My 97 M3/4 has ASC on it and I was wondering if anyone had any info on how this system worked and it's pros and cons. What is the difference between ASC and ASC+T. I'm assuming mine just has ASC since that is all it says when I push the button. When the light comes on the dash, the ASC is off (correct?), but I really can't tell that much difference. Any info and advice would be appreciated. I'm trying to learn all the stuff on this new car.
