Did you add a flex fuel sensor into fuel system? Your car is not equipped from factory for E85.
2023 Ford Edge ST
2020 Ford F150 King Ranch 5.0
they use the factory widebands to infer ethanol content, we can basically use it as the flex fuel f150 coyote trucks operate that way stock
You need to study flex tunes a bit more. Start by copying over all the fuel tables from a F150.
You have several tables that need to be filled in. It's not just enabling the flex, Ford did not fill in the fuel tables.
Don't drive it.
I might have time tonight to fix your tune.
i did use a f150 tune to populate tables that where blank, but i dont see anything i left, thank you for your helpOriginally Posted by K44
Similar issue and no help to you but I can’t seem to make gen3 (Whipple strategy) octane learn work.
There is a setting in forscan to enable flex fuel. Could that be your issue? I know the pcm references offer modules for data in some cases.
give this a try now
Sorry, I took a quick look and thought I saw some tables with nothing.
That will teach me to look without my readers on. Outside of changing the min stoich as Boosty did, I got nothing.
just an update, the car seems to be inconsistent in learning, sometimes will learn, others will just give me a "system too lean" code
just a thought can you run this straight e85 & make sure its all ok the try it back on to flex ?
E85 is not available at the pumps here, so im using 5gal jugs from vp racing, this car might never se true E85 as im using this as a "race fuel tune" for track nights
can you do another log something else is going on here may not be tune related ?
I wonder if this has anything to do with your problem

I have 2 separate ethanol tunes, one is for competition where I run E85 (VP X85) and use auxiliary injectors and an auxiliary controller. The other is for pump flex fuel and street use. The flex fuel tune does not produce any additional horsepower itself, the extra power is dependant on the quality of the fuel, which is unpredictable. However, it does make my motor less prone to knock, and is more affordable than 91/93 octane pump gas.
