Ive been trying to hit ATTS since i got my 98 lude SH, and have been taking turns at 35-40. Ive still yet to see the ATTS light come on. How much does it take to engage ATTS. thx, i know the system works.

 

Heh, when the ATTS light comes on, that actually means that it is NOT working. The atts light functions much like the check engine light, in that if there is no light, there is no problems. As for telling when it engages, i once took an off-camber turn really fast and had one of the front wheels lift off the ground a little bit, the damn thing near pulled me off the side of the road because of the shift in torque distribution.
