Reprogramming F31 computers as F30? (trunk pop, power sun shade)

[TouringM3]

Hey Coding Gurus –

I'm putting the parts car together – effectively everything (harnesses, computers, interior, driveline, etc... – from my F31 LCI into the F80 chassis.

So far stuff works darn well, except I can't get the trunk release to work, and the car isn't coded for the power rear sunshade.

(Yes, i ported over all of the wires into the harness in the right pin locations)



Anyone have advice on either adding "415" into the system - if that is even possible on a F31, or reprogramming my car to behave like a F30 so it can accept the power rear sunshade, and be setup for a non-powered trunk lid?



THANKS!!!
