that's a odd one.. I have seen key on iat saved and used as part of the startup routine to avoid heat soak rich cranking. but nothing you'd need to know or see as a monitor.
weird mostly useless pid to be able to display. most consumer grade stuff avoids options like.
its ridiculous getting anyone useful on a phone or even tech line anymore. you might have more luck with a email sent to their tech department if you can't find it. that way when the tech line guy has no idea, he might take the 2 secs to forward it to an engineer. if he's interested, you might get a reply but probably not either.
glad you found it wasn't a wiring issue after all.
There are some PIDs I can look at that are very clearly "commanded" values (it's even in their titles). I suppose it would make sense that 32-degrees is an intentionally false, commanded value for cold cranking purposes--tune or stock--and I have noticed that my fuel trims do start rich with close to a 1k rpm idle that calms down to where I tuned it (650rpm) within 30-60 seconds.
Without having spoken to anyone from the manufacturer as of yet, it seems to me that the data values and PID names are mismatched; 32-degrees would make more sense as the "Power-Up IAT" value, and the live (accurate) temperature reading as the "Intake Air Temperature" PID. Whether this is a glitch unique to my product or a general "feature" is something I would like to know, when I finally catch someone on the phone. We shall see. In the meanwhile, yes, I am glad my IAT wiring is good and that my tuner/scanner is at least reading accurate information (regardless of its strange categorization in this case).
One of the next hopeful items on my agenda: re-looming, re-routing (where appropriate), and re-attaching the engine bay wiring to where it belongs or would be better off. So, perhaps I didn't *entirely* waste my time learning a few things in that area.
