In my Mustang, DFCO only works after the coolant temperature has reached ~150°F. Then it will DFCO down to about 1500 RPM. With cruise control engaged, it will DFCO down to ~1000 RPM. Tapping the cruise control down is a great way to shed speed for a lower speed limit zone.
My (diesel) truck DFCO's anytime my foot is off the accelerator pedal and RPM is above idle RPM.
