Interesting...
I think it's possible but takes time, LOTS of time.
To put it simply, here's the step:
1. Swap the Engine, might as well including the Tranny.
2. Swap the DME, EGS.
3. Swap the FEM.
4. Code all the "small" module to be same as the donor ECU and FEM vin
Are you really going to do this?
