You can damage the engine running the valves closed at high RPM and overriding the OEM valve control.

See above... I'm not sure this is correct. When the Cargraphic controller is in "Open" mode, the valves stay open all of the time. On a non-GT3 car, the "closed" option is really OEM control. So the exhaust control button (sport/normal) works as per normal from the factory. There is no "permanent" closed valve option.

I think of it this way... "open" is loud all of the time. "Closed" is stock functionality with the car controlling the valves just like it did the first day you picked it up from the dealer

Looks like several companies sell this valve controller under different names - Cargraphic, Kies, Capristo, and ASR. Perhaps some others.
Does anyone know who designed the controller and has licensed it out to other companies?
The ASR Germany website has a nice video showing how the exhaust valves are working with the control module and how open and close the exhaust works with or without the module working on a 992 Targa 4GTS. Some video inside and outside the car.
YouTube can translate the German to English.
I'll try and link the video. It's about 15 minutes.

Anyone install one of these lately? Seems like a really simple and great exhaust mod, but I see many posts about error codes, reduced power warnings and interment failures. Looking to see how these are holding up. Would like the extra sound but don’t want error codes, headaches or drone.

I love my valve controller now. My recommendation is to buy it with confidence from any vendor who will give you assurance that they will stand behind the product if there is a problem, including replacing it. If you get a faulty one (a small percentage I would think) you will know it quickly.
As for droning, one man's drone is another man's music. I used to work in Automotive NVH testing and I will tell you that there is some drone (as it is technically defined) at certain speeds and loads with the valves open. If it annoys you just close the valves. As for myself, I keep the valves open all the time. Music!

I'm still really happy with my controller, but recently I seem to have lost the ability to have the valves default to OEM operation at startup. They always start in the open position, leading to a VERY loud cold start with my Akrapovic exhaust. My neighbors must hate me. The controller works correctly otherwise... changing modes without an issue.
I've tried the "press the mode that you want it to start in 5 times quickly" method to program the module, but it isn't taking.
Any insight from the group?
Thanks.
