Well, kinda, yeah. Like the E85 kit I installed on my blazer a few years ago just intercepts the injector signal, extends its duration a bit, and lets the car's ECU make up the difference. Dead simple in theory, and whaddayaknow? It just plain works. 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.

My employer manufactures a lot of electronics, and our engineers come up with all sorts of neat features we could add to them. In the end, we don't really add most of the features our engineers come up with. Sometimes we leave a feature off a $1000 product because it would add four cents to the manufacturing cost. Sometimes we leave features off because we think they might increase warranty claims due to consumer incompetence, or because there are some circumstances where that feature pushes the product too close to a failure limit. Sometimes we leave features off because we run out of time to properly test and implement them in the final revision cycle. It's not a conspiracy to make worse products, it's just how product development goes.
My guess is, the engineers who have the luxury of designing a vehicle system like cylinder deactivation at the OEM stage can design a
complete system which includes the valve deactivation, and since they can, they do. If you're going to call that a conspiracy theory... well, rock on dood. I'm not here for "points"

Beats me, what makes you think this is impossible? The stock ECU's expecting a signal, you give it a signal, it's happy. People spoof devices and translate data all the time. I spoofed my jeep radio to think it still has a CD changer so I could hijack the cd changer input for mp3.. machines are just machines.

Business is rough like that, where's your product? I tried to open up a coffee shop when I was 18, and now it's not in business anymore - doesn't make me an a-hole.
What's your beef, anyway?
