Hello!
I've recently purchased a bmw e36 325i
The problem is that original it was 320i
So the previous owner assembled the m50b25 engine with the same ecu (Siemens)and wiring loom from the original engine,(the ecu have an eBay "chip" that supposed to compansate the missing fuel)
Now,I've want to convert the loom that it fit with an 413 Bosch ecu and and suitable maf sensor,do I need to replace any other parts to make it work?
Thank for all
