Feasibility of coding different engine/transmission (VO?)

BIMMERPOST
     Featured on BIMMERPOST.com
Is it feasible to code say a N55 to a N20 car or vice versa. Going one step farther would is be possible to make the car expect a B series ecu? I know that the modules may not be happy but is it possible to at least force that in the VO or is my whole concept flawed?

From an academic standpoint I am wondering what is the chance a seamless engine swap could be accomplished.

Bonus: Not on topic here but does anyone know if B series and N series mounting points are the same for engines?

So I did some more digging and I think the answer to swapping a N20 to a N55 is it is possible and all you have to change is your cars "type code" or "typeschlussel" as well as add the ecu in and delete the old one?

I guess the bigger question is can we upgrade to the new ECUs used to run the B58 and B48? It seems like the cars were still similar enough that it should all work together but I'm unsure. Anyone who might have the knowledge for these difficult questions?

Why do you think that you can make a N55 to an N20 by coding?
This is a completely different engine with other components.
And also you can not just install the ecus of the B58 or B48. That does not work.

I think he would actually be changing the engine aswell, not just try and code a 35i in a 20i or something lol

Correct. The question is more of can an ecu be changed without upsetting the rest of the computers in the car and so that if you were to connect with ISTA it didn't get unhappy.
