Wouldn't it run too lean? If the DME is targeting 14.7 AFR that would be too lean for mostly E85 right?

Might be okay to drive around lightly, avoid WOT. You could also siphon out fuel into 5 gallon jugs.

No worries, just don't go more than like %50 throttle.

Once the tank goes down to like half a tank, fill the rest 91 and you should be good.

To further calm your concerns and not knowing where you are geographically, the ethanol content at the pump could be as low as E70 this time of year.

In colder climates where temps can drop down to single digit or lower, the E85 pumps change to a winter grade with as low as E70 to address known cold starting issues with high concentrations of ethanol in flex fuel vehicles.

Unfortunately, the pump labeling does not change to reflect the level of ethanol concentration as it changes throughout the season, but it does specify “Minimum 70% Ethanol Content”. You can google the topic for more info.
