Hi all,
I have a friend who's breaking his scooby blob eye wrx. He has a prodrive ecu installed and is selling it. I have the same car and mods etc, sports cat and decat with a h s back box, also a Kn panel filter. If I were to buy this and install the key chip and transponder would it just plug and play in my car?

 

Yes, dont even think you need to change the key chip and transponder. I think they are separate from the ecu.
