I've got a D-180 that says I'm going 25-26 kts when I turn it on, or if I turn it off and back on, it may say 0 kts. I've zeroed it, but it still seems unreliable. Sometimes my AS and or ALT will freeze up. My engine RPM's also jump around sometimes going full RPM or even to 0. And of course nothing would be complete without my compass after several calibrations an programming in the intensity? and mag var? (read the instructions, entered what the web site said) the compass drifts all over, and yes, nothing is near the compass unit, and the hardware has been changed to non ferrous material. Engine temps are nice and steady as is the fuel readings. My pitot is connected to the Dynon Pitot/AOA non heated pitot probe, but the altimeter is connected to another (OLD) probe. Looks like the Dynon Pitot/AOA has a bent AOA tube? Not really sure, but it isn't being used for a reason. Did go over the tubing from the probes, no leaks, no blockages. Any suggestions?
