Aren't the burbles I'm hearing the fake OEM sound? Sure can't hear the burbles outside the car IMO, so was always assuming the burbles are the ASD fake sounds coming from the speakers. I'd assume the only way to get burbles would be if the OEM exhaust button changes some type of programming in the ECU (vs. just opening valves a little). I don't hear the same burbles with exhaust valves all the way open and OEM exhaust button off.

OEM mode, the exhaust button controls interior sound, exhaust valve open amount, and the exhaust burbles. It either turns them all on of off.

If you turn exhaust button OFF, you get no interior fake sound. NO pops and bangs and the exhaust valve is not open as much.

If you disabled ASD. That ONLY. REPEAT. ONLY removes the fake interior sound. (at least that's how I understand it)

So now that you have disabled ASD. Your exhaust button now only controls 2 of the 3 things. Now the exhaust button only controls if you hear burble pops and bangs and how open or closes your valve is.

NOW if you add a valve controller and override it to FULL OPEN. With ASD coded off. Now that exhaust button is ONLY controlling your burble pops and bangs.
