Cool… imma gonna have to look into this more, its a subject that i am now very intrested in, thanks!

and for the “displacement on demand” or cars that shut off cylinders, they do this in sequence to the vehicles timing, hence, cylinder 1 spark shut off, the injector is also nill… remember the old caddy 4-6-8… what a joke, this engine did not shut off timing, and we all knows what happened to those motors =)

great topic, i like this kind of conversation, it also helps out in my job, gets you thinking more… :tup:
