tried the items in this post, however could not do percussive test or calibration on my unit could not find in settings or diagnostic menu.
could not change ACM values as i don’t know what to try and change.
tried master reset, tried downgrading to other versions, even 3.3 ones, tried a different apim on older version and still no go, so this tells me its not apim related.
one thing i dont understand is how software can change an as built i did not think that is possible, but it seems the update changed somthing in my ACM as built maybe???
