Airbus PM/CockpitSonic - unable to have smooth thurst during taxi

[guda]

Hello,

My friend owns an A320 cockpit based on Project Magenta software and CockpitSonic hardware

During taxi, at IDLE position, if we move throttle, it straight grows to CLIMB thrust. It's impossible to have a fine thrust.


I had a look on a320.exe from CockpitSonic to calibrate the handles. The values seem OK

From PM, the throttle indicator confirms that the handles straight move from IDLE to CL without intermediate positions.



Do you know what happens?

Thank you for your help

Dan
