@airtex2019 Hello
Well, all clear airtex2019, thank you very much
IĀ“ve understood the function of set AB and set Idle (my mistake).
I had assigned a DX button in Cougar throttle as Set RightThrottle AB Detent, then each time Cougar gone above I had the famous message.
IĀ“ve deleted both assigments in BMS (Idle and AB detent) and now all works fine.
Once again, thank you very much, airtex2019 š šŗ
