Oregon doesn't even have a statewide DEQ requirement, and I suspect it never will.

Oregon follows California emission laws but does not test statewide. They do test biannually in Portland and Medford areas. It’s not 100% statewide in California either. There are few exempt counties.
Whether or not other states follow Californian in looking for ECM mods is still TBD.
