I think a product like this should work - not as well as an OEM solution that addresses the valve opening/closing, but still it should work quite well. Perhaps I misread something but I don't see how this would put the engine in open loop mode, if the engine's ECU believes it fired the injector, and the DCD box takes input from the wideband o2 sensor, compares it against the number of deactivations it knows it made, and produces a voltage the ECU was expecting from its ordinary o2 sensor... then what's the problem? Sounds like a closed feedback loop to me.

I hope this product gets made, and I may just buy one if/when it's available for my car.
5% to 15% Fuel Savings Could be Yield from DCD ----- This result is from
DCD-440 product running on 1.6L 4-cylinder vehicle with AT. The result is
based on professional comparative fuel consumption meter test. Real world
MPG could have a gain of 20% to 24%, but this includes the drive habit
change forced by DCD's power reduction, keep cruising under cruise control.

Trying is believing. For those who don't believe DCD, the fact is here waving
to you. I have saved some gas by DCD, while others who don't have DCD
may not.
