And how again do you propose to eliminate excessive NOx and unburnt hydrocarbon emissions with this DCD gadget?
Unless you pass one of them mobile emissions checking trailers. Or until your cat burns out from excess unburnt fuel. Or until your engine starts burning oil from worn-out piston rings due to fuel-diluted oil.

I think you're missing the point of the system. The "dead" cylinders' fuel injectors won't fire, there won't be unburnt fuel. Spraying fuel into the "dead" cylinders would defeat the purpose of the product. And from what I'm reading, it's tricks the ECU into fueling the working cylinders as normal, keeping afrs straight.
Just my 2 cents with out reading his entire article (Let me know if I've missed something, and fuel injectors still spray into cylinders with no spark), and based on what he's posted here.
