First, I would ask to see if they have any information to why the ECU now needs to be replaced?
Second, while your G37 is already at the dealership then I would link it back to the TSB update for the TCM and while it's there, just get it done.
The TSB should give them all the needed information on how to handle this issue. My dealership here had no problem in correcting this. I just hope that you don't spend too much time dealing with them, and just be specific on your approach and I would push for more information due to your issue.
Hope everything goes well for you
