    BCM has nothing to do with the engine at all. its the body control module, its the brain for the inside of the cab. PCM is what controls the engine and tranny. power control module.

    Thermostats—- 160* vs 187*

    normal operating temp is 210, so the t stat should not be the issue. try the right fuel filter who knows it might be restricting the fuel and running lean and causing the misfires.

    Serious Hard Starting Issues Continue...HELP!

    https://cartreatments.com/p0178/ likely need a new flex fuel sensor. if the engine cant tell what fuel, or the e85 content, long crank/ start can happen. if your running e85 right now, for sure, as its got no idea what fuel is being used.

    Manual switch for efans?

    i'd think you'd just have to get power to the relay for the fans to make em kick on. or add a external trans cooler. can even put a inline t stat and a fan on them.
