"fuel management system"

[HCAbowman]

Whats happenin everyone, Ok, Ive gotta ask so forgive me if I seem dumb, but Ive heard lots of information on the radio about Dodge's new fuel management system, I guess to some of us that means "variable displacement" ie: Not runnin on all cylinders until its needed. Ive got to wonder if any of you out there know if there is a system like this for the V-10 or for any motor that Ford makes. I know back in the day that Honda, Chevy and some others have tried, just curious if there is something out there? in advance everyone!!
