Mixture controls

I am setting up a 4 engine generic sim, with 4 mixture controllers and 4 engine start/cut off switches. My question is this:

How do i change offset 0890 from digital (off and off, to be able to track with the movement of the mixture handle? the only thing i can do is bring the sensor to 0 and it will shut off the mixture, but then i cant bring it back.

Hopefully i follow you correct...

You can assighn joystick axses to mixure controls--same way as throttles

My mixture controllers are set up through the phidgets..

Sounds like you might need an analog axis input card.

Maybe a Phidgets user will pipe up here shortly.
