Engine doing funny

Hello Guys
I'm trying to fly a turboprop. I have Flight illusion GSA10 interface with analog potentiometers connected to it.Left engine is working fine. Right one give variations in RPM
even when not touching pot. Variation is more than 10%-20% ?
Pots are same brand and same value. Could it be because cables are not shielded ?
Any idea ? :?

thanks and fly safe

Gerry

Absolutely..

Check in FSUIPC. do you see "The Jitters???"

That could be it for sure...

1. Did you calibrate the joystick?

2. Make sure that if you tell FSPUIC to handle the joystick axis, that the axis is removed from the joystick assignments in the MSFS joystick assignment settings. Otherwise the 2 program will fight over the joystick axis. Had this problem the other night.
