This is all the original dealer should've changed. I'd bet they shorted something in the unit attempting to reprogram it that is causing the issue.

The used car dealer in the Buffalo region that I got the car from seems to do a decent volume in imported Canadian vehicles. They have a speedometer shop that they use on the regular to do the km > miles conversions for them. They did mention that certain brands can be problematic, Toyota among them.
Canadian cluster for 2015/2016 MT: 85002CA450
US cluster for 2015/2016 MT: 85002CA430
I believe that the US and Canadian ECMs have different part numbers as well.
I can see how programming the Canadian cluster could have shorted something in it, but the fact that the US replacement cluster behaves exactly the same way makes me think that the issue is external to the cluster hardware. Unless programming the US cluster with the correct mileage damaged it in the same way as the km > miles conversion programming hypothetically damaged the Canadian cluster.
Is that image from the BRZ service manual? I will definitely bring up the main body ECM customizable settings when I go back to the Toyota dealer with the US ECM. Thank you for that.
Edit: I'm looking in Techstream for the 2015 FR-S and can't find documentation about main body ECU customizable settings, unfortunately. This might be something that only Subaru's dealer software can do.
