Dear Members,
I want to test IAT input with 10K trimpot, but I have no response on Tuner Studio,
Do I miss something in the code or configuration ?
I can not test CLT and IAT with trimpot but TPS works well
Thanks

You probably have it connected incorrectly.
Or you have set the wrong board in TunerStudio in Engine Constants.
CLT and IAT go to ground and sensor input.

Or the IAT/CLT calibration values don't match the trim pot values.

Any clues ?

How to calibrate it ?
Trimpot pin 1 = 5V ,2 = A0 , 3=GND

In Tunerstudio.
You need to read the wiki.

Calibrate temperature sensors.

I use 10K trimpot,
Does it mean Bias Resistor = 10000 Ohms ?
I experiment with Mitsubishi value...2490
