    Re: PASM suspension problem - Update

    SD987, still, wouldn't you think there's an obvious problem if PASM only works properly in a higher rev range or it least feels stable whereas at "babying rev" as you say it seems unsettled? One has to believe that PASM is mean to work at all engine speeds and be equally adaptive and stable throughout the range. With what you're suggesting, PASM is only meant to be stable and safe when driving hard, cornering, accelerating and braking... how functional is that?

    Re: PASM suspension problem

    Continuing observations...

    Car hasn't descended into the 'uncontrolled' rock had but yet wallowy and unresponsive feel that it had before the PASM control unit was swapped.

    However, sometimes it seems to wander from the 'perfect'. Sometimes the steering gets a little vague and less sharp, and at the same time it can start crashing over manhole covers - and this when just gently cruising round town.

    Other times it can be that beautiful ride quality, ironing out all the road imperfections, retaining traction mid bend, steering sharp and direct as a knife, minimal body roll.

    I used to hate throwing the car round corners, as any road imperfections would cause shudders through the cabin and the car would want to step across the white line.

    Now it's much better, but still sometimes you feel less than confident.

    Just one thing though... I think the PSM has died. There have been a couple of times recently, pulling away on a wet road, where I would have expected the traction control to kick in. Will test this properly when I'm not in traffic. (I noticed this just before the PASM unit was swapped, so should be unrelated)

    Re: PASM suspension problem

    Some time passes...

    Seems to be getting flakey again gradually... still not as bad as it was, but getting less controlled I think. Sigh.

    Re: PASM suspension problem

    i see from a recent copy of 911 +Porsche World magazine that Richard (TVMan) has bought another Cayman

    Re: PASM suspension problem

    Has he taken delivery then? I knew he had part-exed against a new one. Hope that one is better!

    Richard? What's the verdict?
