    Air Intake or Air Charge Temperatures!

    Hello,
    Is there a way to scan for the air going into the motor after the supercharger on W bodies? I looked and cannot find the PID. I know the V8 guys have this option.

    No, there is not an IAT sensor after the supercharger

    Hmm. However, I wonder if there is a PID for Charge Temp (not IAT Temp)?

    If there is no sensor it would have to be calculated.

    I have read of such a calculation, thats the reason I brought it up.

    Involved IAT and engine coolant temp, and a bunch of others things I just cant recall right now.
