Pete,
I have updated the latest FSUIPC 5.103 and PFCHID 1.49 / PFChid64 and found everything worked great except the throttle body for my TPM ( Throttle, Prop, Mix ) controls on my PFC cirrus II console USB. They simply did not work at all. My computer sees the throttle body just not FSUIPC 5. After digging all the files and verifying them with P3D v3 version file which worked, I figured out the problem and wanted to share with you and other members. The AXES part of the install was missing in the FSUIPC.ini file in P3D v4 modules folder. You can see it below, you might want to update the FSUIPC 5.103 / PFCHID 1.49 / PFChid64 to include the axes part of the controls. I simply just copied the Axes portion from my P3D v3 modules FSUIPC v4 to the FSUIPC 5 for P3D v4 and now works great.
