Calibration output doesn't go below Zero 0

[yankeeclipper]

When I go to the calibration dialog (Cowl Flaps, e.g. but same regardless of axis assignment) without hitting the "set" button (Axis not processed) the input still matches the output.  +/- 16k.  If I hit "set" the input is still full range but the output will only vary from +16k to zero.  No negative values in output.  This means FSUIPC calibrates to the top half of my device only, the bottom half of my input device is unusable (a lever, in the case of my Saitek quadrant, though same result with Bravo Quadrant).

I have tried various settings such as mapping to FSUIPC calibration and to FS as normal axis.  No change there.  Same with "Filter"

I am using: Alpa Yoke, Bravo Quadrant, Logitech Radio Panel, Saitek pedals and Quadrant.

This depends on what axis control you are assigning to. For the Cowl Flaps, from the MSFS documentation:

COWLFLAP1_SET	Sets engine 1 cowl flap lever position (0 to 16383)	Shared Cockpit
COWLFLAP2_SET	Sets engine 2 cowl flap lever position (0 to 16383)	Shared Cockpit
COWLFLAP3_SET	Sets engine 3 cowl flap lever position (0 to 16383)	Shared Cockpit
COWLFLAP4_SET	Sets engine 4 cowl flap lever position (0 to 16383)	Shared Cockpit

So those axis only accept values from 0 to 16383. There you calibrate so that a -16383 input sends a 0 output, and a 16383 input sends a 16383 output (and a 0 input would send  8192 as output).

No. It means the whole axis range (-16383 to + 16383) is calibrated  to send the full axis range of 0 to 16383.

No.  It means that I need to enable "No Reverse Zone" so that the mappings don't get confused and map the minimum value with things like IDLE.

Sorry, I don't understand. What has this got to do with, for example, Cowl flaps? Reverse zone only applies to throttle/thrust.
