Gave up on E85 tune but found a few somewhat local sheetz that have this?

No not the blue....you want the yellow "flexfuel" 51-83%....that's the liquid gold. I wouldn't even mess with that blue E15

Get a water based ethanol tester from summittracing and start testing that flexfuel pump to see what % it's delivering. Let your tuner know so he can go by that to setup your ethanol tune.

You still running a return-less setup? My current goals are just ported Eaton so If I can get away the $$ for a return system that would be great. From my limited knowledge there seems to be a lot of debate on this topic.

Proper returnless setup will handle around 700rwhp through a stick. You're only going to make around 500rwhp with a ported Eaton. Im at 508rwhp through an auto with 77% duty cycle on a returnless E85 setup. Difference between a returnless and return setup is only a couple hundred dollars. In your case you'd be fine with two Walbro 255lph E85 returnless pumps in your stock hat with stock lines, modified or dual fpdm, and larger injectors.

Not ideal. If you filled up with E55 vs E85 now you're screwed with a tank of shit gas.
I wouldn't call E55 shit gas as it's still way better than 93, but I get your point. In my case I have multiple ethanol tunes on my handheld. If my trims are showing off i simply switch to a tune that matches the blend, easy. I'm not going to pull into a station near empty, run a test in a vial, and decide to not fill up because it's only reading E70 or less. I'll just swap tunes and keep rocking.

That’s why you have a separate tune. It took KEVIN like 5 min to email me a 70 tune.

And like mentioned, E55 is light years better than 93. Plus you need way less than 85.

Gotcha, probably makes sense for how many miles I drive a day to consider a 93/E85 tune..although it will only be sunny days for 4/5 months a year it will be a pain for 50miles/day. How low do you have to run your tank in order to switch over a tune?

Just run it down to the fuel light you will be fine. Just be careful with the throttle the lower you go because you really don't want to beating on it with fuel that low. At least that's my opinion. Don't want the pumps exposed and overheating....and/or fuel starvation. Have at least 1/4 tank before going WOT again.

I'm not a fan of the factory hat and Y fitting.....in fact, I think it's junk and prone to failure the more you start leaning on it for volume....like in ethanol applications. My opinion....don't go ethanol until you have the budget to do the fuel system more "state of the art".

Yes, mine is returnless.....and works flawlessly going on ten years now....but the truth is, going full return is more cost effective these days and most tuners will prefer it. The parts are more readily available and less customization is necessary like with a one off returnless system. Go with Fore for the hat.

This might seem like overkill for your current eaton blower....but something tells me you won't stay with that blower for long and you'll have a whipple or TVS in its place before too long. Do the fuel system once, do it right....and you will thank me later on. This will save you money and headache in the long run. And your motor will have all the ethanol supply it needs to be in comfortable duty cycles for injectors and fuel pumps.

What he said. My last car I was playing catch up with my fuel system. I spent more than I needed to for a system that still wasn't enough. This time I went overboard. I may not ever need all of the capacity, but I like knowing there.

I was waiting for someone to mention the Gatorade bottle.
Wide mouth, less mess.
I’ve found on the street I really don’t test any more as my pumps are always 82-90. You’re fooling yourself if you think it matters in a small range like that; I’d even argue E70 on a normal E85 tune isn’t worth worrying on the street. So you run a little rich?
Now that I can get VP X85 for $35 a 5gal pale, I just run 5gal of the X85 with 1/4-1/2 tank of pump corn when I go to the track. Seems worth the protection.
I’d like to add an ethanol sensor next year just for fun.
The corn is worth it for the extra power, safety and cleaner burn.
Having great torque for the street full time is addicting.
I plan to drive up and run 9s this weekend on pump E85 and it’s crazy to be able to safely run 1000rwhp on sub $3 pump gas.

The reason I go ahead and test every time is I had a friend roll the dice, not test, and he got a tank of milky, junky E40ish out of an E85 pump we always go to. His vehicle started up, but threw a check engine light with multiple rich codes, and it ran like shiit. We limped it to his house, unhooked the line to the fuel filter and drained the tank. And this was a F150 HD tank to boot.....many many gallons.

I said from that point "Fxxx that....I'm testing". I only fill up maybe 6-8 times a year, so 4 minutes of extra time per stop is worth piece of mind.

there are also a couple of FB groups with local guys that give pretty frequent feedback on the local stations. We don't have to worry about winter blend here and seems the stations near me are always in the E80-E90 range.
