So you never know what you really have

That is correct, the only way to know is to use an analyzer. To me that seems a pretty wide range but apparently Wisconsin gives them a wide range of ethanol content while still allowing it to be labeled as e85. I use the same station all of the time for both my 93 octane and my e85 with the same ratio 50/50 hoping I get at least some consistency. My car has run excellent since i have been doing this so I'm not complaining. Eventually I will get the ethanol analyzer, not in my budget at the moment.

E85 Specification
ASTM International developed a specification for gasoline-ethanol blends containing 51%-83% ethanol to ensure proper vehicle starting, operation, and safety in varying temperature conditions

It gets cold here in the winter so lower ethanol content is used then, that sucks

Did a few test runs today after flashing the BEF back to my stock flash and trying out map 5. This is about the 6th pull, any suggestions?

Did we ever figure out the issue with trims getting stuck at 25? I'm seeing that in some of my logs and I'm pretty sure it's causing some issues.
