Hi,
I have an Orbit ECU 3.2.
It worked pefect.
Now when I set a new min and max rpms at next start the calibration can not be complited and the tubine rpm ges up and down between 125k and 114K nonstop. And display showes Cal.
When it goes to max rpm I saw on display 128K rpm one time.
If I set max rpm 80000 then it calibrates ok with no problem.
I already contact Orbit and they told me that the problem is possible double reading couse of spinner and it need to be painted, but no resoult.The same story.

Do you have any suggestions?
Thank you!
