OAT sensor reading ~50c low

Since getting my D10A back from repair my OAT is showing -26c on a 28c day in the hangar. Any tip on troubleshooting?

If I had to have a stab at it, I would say that when your D10A went for repair, they have upgraded the firmware, so now the D10A and the EDC have different firmware versions.
Is your compass heading making sense?

Thanks for the tip, I'll check the compass next time I'm at the hangar!

Turns out was the sensor type in setup. I thought the option of "0", "1", or "2" was qty. Wrong.
