TCA Boeing Quadrant throttle calibration issue in FSUIPC (MSFS 2020)

Hi everyone,

I'm reconfiguring the throttle controls for my Thrustmaster TCA Boeing Quadrant using FSUIPC, and I'm running into an issue. As soon as I move the lever just a little bit, the throttle quickly jumps straight to the maximum, and it won't let me bring it back down when I pull the lever back to reduce power.

To avoid conflicts, I have completely removed all throttle assignments inside MSFS 2020 because I want to manage all my controls exclusively through FSUIPC. However, I'm not sure if this is why the power increase isn't matching my physical lever movement.

I'm stuck and don't know what the cause could be. Could anyone help me properly configure my throttle quadrant in FSUIPC so that it accurately follows my lever movements?

Thanks in advance!

This can be caused by your device' axis being registered (in the windows registry) as a digital on/off axis. To correct for this, you need to unplug your device, remove the registry entries, reboot and then re-connect your device. See the following post for more detailed instructions:

If you still have issues after doing that, please show me / attach your FSUIPC7.ini and FSUIPC7.log files.

Thank you very much for the quick response. I will proceed as you indicated, and if it doesn't work, I will show / attach you the two files you mentioned.
