sorry I should have clarified I hace a 2000 S which doesn't have PASM. 
 
I'd like to see if there is a comprehensive analysis of the Porsche ABS system.
And tips for preventing its need.  I was always told that with ABS you wanted to pump the brakes which is completely the opposite of what I have trained myslef to do. For instance in autocross I'm often  "quick hard and quick off" the brakes before making a fast turn.  It was a trick to do this without locking up the brakes with my old Miata. With ABS its going to be another challenge.
