Thrustmaster Airbus Throttle calibration guide?

I have the Thrustmaster Airbus Edition Throttle Quadrant, and it mostly works great (not having any detection or mapping issues like some i’ve read about) but for some aircraft the throttle range is way-off, for example in the TBM I can only use about the 1st 1/4 inch of throttle travel before the game reads it as fire-walled, which makes fine tuning very difficult. I haven’t been able to figure out on my own how to adjust this…does anyone have any ideas or know of any guides? I’ve posted this in the Thrustmaster forums too, with no reply. Thanks very much!
