It depends what engines you are swapping ?
I think you can get away with just a chip change if you are swapping from a 2.0l M20 to a 2.5l ?
Thats assuming your using the same version/age of Motronic ECU.

Same one will be fine mate!
Bear in mind it will lose it's memory after being unplugged for a while when you're changing the engine so might run a bid lumpy for a while. Just take for a nice drive so it can relearn then settings and you'll be fine.
