Problem solved. For unknown reasons it didn´t install B48.1 on Server PC and kept B48.0 there. Now working!
EDIT: to be seen at first glimpse: "IDLE" back - JL, THX for the updates!
EDIT2: In EIS2 mode "IDLE" is flashing initially and as long as I pull to idle coming from forward thrust. Only when I push the levers coming from Reverse Idle "IDLE" shows up non flashing. I that normal or does that mean the TQ is not properly calibrated? TQ is from Skalarki.
