* empirically and optimized for the Victor 888. These values should work reasonably well for
* Victor 884 controllers as well but if users experience issues such as asymmetric behavior around
* the deadband or inability to saturate the controller in either direction, calibration is recommended.
* The calibration procedure can be found in the Victor 884 User Manual available from IFI.
