The Air Data Modules are the interface with the pitot probes. They convert dynamic pressure to a data bus. I don't know, but there would be the logical location for correction calculations. It's done in the Air Data Computer in planes without ADMs.
Thinking about the amount of fright testing needed, it's kind of surprising there would be more than one maker of pitot probe certified. Is there more than one on Boeings? The 737 doesn't even have a choice of engines..
