@h4rp00n33r UPDATE: SUCCESS! Rudder AND Calibration!
I had the same problems as @WeamDreaver; controller not showing up in game, and axis being corrupted. It turns out, if you install vJoy, or make changes to “Configure vJoy” app, this bugs out the Xbox controller driver. The solution is to uninstall the xbox controller through Device manager (leave vJoy alone), and replug your controller 2-3 times till it shows up again in Devices and Printers.
Anytime you make any changes through vJoy, it will be necessary to reinstall the Xbox controller driver. Only after all this, proceed with UCR.
As for the calibration issue, I unmapped/cleared the aileron and elevator in MFS for the Xbox controller, and instead added another two axis through UCR for aileron and elevator. I then also calibrated the vJoy controller through Control Panel, and to my surprise MFS registered the calibration! No more drift that needs 15%, I can get away with 6% now! It turns out MFS ignores any calibration specific to the Xbox controller, but accepts them for other devices?
Remember, when trying to map the axis for vJoy in MFS, it won’t let you choose the axis when auto detecting the axis. It warns you that you can’t use an axis from another controller. Just don’t use the auto detection, and choose your axis from the drop down list for vJoy in MFS. It will be easier if you remove a bunch of unused vJoy axis from it’s own software, but remember you will bug out the Xbox controller drivers again, so reinstall them again through Device Manager.
@h4rp00n33r I can’t thank you enough for this, I’ve discovered something new with vJoy and UCR that I can apply to my other games too now! As for Lorby’s AxisAndOhs, this is another big wow! I haven’t tried it yet, but currently you can’t calibrate the right thumbstick through Control Panel, only left. The way I do it now is, I display the raw data during calibration through CP. I look at the minimum and maximum X and Y values, then find the middle value I need to recenter to. Then you have to simultaneously rest both the X and Y axis to the values you need to act as the center before pressing “next”, which is ridiculously hard as the ranges are from 0-64,000 for the Xbox controller. The slightest movement can throw you off by 500. So this Lorby’s software might come in handy for this, and also to calibrate the right thumbstick.
Thanks again!
