For some odd reason my scanner reads all GPEC2A equipped Vehicles IAT reading -83. Does anyone have any clue why this is happening and if so please let us know. Is HP tuners even aware of this issue with their scanner software with these specific PCM's?. I've tried both the latest version and the latest Beta version, both yield the same results with a reading of -83.
I have a GPEC2A controller in my 2015 challenger and the temps read correctly. You have a sample log we can look at? Better yet, did you submit a support ticket to HP?

Sounds like you need to repoll for supported parameters and choose a different IAT channel.
Hey, thanks for the replies. Yes, here is a data log.
I submitted a support ticket about an hour ago. I hope to hear from them by the end of the day.
Just looked at your log. The SAE Pid looks correct to me. Try logging when the engine is cold and note the ambient temp, if they agree then stick with SAE.
