    I ran E85 in my Suburban . With 85 to 87 octane I get around 16.3 MPG. With E85 I was getting 10.2MPG. Not worth it in my opinion.

    My wife thinks I only have 3 guns

    I've had the factory flex fuel logic running on my '18 for ~4 months/4500 miles and roughly 10 fill-ups of varying ethanol content between E10 and E55. I've yet to see a matured ethanol content >4% off from measured via an external continental sensor. Generally takes a single 10 minute highway & city drive to get the ethanol content to mature.

    I think there's nothing wrong with utilizing the factory Ford logic, especially considering how many million cars/trucks currently running just fine with it. Even though we're "pushing" the limits with increased output, it should be able to be calibrated correctly with adequate safety margin and significantly improved ease of implementation. The problem will be modifying the Ecoboost strategy to use the "full" Ford flex logic that's in the production flex fuel strategies.

    Any developments with the Accessport being able to show the inferred ethanol percentage PID?
