    1999 Carrera C2 Cabriolet
  1. TC is more primitive than PSM. TC does two things: 1. The ASR function detects both rear wheels spinning and cuts the throttle. 2. The ABD function detects one rear wheel spinning and applies the brake on that wheel to allow more torque to to be applied to the wheel with better traction. ABD only functions below 60 MPH. However, it remains active when you hit the switch to turn off TC. (This is helpful on the track.) PSM performs the same functions as well as detecting understeer and oversteer and attempting to correct by pulsing the brake on individual wheels. My car has TC and I can tell you from experience that it does not prevent the rear end from coming around. Once I applied a bit too much throttle while exiting a turn on a wet road and I experienced a major tank slapper as I worked to regain control. Thanks!!! I hoping not to find out the hard way. I've heard that many Porsche owners see a wall/barrier in their rearview mirror just before some major body work. Best Regards.
  2. Does anyone know if traction control on a 1999 C2 works at all speeds? For instance, if you mash the throttle at the apex of a sharp corner, will TC prevent the tail end from breaking loose? How does TC compare to the PSM system?
