On the ground - in the hanger - EFIS says we're doing 29-31 KIAS!

I just did the backup / upgrade to 8.8.35 / restore sequence today. Don't know if that might have fixed my earlier problems.
Either way, I have the latest software available and a configuration that works for me!

Before changing any calibration of the EFIS be sure you are not experiencing blockage of the ports / tubing by removing the lines from the display and verifying smooth flow with something like a large syringe. Place some tape over the hole and then ensure you achieve a vacuum without leakage before concluding that the EFIS needs calibration.

Shawn makes a great point here - I had taken mine apart and bench checked it before I even asked.....
