Probably for certain country emission standards. They probably just said it was the same N54 as used before... so no new certification was needed. I think BMW pulled a fast one! We all know the 1M's engine is really a factory tuned engine. Different DME, different higher flowing cats and secondary cats, and it has the PPK hardware too. So its understandable that maybe BMW played with the rules a little bit!
