New importer update just released.
You can find new fixes in Engine tab for turbines – idle and high RPM percentage values, they are positively affect stability of the engines (thanks Technotech for the tip).
Also in Cockpit tab (Full import mode) single RPM or TORQUE gauge will be highlighted depending on current engine type, do not insert both or engines state of your turboprop/jet plane will be not visible (reported by maxx2504/Micha). Cockpit section insertion will always set default values without request.
