You were right Tracy, something was not right. My helpers ignored P2-21 pin. After couple of hours ringing all the wires and not finding #21 I opened the connector and pin #21 was empty. Now is all fixed and the temperatures show right.
Next is my oil pressure problem....

Something is not right.  Make sure you connected the sensor return line to the OAT bias line instead of ground like the other air temp sensors.   OAT is different because I wanted it to be able to read down to at least -40 degrees F.  It is not calibrated in C although it should be possible to do that if you wanted.  
 
After double checking all wire connections to it, let me know what you see.  The unit is tested with a bench reference sensor on the OAT function so I'm fairly certain that the unit is working but it is remotely possible that the sensor is bad.

Hi Tracy, I connected OAT sensor today, but the display shows  single digit
number 5-6. When I blew some hot air with the hair dryer on  the sensor, the
numbers climbed to 11 and than settled to 5 after removing  the heat? I
wander if the reading is in  Celsius?
