Re: Victor 884 calibration

As a rule of thumb, you always want to start by calibrating your joystick such that it outputs 127 when it is centered.
I could not agree with this more. Keep neutral 127. The Chicklets are production calibrated with this in mind. This means that when the device(gamepad/joystick) is unplugged from the Chicklet, the Chicklet will set its outputs to 127. This is only valid if your device returns to center. The purpose of the user calibration is to correct for inaccuracies in the device(gamepad/joystick). User calibration should be performed with any new device and that device should be matched and used with the chicklet that it was calibrated with.
