I just stumbled on this thread and got to about page 7 before getting bored of the negativity being thrown at this guy.

We're his intended market, and he's trying to make something commercially viable and he was all but attacked over it.

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.
