    yes it was showing 200 varying from 120-220.
    it was not hunting up and down, in fact it was quite steady at 20 feet below set altitude.
    what do you recommend?

    We need to find out from TruTrak why it is not climbing when we are sending a command of 120 to 220

    yes thats what i don't understand. if the efis commands a 120-200 foot /min climb why doesn't it climb back to the set altitude and see a 0 ft/min/
    also i don't like it busting altitudes in a descent.

    If the ALT gain is too high it will bust altitudes.... Put it back at 5.

    Rob,
    Flew today with your AP/EFIS settings. Lost about 50 feet in heading mode with a 90 degree turn. Efis showed between 100 and 330 ft/min.
    in level flight altitude was about 20-30 feet low with efis saying 100-120 feet per minute.
    This is a bit better than what I had before.

    I
    have noticed that my altitude usually runs 30-40 feet lower(always lower) than what is in the EFIS. When I hit check it shows the EFIS is telling the AP to climb at 120-170 ft/ min but nothing happens. all i see is the altitude staying and 0 fpm on the vertical speed. Why is the efis telling the AP to correct yet it appears the AP isn't making a response.
