I understand that DCD isn't exactly the same as enriching to compensate for an oxygenated fuel but it's not so drastically different either.

Still seems like you're a). comparing apples to oranges, here; and b). you have no idea what you're talking about. To wit,

[sarcasm]Which is the perfect reason as to why vehicle manufacturers would not pursue a completely software-based cylinder deactivation scheme which would only cost the amount of software/firmware engineering needed to support it, in favor of multimillion dollar hardware design and re-tooling for hardware changes IN ADDITION TO the software/firmware changes that would go along with the new hardware so that it would support the "outmoded" yet somehow viable proven-to-work cylinder deactivation mechanisms that seem to be so popular with all of the major car manufacturers.[/sarcasm]

Or, supposing that you actually read those 7 pages you claimed to have read, you would have understood that it takes energy to pump air through an air pump, and that said energy is not expended when the intake and exhaust valves are left closed in deactivated cylinders. But I guess that thermodynamics and fluid dynamics are a bit beyond your comprehension.

If you're going to call that a conspiracy theory... well, rock on dood. I'm not here for "points"

I'm not drinking the hee-hee-tech kool-aid like you obviously did.

Spoken like somebody who has absolutely no clue about what goes on under the hood. Tell me, genius, how is a modern OBD II-compliant vehicle supposed to test its catalytic converter(s) with this hee-hee-tech garbage installed? You know, the one that is mandated? And tell me, brain, how would it be if the algorithm, that the engine controller uses that does the actual testing, fails out because it can't see the cycle-by-cycle variations in fuel delivery that it intentionally makes, because that flim-flam device is masking out said cycle-by-cycle variations?

Me? I have no product. I just managed to get better fuel savings than hee-hee-tech claims for his rip-off-o-matic gadget, using tried and tested "outmoded" principles.

Every so often, some snake-oil salesman comes along and tries to sell some sort of fraud gizmo here in an effort to try to get some veneer of respectability.

As to the rest of hee-hee-tech's claims, I say they're unequivocal bull turds. A device that supposedly saves at least 10% in fuel economy should be wildly popular right now. It should be flying off the shelves, so to speak, in this $4/gallon gasoline we're seeing. People should be clawing their way to the person who can actually demonstrate that such a device works for aftermarket retrofit. But, as with that other snake-oil device that had the CARB EO number, this DCD that hee-hee-tech puts out will be shown to be nothing but a fraud.

This thread really needs to go into the Unicorn Corral, now.
