Be sure you ALWAYS turn DCD function ON, or you don't save any gas.

Am I in error in understanding what this system proposal is and how it works?
Did someone comment on my comment and I missed it?
Alternate cylinder disabling via ignition and fuel cut-offs, in a rotating pattern (not the same cylinders being deactivated all the time), and without valve deactivation... did I just describe limp-home mode or hei's proposal?
I did both. Unless I missed it, this proposal functions the same as limp-home mode. Limp home mode saves NO fuel. Limp-home mode still has pumping losses. That seems to be a difficult concept for many to get.
