Does anyone have a guide as to setting up the unit to use the left most lever as the speedbrake? I had it working good on the right lever, then tried to change it 

I had it to go to full up when pushing down on the lever, then if I wanted it to partially deploy I just raised it to where I wanted the spoiler to be at. 

I tried to set it up in reverse too, as with the throttle lever, but it won't work. (Throttle and flaps work ok...)

FSX, (no Saitek software installed)   

Any clues?
