Did you manage to program the PCM so your ford knows there is a new differantial? If so can you tell me how?

I read in these forums that somebody was asking about changing his Ford Fusion 2.0 ecoboost Awd rear differential. Some guy called Omar stated that if you change your RDU you need to reprogram it through Forscan?? Does anyone has an idea how it's done? It seems unreal to me but I am sure if it's done someone has an idea how..
