I did a search and did not have anything jump out.

Is it possible to write a program for the CH Pro Throttle that will push and release a key when the throttle is at 100%. I am trying to incorporate the AB on and AB off keystrokes for EF2000 into the throttle so that the AB will kick in when the throttle is maxed.

Any help would be appreciated.

Sorry I don't have a CH Pro, but this might help anyway. With the Saitek HOTAS you can change a rotary control into 'bands'. You can set as many bands as you want and allocate a key press for each band. So for throttle I can set 12 Bands 0 being min throttle, through to band 12 which is AB.

Hope this help you

Yes. Use a CMS script.

Just assign a CMS button to turn on when your throttle axis value is greater than whatever % you want.

Exactly, just like this. I'm sure you can find a specific example of this at the CH Hangar; look for IL-2 examples with WEP - this is the exact same implementation you want.

Yup
