All of the other sensors seem to be working properly but no matter what, the IAT2 reading is always at -40F on my KTuner. Bad sensor or maybe not seated correctly? I know IAT2 is post-intercooler, but where exactly is this sensor?

Bump. Same issue here. Has anyone found a fix for 2025 Si not showing IAT2 Temps on Ktuner V2?

Confirmed with my Snap On scanner that IAT2 temperature data is available from the data stream in the 2025 Civic Si.

This is a Ktuner issue, and they told me today they do not plan to take the time to fix this. Sad.

I noticed this today, but my generic obd scanner shows proper iat2 temps. Ktuner obvious dont give a sh1t about their customers.
