Pre-takeoff checklist
Has anybody ever done a firmware upgrade on this instrument... Or perhaps an engine change? I am interested in the procedure.
I have done several on my JPI 830 several times. You do want to record all your current settings in case something goes wrong.
Did you keep the same model engine or upgrade?I recently changed my engine and asked JPI if I could zero out the hobbs. Some of them, yes, older units, had to send back to JPI.
Mine was older, so I didn't do anything.
