All gas staions in IL E10?

[PANDA]

Do all gas stations in IL sell 10% ethanol now? Should ones stoich ratio be set at 14.1:1 compared to 14.7:1?

I would think ethanol enriched gas is better for performance, but it has a effect on MPG.

Discuss.

I have filled up all over the state and have not seen anywhere in Illinois that does NOT sell 10% ethanol. I have to get to Indiana or Wisconsin to get the good stuff!

MPG suffers as does track performance with the 10% crap.

Stoich for my E10 setup is at 14.3 and my PE AFR is 11.3. Seems to be working well right now..
Also don't buy from Citgo that crap sucks.

I haven't noticed a change in fuel trims from gas station to gas station so i don't think it really matters... You guys go way overboard with how particular your tunes are. We have things called fuel trims that can easily make up for +/-5% change in how much ethanol is in our gasoline without affecting your tune settings of this i am sure.

Pretty much everywhere south of the Chicagoland area has a gas station around that sells 100% gasoline. Had a ton of them down in Carbondale when I went to school down there.

I don't think I've ever been to a gas station in the Midwest that isn't E10

Like 10sec said, the ecu should compensate, however lowering your target open loop AFR a bit shouldn't hurt.
EDIT:I think that sbould be closed loop, those two always throw me for a loop
