ok maybe i am way off here but even though the ATTS lets both wheels spin its nothing like a lsd. The lsd makes both wheels spin at the same time where the atts put more power to the wheel to help the car grip. Its a steering system. My bud has a lsd in his rsx and i have seen it slid when he is hard in it in curves because the wheels are spinning at the same rate and they slide instead of grip. ATTS for the curves and LSD for the launches.
