Temp vs Voltage table for anyone logging IAT

[Jack B]

In order to get accurate IAT while logging you need to correlate the true temp (what pcm sees)with voltage (that pcm sees), if this can help anyone here are the values.

Temp Volt
43 4.39
46 4.33
50 4.27
55 4.18
59 4.12
66 4.00
70 3.90
75 3.78
81 3.67
84 3.57
90 3.45
95 3.29
100 3.16
106 3.06
111 2.90
115 2.78
120 2.67

i will need to do the same thing with the SRT IAT sensor, as well as the oil pressure and TPS sensors...

[99 R/T 10]

Is this temp read at the front air sensor(in the airbox)?

Yes, it is what the pcm uses to adjust the a/f.
