also If you tune it leanish on e85 it will richen up with lower alky percentages. Lower the ethanol content the richer it will become, so you'll never "lean out" if you tune it on your highest percentage.

​​​​​​​you have brought a very valid point about running a high alcohol content for tuning and it can only richen up from there! Can't believe I didn't think of it like that. 100 octane is $7.45 110 is $7.95, E85 is 20 cent cheaper than regular, seams the route I'm taking! 40min drive for me though...

I am buying 6 or so 5 gallon jugs and filling them up in my 4 cylinder beater and taking them back home, my drive is about 40 minutes as well. That way I will have about 2 tanks worth and will just refill them once a month or so.

I run 2 450's and the bosch 2200's. Anything above 22psi i start losing pressure. Im about 60% DC at that point with e60-e70.

Just curious, but are you using Tytech?

If you are asking me no I am using Dynospeed.

Its best to NOT store E85 or any Alcohol fuel in plastic for extended periods, it will water saturate. Alchy likes lined metal storage, you can get refurbished 15 gallon drums at most chem supply houses. Or they also sell nice stackable 5 gal lined steel pony cans.
Buy the gasoline decal from a fuel distributor for it to pacify the DOT, and it makes a drum a legal fuel container...
