In HP Tuners the mapping is confusing:
  • IAT Sensor Cal = MAF temp sensor
  • IAT 2 Sensor Cal = TMAP temp sensor (there is no MAT table, they should really fix this to remove the confusion)
MAT = PID 2737
I am going to politely disagree with you here.

On the ZL-1

IAT1 is in the MAF
IAT2 is in the TMAP
MAT is a calculation as I mentioned above.

MAT refers to IAT table for timing adder or subtractor.

On the SS,

You only have IAT1, even if you move it to the blower.

MAT is a calculation taking in to account all the things I mentioned above.

MAT refers to IAT table for timing adder or subtractor.
