Nick Green Posted August 2, 2005 Share Posted August 2, 2005 Posting on behalf of ex-sevening/BC-ing friend: I Know there are quite a few Porsche-philes on BC, so can someone shed some light on this? I'm looking to buy a 986 Boxster S, and want PSM. It seems that earlier Ss had traction control as an option, and this was superseded by PSM around 2001. I know all about PSM from reading here, but can anyone tell me exactly what TC does? Does it just kill the power if it detects wheelspin, or maybe it could also brake the spinning wheel to transfer some torque to the other one thus mimicking an LSD? Also, does it monitor other stuff like yaw/slip angle etc? BTW, if anyone knows of a car, with PSM, for sale, ~25K please let me know.

Violet Elizabeth Posted August 2, 2005 Share Posted August 2, 2005 Yes MY01 986s had PSM instead of TC. TC just had 4 wheelspeed sensors. So would stop them spinning if if did. PSM added steering angle input, yaw and lateral sensors and brake sensor. It also can brake each wheel individually. And tries to keep you going in the direction you want to go, and the speed you want to go, whilst avoiding hedges ! It really is quite fun, as seems to well understand the difference between having a little hoon and trying to kill yourself.

rgrigsby Posted August 2, 2005 Share Posted August 2, 2005 The boxter S I drove had PSM and it was superb, barely noticeable with it on, suprising how slidey the car was with it off! Rob G www.SpeedySeven.com Link to comment Share on other sites More sharing options...
Peter T Posted August 2, 2005 Share Posted August 2, 2005 Porsche PSM only brakes each wheel if it detects wheelspin. In extreme cases it will reduce engine throttle inputs. PSM costs about £1800 as an extra, so quite a lot of boxsters do not have it, as their measly power outputs and costs do not justify. 😬 Carbon Components from K9 Composites Link to comment Share on other sites More sharing options...
Violet Elizabeth Posted August 2, 2005 Share Posted August 2, 2005 PSM is now standard on the 2005 Boxster S. But you are right, putting the engine somewhere sensible, rather than somewhere no sane person would put it, means you don't really need it on a Boxster The (slow) birth of the Gixxerham : Pics here now with extra drivel here Link to comment Share on other sites More sharing options...
