    Changing IAT specs

    I have an aftermarket IAT sensor. The link below shows the calibration info for it. I have found the "iat sensor curve" in hptuners software but am not sure what the values mean. I'm sure the temperature values are based on Fahrenheit. But, what does percentage mean? Is that supposed to be ohms of resistance or am I missing something? I need to figure out how to set it up for this sensor.

    What year/model? Use VCM Editor. Edit>Navigator and type in [filter text] intake air temp and it will take you to your tables. Interpolate across mising dat...its not 100% accurate to interpolate but will be close enough.

    The computer is out of a 2000 suburban. I have it in my lq4 swapped 240sx. I'm not understanding what that table shows exactly. The number I can edit looks like the temperature itself. How am I supposed to figure out what values to put though since it's based off resistance?

    11/26/17 update -- only input to the yellow cells. DO NOT input to the Amber cells as they contain formulas and calculated values used throughout the tool to arrive at the new table.....
