I suspect that since you opened two instances of the drive system, they were competing with each other.

I'm enclosing a VI that shows how we opened our Joystick and the Archade Drive System using 4 motors. The code only identifies a 2 motor drive system, the "Y" cable from PWM1 goes to both motor controllers on the left side and the "Y" cable from PWM2 goes to both motor controllers on the right side. All motor control's MUST be of the same type; ie: Talon, Victor, Jaguar.
