Help with Logitech Extreme 3D PRO with Ace Combat 7

I've installed X360CE and gotten the game to work with the stick and map all the buttons, but a problem persists. I can't get X360CE to behave in relation to my slider (throttle). In Ace Combat, the left trigger is the brake and the right trigger is the throttle. Left trigger functions fine across it's entire axis, but right trigger's axis only encompasses some of its total range. I've used this stick with a lot of games over the years with no issues like this that I could notice. I assume I just need to fiddle with X360CE enough to get it to recognize right trigger's full range of motion. Any help with this would be appreciated.
