Interesting. I have a button called PDCC. When I press it the dash says "PDCC" on. Unlike my 997.2 there is no button for sport suspension. I guess that means normal PDCC vs sport PDCC.

 

I conveniently have this same button. It can be turned on and off. There may be a constant component of pdcc that we can't see but there is definitely also an on and off button. And there is definitely a feeling difference when it's on vs when it's off.

 

You're just putting it in the sport mode. The PDCC is always working, which is why a PDCC equipped car rides much better on bumpy roads than the standard suspension.

 

Ahhhh. Thanks for the clarification. That makes sense. It rides great on the bumps until I push the button and then you feel them much more - ie the sport setting I guess.

 

All good information. I suspect the improved tire life would occur on both modes. All excellent technical info that the OP would want but going back to his original post. The car is flatter on turn in but the non-PDCC suspension is also excellent. It's an expensive option so I can't honestly say it was worth the money. I just like the tech although if it breaks...........There has already been 1 update to the software.

 

Humm.

My center console 13 C4S with PDCC w/ PASM sport suspension

 

If you get PDCC the other suspension buttons are gone and just one that says PDCC. At least for 2014.

 

And 2015.

 

i did a search and saw a Euro Turbo has the PASM (shock absorber icon) and PDCC listed on the same button. I don't think the U.S. cars show it that way, or at least I haven't seen it. No matter, PDCC is always "on"...I guess they just want to show that it adjusts based on the suspension setting.

Anyway, down the road it will be a useful clue when determining the model year of a car.

 

In searching I found on another forum talking about a button change from MY 13 to 14.

 

That is correct. There is a change in button between MY13 and MY14.

MY13 has a PASM button. Pushing it turns on Chassis Sport. No separate button for PDCC. PDCC always on.
MY14 has button that says PDCC. Is there no separate button for PASM? If not then how do you change the setting for PASM?

 

I'm updating this post with the help of LexVan's and others' posts below.

I've spent quite a bit of time trying to understand PASM, PASM Sport, Sport Chrono, and PDCC. I think that I've got it and I think that this post re-confirms my understanding, but could I try a recap for my own benefit (and maybe for others)? Please comment/correct as necessary.

Sport Button and PASM do three things - they control the dampers, throttle response and PDK shift mapping. PASM adds the "shock absorber" or Damper button to the center console. If you have PASM and press the Sport button, the Damper button also lights, the dampers firm, and the throttle response and PDK shift mapping become more aggressive. You can press the Damper button to return the dampers to Normal mode, but maintain the Sport button's throttle response and PDK shift mapping. PSE (if you have it) also turns on when you press the Sport button and can be independently turned off.

PASM Sport lowers the car by 10mm and firms the ride further when in Sport mode (and the Damper button is lit).

The Sport Chrono package adds the Sport Plus button. The Sport Plus button works just like the Sport button. It further impacts the firmness of the dampers as well as providing even more aggressive throttle response. I don't think it has any impact on the PDK shift mapping (but adds Launch Control and a bunch of other stuff).

PDCC is a roll stabilization system. Although some feel that it provides a more compliant ride, I believe that it really only flattens the car going through curves. On some cars (model year dependent?) PDCC adds the letters "PDCC" to the Damper button. But that button is not turning PDCC on or off. As others have said, PDCC is always active and has three levels of aggressiveness - Normal, Sport and Sport Plus - depending on which buttons you have available and lit.

What do I have wrong??

 

So I played with PDCC on the way home today. When you press the "PDCC" button it say "sport chassis on". When you turn if off it says "normal chassis". So the above posters were all correct. Same button. Just says PDCC instead of sport pasm. Just a way to acknowledge the car is equipped with PDCC. So to repeat above posts. PDCC is always on. Press PDCC button if you want sport chassis. If you press "sport plus" the sport chassis is automatically engaged as well. I learned something today so thank-you to above posters. I will now leave my car in the normal mode for daily driving. I love it when a plan comes together! Thanks again.

EDIT:Sport pasm lowers car by 10mm more than pasm all the time.(not engaged by any button)
:On my 2014, only sport plus engages the sport chasis. Sport does not. In sport you must press the PDCC button separately.

 

PASM is Porsche Active Suspension Management. It has nothing to do with engine mapping and throttle response.

Sport Chrono controls throttle response and the engagement parameters of PSM (Porsche Stability Management).

These are a couple of the main corrections necessary.

 

OK...now how does DEM (dynamic engine mounts?) work in this scenario? Seems like there is some redundancy here..NO?
