IAT sensor calibration?

Is there a table or tables you need to adjust for different IAT sensors or are they all the same? I need to make sure the data in the tune is correct for my IAT sensor. I was running a 5-wire MAF with integrated IAT then switched to SD and deleted the MAF and bought an IAT from 1998 Camaro 5.7L part#2ATS7 and installed with a breakout harness. I have a ls1 pcm out of a 2002 camaro sport coupe.

I can't really find any tables that allow you to adjust IAT Temp vs IAT voltage. The only tables I see with IAT are the Spark Advance.

Thanks for any clarification.

The CLT and IAT have the same resistance curves and they haven't changed for quite some time. The 98 Camaro sensor will work just fine. I use the external IAT Corvette part and get the grommet at the same time, but the F body one is the same IIRC.

Mmmm well... I went from '99 LS1 to a LS3 with a card type MAF and the curve definitely wasn't the same, and it did make a difference.. Below, where the IAT cal is in my 99 ECU... :)

LS3 is not a Gen3. Gen3 sensors have the same resistance curves as those from the early 90s.

That is what I was assuming, but I like verification lol. Thank you.
