    E85

    For E85 on Hellcats, are you guys using the alcohol tables, or using same values in alcohol /non - alcohol tables?

    Should be an option when you select OS details.

    Are you running it on E85 all the time or are you wanting to add the flex fuel option?

    E85 only, want to get a bit aggressive with the tune.

    Off topic, but man, I do not approve of the OP’s screen name. Folks seem to be confusing you with me for what’s probably not obvious reasons.

    Anyways, applying the flex fuel patch does not automatically make the tune flex fuel out of the box. It still requires a bit of work and adjustment to get it tuned properly to infer ethanol % and blend across the different 93 vs ethanol tables. I haven’t tried the patch on a 2018+ yet myself but it does work on 2015-2017 Hellcats if you can figure it out.
