IAT Sensor Calibration

I am using a GM MAF sensor (Pt#15865791 which has the integrated IAT sensor. Also using 100mm housing) in place of the original MAF sensor and IAT sensor that came on my F-Body. I am wondering how to address the IAT Sensor Calibration table.

Within HP Tuners
Engine Diagnostics-->Airflow-->IAT Sensor-->IAT Sensor Cal

Does this table need to be reformatted? If so, how would I go about doing this?

Thanks

I would first check the reading's threw the scanner and if it seems way off as in ambient outside temps are 90* and it is showing 75* IAT then it is probably not right..

That would be a clear indication. Although I'm curious about the method of getting it to read the exact temp.

I would look up what vehicles that MAF came with and dig up a tune from the repository. If you want to validate it I would use one of those BBQ grill temp probes next to the IAT and your wife's hair dryer. But I seem remember the old f-body IAT cal table looking really weird, like temp VS percentage of something.
