2021 F150 3.5L EcoBoost Ethanol Content % PID

[Tuffram1996]

Can someone point me in the direction to enable the ethanol content % PID with FORScan? PID Address and what value to change?

There's no ethanol content PID for these Gen3 3.5's that I know of, but there is an OAR PID, which can at least let you know you are getting good anti-knock.

Hopefully I'm wrong and a PID guru shows up and we can pick his brain.

I have the OAR and KS ones already. I have read where it has it because the 5.0L 21+ trucks are flex fuel again. The PID is in the 3.5L EcoBoost ECM'S and it will function same as in a 5.0 truck but just needs to be enabled.
