This (from Bill's post) is the problem:

and we won't know if it's really being used until the technology reaches smog stations.
Subaru will/has supplied a list of calibration ID numbers and, for each calibration id number, the calibration vehicle number to expect to see if the ECU hasn't been tampered with. I imagine that Subaru dealers have this info, too.

What my little experiment would tell us is whether or not Cobb's reflash does anything to short circuit the CVN calculation or reporting so that a reflashed ECU continues to report the pre-reflash CVN value. If not, then there's a problem.
