Can I set up S mode to keep the suspension in soft? My car will have DDC.

 

You can tell sport mode to only make the engine changes and not the suspension changes, but I think you'll end up in the middle setting vs the softest setting. Not sure if you can tweak it further with Bimmercode.

 

Is the way you do that through the "Configure Sport" option that shows up when I switch from (default) "middle" to Sport? And if I do that, is the way to get back to the "sport" suspension setting to go through the same option?

 

Yep, exactly.
