After reading that the Canadian fix works better than the US fix, I see no sound reason for disallowing the Canadian fix in American cars. If it takes a brief ULEV violation to prevent an annoying or dangerous hesitation, it should be allowed. The average pollution rate is what should be taken into consideration. If the US government can allow high-pollutin' Hummers and carbon-spewing diesel-powered behemoths to roam the country, why can't a fairly fuel-efficient V6 Lexus be allowed the brief violations needed to allow it to shift properly?
