Why "Forget about O2 sensor feedback"? I told many times that DCD's fuel
saving secrute is by WBO2 Sensor, which determines the target of high-
lambda control. You may know what is high lambda? It should be much higher
than the unity. Then you may figure out how much fuel would be injected vs
air intaken? You was wrong to expect more fuel injected.
Misfiring? That's a trouble to most conventional engines that needs to be
avoid. But to DCD controlled engines, "misfiring" is what we wanted, it's
the sign of DCD in progress, but don't have real physical misfiring. If you
are afried to see "check engine" light on, I can put it off by program.
limp-in mode? DCD has been tested on real vehicles for over 2-years, and
had, has never "limp-in mode" happened, because no vehicle is designed
so stupid. "check engine" light on and OBD-II codes are enough to present
the trouble. Why make more trouble by limp-in mode? In fact, for many
times I demo my DCD controlled vehicle to passangers, they even don't
know DCD CONTROLL has been changed from off to on to max in multiple
stages, engine still runs smooth under DCD control.
