If you have techsteam and under body and chasis. Go to customize and other change body control chasis torque to off. It disables the pitch and bounce feature and this made my prius v (lowercase v for the Prius v wagon. Only 2010 Prius used uppercase roman numerals for model designation) feel so much more responsive in normal mode. They say to disable this feature if you change any suspension parts with aftermarket. Please check it out. I dont notice a difference in ride quality but I do notice a difference with throttle response.
Since "Pitch and Bounce Control for the Prius v" works only on low frequency longitudinal oscillations, changing spring rates would change the pitch oscillation frequency and thus the system's behavior, but adding ARBs or chassis stiffeners which operate in the roll axis would not. Since the system functions by modulating motor torque, disabling it would eliminate the low frequency +/- modulation of motor torque
I think Nissan's Active Ride control works the same way and their explanation is definitely clearer to me. Can't find much details on Toyota's.
