Experimenting with Intake Air Temp. Request for comments.

IIRC, the ECM starts pulling timing advance when IAT gets above 95°F.

Yes. The ECM uses the temp sensor in the bank 1 (right side) MAF and that is what you see on the ScanGauge. I wouldn't be too surprised to find out the sensor data is massaged a bit before being reported, but it should be close to what the sensor is seeing.
