Probably the wrong engine computer. Did the person that told you this have experience with swapping in incorrect engines or were they BSing you?

I believe the advice to be honest. They had nothing to gain from it and they are serious Subaru enthusiasts!

Have them show you how it works. I would never try to mix and match engines and ECU's.
