Auto throttles smoothly forward / zig-zagging backwards

[Saldo]

With AT om the throttles move smoohly forward , but when hey have to move backwards half of the time they go like 3 inch backwards /2 inch foward/ 3 inch backwards / 2 inch forward etc.
After several times they move backwards to their position.
Sometimes ony one has this behavour.

By hand the throttles in Fs move perfectly.
Also with the Phidget Control software.

All suggestions are welcome.

I found out that it is because the Ifly AT reacts on throttle inputs when they are being moved .

Fs2Phidget needs to read the throttle positions so I cannot disconnect the joystick card in AT mode.

The default 737 AT has no problem with throttle inputs. So using that gives smooth moving throttles.

What helps is when I turn the speedknob slowly in the Ifly.
Turning it normally make the onscreen throttles jump forward very fast.
And then my hardware throttle also jump forward , cannot brake fast enough, jump back etc till the new correct positions.

A solution could be if the Ifly onscreen throttles would move slower and not from idle to full in 1,5 seconds.

Anyone knows if in the airfile or aircraft.cfg file this can be done ?

With the help of the Flight1 team the issue was finally solved, simply by installing Fs2Phidget on my client....
