Hey guys,

i was thinking of swapping a m52b28 that i have in storage and was supposed to be a parts engine to my m50 turbo to my e46 m52b20.
Do you know if i can just swap the engines and use the loom from the b20 engine and just get a b28 ecu or do i need the b28 ecu and loom alltogether?
Do you know what the tuning capabilities does the m52 ecu have? is it good for boost aswell?

Thanks
