It goes against what I thought DFCO was all about. Have you watched instant fuel economy while coasting? Maybe I'm missing something.
You have to be in gear for DCFO to work. It keeps the engine running by the energy of the car rolling. If you shift into neutral, you're disengaging the engine from that free energy and the car then has to find some other energy to keep the engine turning, so it switches to idle and kicks the injectors back on. if you want movement with no fuel you either have to leave it in gear while coasting or turn the key to shut the engine off completely.
