I've seen some old threads that say it doesn't work. I see they are still advertised, so I'd have to guess that they do. I've installed plenty of them on previous generations but I haven't seen one on a C8. What's consensus on this?

I have not seen a post that says it worked. But - if it did - what is is supposed to do that you can't already do by setting the exhaust sound in Z mode?
I have read (on the forum) that valves have only two positions - open or closed - and the settings just adjust the conditions under which the valves open. I attached the relevant section from the Shop Manual, below that seem to list those cases. The manual also says that the valves actuators are commanded by pulse width modulation of the control signal (that is attached too). I am curious about that, since I thought that type of control signal was used to control something that was not just open-closed, or on-off, but rather had different positions or speeds in between - which would not be consistent with the idea that the valves have only two positions. In the shop manual you can see that the car makes extensive use of PWM signals to control things like fan speed, etc.

I've read varying opinions on this. Some say that the valves partially close for sound compliance (or some such nonsense) and some say they are open all the way. It sure sounds like it's al least partially closed at low speeds, even when programmed to track mode.
I guess I'll roll it on my dyno, with the camera stuck up the pipe and see what I see under different conditions.
If it is open all the way, I'll look at modifying the internals of the muffler, much like we used to do on the C6 Z06.
So... Does the Mild2 Wild work?
