Just found out Logitech’s X-Plane Plugin for FIPs has been updated to version 8.0.213.0. According to the support page, the new version has included additional Cessna gauges (similar to those offered in FSX/P3D Drivers) plus updates to the rotary dial behavior in gauges.
Not sure what “updates to the rotary dial behavior” means but the new version works fine on my system without any issue so far.
Sadly, the fuel-flow issues I reported more than a year ago in Post 505 and 509 are still not addressed.

I an dabbling with X-Plane 11. Where are the .xml files located for the FIP gauges? Thanks!

Hi Brian,
The FIP Gauges file for X-Plane are stored under: X:\X-Plane 11\Resources\plugins\XSaitekProFlight\Data
