It sounds like what you want to do is change the default programming to position the PWM output to a different set of pins. You can only do this in software.
Calibrating the speed controllers allows you to utilize the full range of motor control based on your joysticks. When you hold the calibrate button in and move the joysticks to the full extent (full forward, full reverse, full forward, full reverse, and then let the joystick return to rest before releasing the calibrate button) you have now instructed the controller to modify it's decoding to recognize what you send will now be full range. After calibration, full forward on the joystick will give you a full 12 volts at the motor, a full back on the joystick will give you reverse 12 volts at the motor and when you let go the speed controller will send no voltage to the motor.
