    PASM Question for the Technically Inclined

    The Porshe website includes the following about PASM:

    "If "Normal" mode is selected, and the car is driven assertively, PASM automatically switches to a harder rating within the "Normal" setup band. As the dampers become stiffer, the car becomes more stable and responds more quickly to driver inputs."

    After 7,000 miles it seems that my 997S in Normal mode is much stiffer than even a 1,000 miles ago. I am a very aggresive driver so I wonder if all of the cumulative "assertive" miles I've put on the car have made my suspension generally stiffer. In fact, it seems that the difference between Sport and Normal mode has diminsihed significantly. Any thoughts or similar experiences out there?

    Re: PASM Question for the Technically Inclined

    i'd be shocked if the "learning memory" was based on more than just a few seconds worth of data

    Re: PASM Question for the Technically Inclined

    Are you tires worn down a lot? This could give you a harsher ride.

    Re: PASM Question for the Technically Inclined

    It sounds like your sport setting is "stuck" on mate! Mine is quite different between the two modes.

    Re: PASM Question for the Technically Inclined

    Do you have the tire pressure monitoring system on your car? I notice that my ride is getting harder, within the normal setting, as the air temperatures have gotten higher, and of course, the tire pressure readings have gone up 1-2 lbs. As I worry about damaging the wheels by running with lower pressures (at least when starting out on a drive), I just put up with it, even though I generally am not super aggressive when driving.

    Conversely, I have the feeling that mine gets stuck at the soft end of soft. I'm a pretty aggressive driver, but a lot of my route home is cuising at 80-90mph. Currently in process of querying this with the dealership. Will post the outcome when I know. V.V.annoying.

    Re: PASM Question for the Technically Inclined

    its just your impression, but not real. its weard cause the normal thing would be to find it softer as you get used to it and drive harder. only my opinion, but i feel the sport mode much more normal than when i bought it tahat felt really hard. now i think i should had boght the slip dif option.

    Re: PASM Question for the Technically Inclined

    Don't get me wrong guys, it's actually sort of a blessing as I used to feel like the normal mode was too soft most of the time. But I appreciated the soft ride on the freeway home from work after a long day. Now that is gone and it's just a hard ride all the time.

    There's definitely something wrong - You should get a choice!!

    No, it still works -- there is still a choice and I can tell the difference between the two modes. It just seems that the Normal mode is harder than before.

    I take it you have checked your tyre pressures?
