    IMRC OP Threshold rpm

    On my 2016 F150 5.0 coyote, I see under Engine->Airflow->IMRC->Optimum Power->Threshold it has an RPM in there. Is the RPM present there the threshold that it must meet to enter OP mode or to change from Lo RPM Position to Hi RPM position or something entirely different?

    Stock file attached. Thanks.

    You have it correct. In OP mode this RPM is the point at which the RPMS above it and below it are Hi and Lo positions. as both hi and lo are set to open essentially the IMRC is always open when the truck is in OP mode.
