E85 Blends

[blackrosenova400]

I thought I would post this link for anybody running e85 regarding winter/summer blends

Good info! I'm moving to arizona or florida below 29 latitude!

Can anyone tell me if the good blend is out yet, and where to find it?? Im trying to get my car tuned on monday, but i would like to do it on the good blend. Unless it doesnt make a difference??

I'm guessing it's still e70 here, but that's all I've ever been tuned on, it's still awesome. I wouldn't worry about getting a specific e85 tune vs e70, at least for a daily driver.

[blackrosenova400]

The easiest way to do it is to tune it with the best blend, then let it run rich when it goes back to the crappy blend.

It'll be more prone to knock with the winter blend though if you get it tuned on the summer blend. It seems like the few gas stations I've asked don't always follow a calendar or a timeline. If they don't sell a ton of e85 in the summer/spring, they aren't going to swap it out/order more until most of its gone. I would assume the same goes for winter blend.

[Shane@DBPerformance]

You might knock on the worse blend though, it you are tuned to the edge on the best blend. It runs richer, because they are adding in more crap gas, so it's going to be lower octane than the good blend.

Most of the stations around here were E70 until the end of May, I can test the ethanol content, if you bring in some samples.

Here is another good chart, at the bottom of the page.

Someone was telling me about some place south of town that sells Actual E85, E98 and other race fuels, by the barrel too. Might be worth checking into if your looking for it, Otherwise unless your running over 30psi I doubt you would have knock issues even with E70 anywase.

I was going to look into it, but I don't have a place to keep it. My friend might though.
Please let us know if you find out where. I figured some co-op.

Yeah, if only I could remember who was telling me about it...

Ive been testing ethanol content with this,

Anybody else test e85 ethanol content? Ive been reading 60% everywhere with this tool!

[asshanson]

60%? Shit, I better write to the state about this, the pumps say minimum 70% ethanol!

I should have found out what % alcohol I was running when tuned in April.

[goodhart]

I used one of those the whole time I ran e85. I've been hearing of lots of people reading super low as well...

[Nartanian]

Man that's garbage. At what percent does E85 because equivalent or similar to 93 octane pump gas?

It should have been 70% just about everywhere in MN. When it switches to 80-85% the car will lean out 10-12%.

I tested the Kwik Trip in Shakopee and it is 62% roughly right now.

I'll have to get a clean sample of E98 from John to validate the tester.

[Shane@DBPerformance]

If anyone wants to bring some samples to the dyno day, I have a digital tester we can test them with.

[Revobasher]

I will bring a sample.. I need to get my Zentronix ECA hooked up!

[scheides]

FFS 62%?
