    Flex Fuel map for Ford Fusion?

    Can someone share a (oem) map from a Flex Fuel Ford Fusion??

    Mine is a (base) 2014 Ford Fusion with the 2.0 Ecoboost motor and automatic transmission. And I am interested in modifying the base tune to run flex fuel.

    Thanks!

    None of the eco boost are flex fuel oem. I believe even e30 and e 85 tunes are not flex fuel but dedicated to that blend.

    I disagree. Flex fuel on 2020 Edge ST without any issue for 4ys and 30k+ miles. Done it other models as well with great results. It can be done if the tuner is smart enough to figure it out. My pump E85 here is E70-E75 typically and run that normally and will put 93 in if needed when out of town. I tell my wife to put anything in it, doesn't matter. It works on a sliding E content scale for parameters. Ford tuners arguing with me back in 2020 have no clue. I've not looked over a Fusion tune, but I'll venture to say it's doable considering what I know on other models.

    OP: you probably won't find a factory tune already set up for flex fuel.
