what emission control circuits are you talking about?
I borrowed an 03 USDM ecu, flashed it for my injectors, turned off all tgv related codes and forced readiness to pass NJ inspection. Its straight forward and should be very similar testing in NY state.
Note, the rom has to match the ecu, you may get some weird fuel pump controller CELs if there is a mismatch.
