Not surprised. CA has already been sending cars to the ref that had passed a previous smog check with an ECU flash. If the CVN(basically a checksum of the .bin file in the ECU) isn't the expected OEM value they will assume it's flashed. This check has been done retroactively, but now it will be during the actual smog check, which is more convenient. Dealing with the referee is stressful.
I'm sure it's only a matter of time before someone comes up with a workaround.
