    3.5L Ecoboost Timing adjust by FFV content

    I see in the flex fuel part of the cal there's a blend curve for ignition timing by ethanol content (11527), I'm curious where the map for this multiplier lives?

    I'd like to adjust the timing by ethanol content. It's not slapping me in the face. Any help would be appreciated.

    Also, does anyone have a file for a 3.5 Ecoboost Ford GT? Just curious to see how the factory handles things at that power level.


    Thanks!

    Any update on this? the gen 2 3.5L ecoboost definitions seems to be missing the "spark"->"advance"->"fuel"->"FFV multiplier" and "FFV modifier" tables (21330 and 44584)

    from the research I've done lately it seems like it was intentionally left out of the ecoboost strategy (because it's not an FFV from the factory), so unless HPT adds/revises code it's essentially not going to happen
