Thanks for this analysis. I have had similar misgivings, but you describe it a *lot* better than me.

This is one reason why I am skeptical of what the SG reports when someone applies the "IAT Resistor Mod" to fake HAI temperatures to the ECU/PCM. I think the SG relies on the IAT temp, but the ECU/PCM mostly ignores the HAI during closed-loop operation. Garbage in, garbage out.
