Default Cobb FF vs "old style" dual map

I will try to make this make sense as I ask it.

I am currently running a traditional 93 tune and a E85 tune.

I have a VERY consistant gas station that I use for E85, and I nearly never run anything else but E85

That being said, would I gain/lose power on FF running the same fuel?

I know its tuned on a calibration scale (93 being low | Exx being the high)
Lets say your tuner says the E tune was E80... doe that mean if you have E85 in it, it will only make power up to E80, or can the tune adjust for higher than the calibrated "high" od the E80?

Long story short... is the FF worth the convenience factor for some one who ran 2 1/2 tanks of 93 in 18 months?

-Yes I searched... like crazy

Thanks folks!

The way i saw it in the program there is a maximum and minimum on the FF calibration page. You tune on 93 or e10 and you can vhoose the maximum amount which i would suggest be e90. To make the software more accurate try to run keep blending down the ethanol and type in the values you want for e90, then e85, then e75. It just makes it so that there isnt many hiccups involved when you mix and match ethanol content. It does however adjust on the fly and will only adjust to the max parameters the tuner has set in the map.

Is it worth it? Yes would be my answer. You never know unless you test every tank you fill. But with the FF you have piece of mind, versatility, convienience.

I too in love with E85 on my FF and Yes it well worth it. I don't have to worry if i ran out of E85 when i'm out of town. I live in the island. It become more and more E85 station around here.

Well while I understand the convenience factor, im just curious if it could be a handicap if its tuned on a lower grade of Ethanol than I run normally

If you can consistently get E85 then why would you have a tank of E80 when you go to your tuner?

Thats why i said that if you get the FF kit, when you get tuned to above what you usually run ex. E90 and set it and forget it.
