Good question. I suspect it’s kept in the processor. The cluster has to be a lot cheaper cost than the processor -that has its own serial # and is tied to the VIN of the bike it is on. I would be supprized if it were otherwise. I know this doesn’t answer your question 100% positively. I’m sure someone with the correct answer will chime in. I bet the guys at Fuel Moto know the answer for sure.
