I suspect the Electrical motor is spinning the engine in DFCO... with a OBD reader you can see 0.00v on the upstream o2 sensor. that mean no fuel to air ratio.
when i first saw that i thought my sensor was broken or some other issue..
since there is no "engine braking"
it feels like it's in "neutral gear"
if I shift it into Manual Mode it has "engine braking" and you stop pretty quickly

Are you saying aggressive as in, it barely slows down? I would interpret aggressive as sudden and strong braking action.
The scangauge says my Accord is open loop when DFCO'ing. I don't have the capabilities for monitoring sensor voltage. DFCO in general means cutting fuel while slowing down. The electric motor doesn't have to help spin the engine, as the momentum of the vehicle is already doing that. It may be true that the motor is helping spin the engine under DFCO, but it is also likely that manual mode causes regen, resulting in that increased braking feel.

That's good, cause i've got some worn ecopias and am about ready to swap to the energy savers.
