Hi Uefly,

I agree with comments presented and in addition you may want to raise the Deceleration delay to slow the RPM decay for a bit longer in the dive.

The ECU Deceleration default is generaly 15. Raise it to 20 > 25. This will help as well.

I have experianced this condition as well and it was traced to an air leak in my UAT. This was due to the UAT leaking air at the CAP. Removed the cap and placed more Teflon thread tape on it, rpelaced the cap and....no more issues.

Bottom line, If you can confirm that your UAT was FULL when you landed, this is likely not your cause.

While your conditon may be one or both of these, if your flying in cold weather, condiser evaluating BOTH conditions if your suing a UAT.

Best Regards,
