550 ECU on 545?

Does anyone know if it would be possible to move a 550 ECU onto a 545? And if so would you get the performance benefit from the 550?

You know the n62tu in the 550 has .4 litres more displacement, right?

...and different intake manifold control systems, and different oxygen sensors, and different MAF sensor. It might even lose power with the 550i DME CM on it....

Yep, the 550 N62TU has a simpler, 2-stage intake manifold compared to the more complex infinitely-variable version on the 545. The secondary air ports were also deleted on the 550.
