Logitech G940 and FSUIPC

I'm not entirely sure how to get this working on the throttle. I've tried setting it up as the reverser in FSUIPC, however it doesn't do anything when I pull all the way back on the quadrant. Am I supposed to be using the logitech gaming software alongside it (right now I have it disabled as it seems to screw up any settings in FSX). I've got decrease throttle set to a button on the throttle for now, however I'd really like it integrated into the the quadrant for that extra added realism. If anyone has some experience with the G940 and wants to shed some light on their settings, that'd be awesome. I'm using FSX, btw.
