Received mine yesterday. Put my car on the lift this morning and did the install. I did mount to the alternator cover also. Plug and pay. Took about 45 minutes all in with taking my time. Works perfectly and sounds great.

There seems to be only two modes (1 & 2) on the controller. How do we set the valves to OEM setting? Just deselect whichever mode (1 or 2) that you were on?

I think there are only two settings... "open" or "OEM control"

1= open, 2= stock functionality. There is a way to set the controller to “quiet start mode” instructions are online.

quiet start mode is exactly what I need to figure out.

I haven’t been able to find those instructions online.

I installed mine this evening but haven’t yet turned on the car to see that it works or hear the difference. Looking forward to that tomorrow!

Can't find the instructions to program quiet cold start either.

you're right... There are no instructions for setting quiet cold start online. There are only two buttons tho.. I would try long press button 1 first. If that doesn't work, long press both buttons. Or just email them to see how to do it.

Valve controller still on its way to me. Just emailed cargraphic about quiet cold start.

Reading the cargraphic description posted earlier and on their website though, it may turn out that this is something that has to be pre-arranged with cargraphic before ordering, since this feature is something to be offered as ‘vehicle-specific’..

hoping that’s not case since my real intention was to eliminate the loud cold start with the Akra exhaust (like brianja).

“Quiet engine start possible

For the Porsche 992 Carrera S / Carrera 4S with 3,0l Turbo engine, we offer a vehicle-specific valve control system that makes installation simple and easy, as well as allowing trackless refitting.
A special feature is the possibility of a "quiet" engine start: The programmable start mode allows the engine to be started either with the flaps open or closed, as desired.
The control unit either remembers the last mode used or you simply programme the desired flap position permanently.”

From Cargraphic re quiet start mode:

The start mode can be freely programmed as required.

Last state: Press the button for "Sport mode" 5 times within 5 seconds.
Other modes: Press the button for the mode you want to program as the start mode for about ten seconds.
The valves open and close 5 times to confirm the successful programming of the start mode.

Gotta say... you guys have been fantastic to deal with on all of this both in terms of ease of the group buy, follow up and knowledge sharing. Thanks!
