When it gets smogged, they will know if it's not a California-legal calibration from the Certification Label and/or the Emission Compliance Label.
Before you bring it back to California, you should look into the possibility of an exemption, assuming that you are active duty military assigned outside of California. This has surely come up before and they should have a procedure for dealing with it.
