I run E85 through a cat. No issues so far. It's been over three years.

Do you need a flex fuel sensor if the Cobb AP can switch between two maps?

No. Thats not flex, you are talking about dual map setup.

E85 is perfectly safe with a catalytic converter. Tried and tested for over a decade.

It's definitely safe, I mean there are flex fuel cars running around from the factory that definitely have factory catalytic converters due to emissions laws.

I ran it most of last season with no issues, although I swapped in my "Higher Flow" unit for some racing events. ahem.

Leaded Race Gas will coat the inside of the cat and can ruin it in short order, definitely avoid that situation.
