N52b30 euro2 software flash!

Hey guys! Happy new year to everyone! i've recently swapped my N52b25 to N52b30 engine. I've flashed my old b25 ecu to new software from b30, now it all works fine, but ive been told that there's EURO2 software for MSV80 with rear lamda's switched off and without rear catalytic converter .



I cant find number of this software, can some1 help me?



Also, can anyone confirm any performance raise or fuel economy with this software?



I've got e93 2008 Europe.
