I wonder why BMW didn't offer the non-EDC ZCP set up in the US like the one that was offered in Japan, that would have given them more of a margin, unless the ZCP EDC is really that much better for the car.
There is a small article on BMW Mpower website re the ZCP / Competition EDC settings. I recall that standard EDC modes are fixed whereas for the Competition they are dynamic like in the Jaguar XFR model. I would assume therefore, that the difference would be noticeable on bumpy roads.
