I am about to install my D100 and have it wired up on my bench. With the unit turned on and the pitot line connected, the AOA line plugged and the static port open, if I blow in the pitot line to get about 100 mph indicated, the dynon shows a nose dive of about 40 degrees. If I plug the line to hold 100 mph indicated, the nose slowly comes up to the horizon after about 20 seconds. Also, the roll is off about 5 degrees and takes longer to straighten than the pitch. This unit is about 6 months old and has original software/firmware. Is there somthing I am doing wrong? Thanks. Michael
