Anyone know the offset to change the tempature from C* to F* on my sensors like IAT, coolant, and etc. in Tunerpro? Searching keeps pulling up timing stuff.

 

Standard conversion is

F = C*1.8+32

But on the 7747 ADS file I did, the CT temp in *C was based on a table. So I just made a second identical table and used the "Covert C -> F" feature. If your ECM is similar, and *C comes from a table, that's the easiest way to get what you want that I could find. It seems there is no straight forward formula to get from "counts" to *C or *F, and I couldn't find a way to apply a formula to the output of *C lookup table.
