Hello! I have JB4 I got it about a month ago brand new and I have it installed. When I click the sport button sometimes I do not hear the exhaust open (the click noise). I read on another thread about the BC button and that worked, But I do NOT want to use Jb4 to open and close my exhaust. I want to use the sport button to open and close it. Is there a way to not let jb4 touch my exhaust flap and exclusively control it with the sport button?

i have the same problem also
you can just set it to be open all the time
like i did for now, i hope until the guys at BMS will fix it in the next update

Try changing the JB4 canflap setting by adding "canflap" as a gauge in the app and double-clicking it, to see what happens.

Also using your left turn signal stalk, holding the BC button while in park will toggle the canflap. You will see on your dash it's toggling by it flashing your turn signals

Hold BC for 3-4 seconds

Left arrow blink open
Right arrow blink closed
Both arrows is stock
