Opening exhaust valves with JB4

Hey guys, I'm currently running a jb4 with posi tap connections, but I can't figure out for the life of me how to change stuff like keeping exhaust valves open all the time. I can change maps with the volume button (although there is no actual indication that the map has changed other than through my laptop). Does anyone know how to do it? Or am I behind on my firmware or something?

Is that only for the individual can flap module? or is that a built in function?

If using positap firmware 3.31 then use the press and hold voice command button on SW for about 3 secs to open can flap. Repeat to set back to standard can flap setting

He has posi tap connections, you have the newest version with OBD

Different firmware, different control buttons

Update: I had to update my firmware to get it to work. The voice control button worked for me (posi tap version)
