For E90 A/S its 1.5 turns lock to lock on low speed, and on the highway its 3 turns lock to lock.  I believe the normal and M sport E90 steering ratio is 2.92 (I think the E9x M3's ratio is 2.5 turns lock to lock).  So on the highway, the A/S equipped car is a little more lazy and relaxed compared to the standard non A/S ratio and the M3.Not too sure about the the exact way A/S works with the DSC as well tho.  Definitely some integration, and my guess is that it varies the ratio according to your countermeasure input.  I.e. if the DSC senses an opposite lock is required, then as you turn your steering angle to induce it, the steering angle sensor detects what you are trying to do and DSC shortens the steering ratio so that you achieve it faster?? Thats just my guess tho heh.</blockquote>
