So, all of my enabled monitors with the factory ROW tune were "ready" during testing with no cats. However, it will obviously not pass a smog test.
Im confused by this, but probably just because of terminology. To me, "smog- check" and "emissions- testing" are the same thing. Both terms refer to testing, without distinguishing method of testing.

Is that how you're using the terms?

If so, then the ROW tune won't pass a plug- into-obd2 test in your county in Texas?
