I hear occasional rumors that the dealer / Tech II can tell if the newer ECMs (E92 etc) have ever been reflashed. Anyone know if this is true?

Yes it is true, GM have been able to do that for a long time on many ECM types.
I no longer monitor the forum, please either post your question or create a support ticket.
