I believe you when it comes to BRZs. Toyota Techstream does not have a main body ECU procedure to localize the car for various markets however.


An experiment I would have liked to run is to try an un-reprogrammed US gauge cluster in my car before I had the US ABS controller installed. Maybe it would have worked.


Knowing what I know now, that's what I would try first.


The US and Canadian ABS controller ECUs definitely have different alphanumeric markings on them. Whether that means that they will work only with their local gauge clusters, I cannot say definitively.
