    Default Engine braking in DFCO

    Hey All, (1st post)
    Is there any way to control the throttle opening while in DFCO?
    I want less engine braking in DFCO. Throttle follower only seems to have an effect until DFCO cuts in.

    This is a great forum BTW, absolutely everything I needed was here to get me up and running with my LC-1 , Thanks so much,

    Cheers,
    Wayne

    Wayne,

    DFCO kills the fuel to the engine.

    No matter what throttle opening, timing is used NO fuel means NO fuel, and henceforce engine friction is what determines how much braking effect your combination will make.


    You can alter how quick DFCO comes in and make it feel seemless when coming in by the use of the injector cut sequence.
