Personally, I could never give up the flexibility of valves. For those that don't want to lose that function, keep a wireless OBD adapter always plugged in and use the Bimmerlink app. I use a Veepeak bluetooth adapter since my phone connects through wifi to carplay; wouldn't be able to connect to carplay and a WiFi adapter like THOR at the same time.
I'd say for the majority of the time I leave the valves in auto so it's open in the first few gears but unless you're on it it'll close back up when cruising at higher speeds. But if I ever want full valve open action I just open the app and toggle the valves for more sound!
