Hi guys,
I bought into my girlfriend X1 2014 16sDrive (because another wasnt) now I want to two things:

1. i bought Tempomat (Cruise control) whole - Switch unit steering column 61319169759
http://www.realoem.com/bmw/enUS/part...&q=61319169759
when I install it to the car, it must be coded, is it true?

2. this is the same motorization like 18xDrive, can i swap the ECU, make the car behave like 18xDrive?
other, more powerfull version of N47D20C motors (20,23,25) have another injectors

Which sw + hw can it do?

I have an e46 but is more powerfull and does not had to code when installing a cruise control.

thank you
