I just wanted to mention that Toyota is still recommending replacing the ECU to this day.

So whatever is issue is (maybe just a known defect in the early production ecus) they still replace them, maybe it is just being over cautious on their part.
I have a general knowledge of MCU/embedded development as well and what you are describing is what I would have thought as well. If you overwrite all of the flash and remove power to kill the ram you should have a completely fresh ECU.
I will take your advice though and just leave the old one in there with the new firmware B01C after getting the cam work done and see if it works. That will be easier because I have an ecutek license on it anyway.
I ordered a ECU from a '15 off eBay earlier though. So if I do end up using that should I flash to the '13 firmware (B01C) or just leave it at the '15 firmware (whatever that is, but I think I noticed it was different in ecutek).

Their being pretty nasty denying warantee claim due oil cooler for a known defect that has numerious tsb covering it. and denying you a new ecu if the old one is faulty well id ask them to explain how the oil cooler damaged the ecu.
Yes it will be best to put the original b01C firware back in the new ecu, with ecutek you going to need to get the tuner to renew your ecutek licience for new ecu.
