We have KenneBell Stage 2 Supercharger kit and Cold Air intake with filter in the bumper. But strange thing occur, we looking to ECM scanner and see IAT numbers kinda 60-70 C during idle even, sometimes we were able to see it even as high as 75 C, actuall air temp on the street is about 5 C only. Any idea why it can see so strange numbers??
Where is the temp sensor located?
If one is in intake manifold, it's quite normal.
I'm not really sure which one does vcm scanner reads? Could it be sensor from intake manifold or maf sensor may be ?
From the factory on this vehicle, there is only one air temp sensor, and it is part of the MAF sensor. When you put a blower on, the air temp sensor needs to be relocated. If it is a centrifugal blower setup, its easier to just put the MAF after the blower so you are reading the correct air temp.Quote:

That's looks like we have second type of setup and iat placed in the intake many, since maf 2 wires are cut. So that temps looks normal for this case, should that placement of iat sensor must to be noted in the PCM software? I just trying to make sure everything in the our PCM inputed right except fuel and ignition maps... Or may be we made some mistake in our calibration file
You need to make new iat spark table.
