MAT temp vs MAT table (S_AUJP)

[34blazer]

its an IAT sensor I just used the MAT to identify the table. IAT functions as normal. if i use the datatracing to adjust value in VE table, like idle for instance, ill change the cell the is highlighted. the cell that is highlighted(by the datatracing bubble) is the actual cell im adjusting, no descrepancy. for the MAT table the cell hightlighted by the datatracing bubble doesnt match up with the corresponding value in the next cell directly to the right. i have to guess and its usually about 2 cells higher up in the range. im going to try and get some pics, seems like no one understands what im asking LOL. i need to work on my engrish

*edit* since the readout from the IAT is non linear it uses the lookup table, engine off and cold, the value seems to closely match ambient air temps. now for the equation in the XDF, it uses: 1.000000*X+0.000000. does that seem right?


*edit2* just looked at the ANHT hac and found this(below). not totally sure what im looking at lol
