Honest question. If it truly is a software problem, the "fix" would be an update

track junkie in this thread confirmed his BRZ that had a build date of Feb/13 had the updated calibration file. His car is in the States.
I think where it gets confusing is that there does not seem to be a TSB or Bulltetin (at least for Subaru) where it points to this issue that you can refer to when you work with your dealer. We just have the ZA1JA01C calibration file with this description:
Known Changes/Fixes: 1. Changes to transient spark control to resolve failing (direct) fuel injector seals caused by excessive detonation when changing gear at high engine speed (above 5200rpm).
I am not sure if that is enough information for a US service department to update your ECU without pointing to a US bulletin or TSB.
