I am selling an Electronics International UBG 16 Ultimate Bar graph engine analyzer. Worked when removed. Have the connectors and harness for this but I did not show it in the photo. Does not include probes. This unit sells for about 1500 new on Aircraft Spruce. I am selling it for $600. This unit can be sent in to EI to be re calibrated and programmed for your aircraft. I originally acquired it to add to my panel, but plans have since changed!
