Lots of reading for you to do here:

so what i gather is about 4-5 gallons and thats it?

ballpark  on around 30% blend with 91 or 93 octane to be safe on 13+ models only .

can i run the 93 map with 91 mix

Are you tuned?

If so, by who?

If so, don't go screwing around without tuner support.

The tune has already put extra requirements on the fuel system and compounding it with E-85 wouldn't be wise.

If you're not tuned? Rephrase your question because I'm not sure what you are asking.

I'm guessing you are running a tune and you should probably address that question to your tuner .

tuner is coming livernois

Livernois does not recommend using E85.

 

[explorergotoluvit]

really ok i just dont get 93 here so feel like im going to miss out on the 93 4+ map

 

[DJE624]

You'll be fine on the 91 tune.  SOCALSHO uses it out in CA and his times were very close to mine when we were both running the Stage 4+. 

 

[SoCalSHO]

As much as I would like to run a 93 octane tune, as Dave says, my times are close to his. That's what happens when Californians are too cheap to want to buy the good stuff. Demand and then supply goes down.

I just checked.  My 1/8 time was 8.35 vs 8.38  Not even a third of a tenth apart.

k thanks

As others have mentioned, E85 is not something that should be played with. Just the inconsistency of the fuel alone is reason not to chance it. The problem is there are very few regulations on how E85 is blended and what it is blended with, so you can't trust it's octane level. Proponents of E85 will tell you to use a test strip to check ethanol content, but that's all it tells you, how much ethanol is in it, not what the rest of the stuff is.

WHEN E85 is good it's pretty cool stuff, but that's just the problem, you don't know when it's good or not. This is why, if you notice, there are no flex-fuel cars made that recommend premium fuel. Every Flex Fuel car and truck is designed to run on 87, or E85. Even the OEM's know that E85 cannot be trusted much beyond 87 octane.

We spent a great deal of time developing the calibrations we offer to ensure the most possible power while being reliable. I definitely feel your pain on only having 91, but we did our best to close the gap between the two tunes to those out west and south of us don't miss out on too much of the fun

It's consistent for myself and the tens of thousands of other users of it around the country making huge horsepower numbers  this fuel is awesome

While I think the consistency issue was true for many years, I think it's much better now. Find the MSDS sheet for whatever brand you are using and it will provide the needed data. MSDS data is not something you can play fast and loose with and expect to get away with it. The only consistency issue is when they switch blends for cold weather. I just found out it's a hard date, and not real time weather dependent. The car had no issue here, Ford's deductive fueling logic has worked flawlessly so far.

My question is why it can't work in conjunction with a tuned car?

Cause the cars fuel system isn't capable of suppling extra needed fuel. E85 requires a additional 30% of fuel and stock fuel system can't supply that extra amount of fuel:
