Thanks. I think I have a bad EGT sensor on cylinder 2. Looking at the engine data for the almost 2 hour flight, the oil pressure was 88 in the first hour then at full power in the 2nd hour it was usually 86. Sounds like the consensus is that it is OK at that reading. It's amazing to be able to go back and look at the incredible amount of data provided by the AFS equipment.
Both CHT and EGT look wacky on #2, at least at the moment the photo was taken. Yes, the data logging is a great feature and really offloads you on the test flights.

We normally set the oil pressure to be 70-80 psi, for cruise RPM, in the test cell. Yours is a bit above that but you are also running at a higher cruise RPM. I would check the integrity of the pressure reading and if accurate I would turn the oil pressure adjustment out 2-3 turns and see what that yields at 1400 rpm with above 120 f oil temp on the ground. When the pressure is set to 60psi, by adjusting the relief valve in or out, at 1400 rpm with the oil above 120F, on the ground, the oil pressure at cruise with 180F oil temp will be 75psi, which is the middle of the green.
Happy New Year,

How would I go about checking the integrity of the pressure reading? So good to hear from the Mattituck expert!!! Thanks Mahlon
