There was a long thread over at CF about this, USAF Pilot's car (?) had a CCM go down. The only thing that stuck with me was it had to be reprogramed, but you already know that, within a specific time period upon start up(?).
I think there was also a model year backwards & forwards compatibility for swapping in kind of like the rules of thumb on the ECM swaps....I think.
I should have paid more attention, sorry Dom!
