Hey, I found a listing on craigslist for a GIAC ecu at an attractive price. My question is, can I put it in my tiptronic (automatic) s4 even though it came from a manual transmission s4?

Additional details: They are both from 2001, his is m-box, and I don't know what box mine is (how do I check?), mine is all stock too, if that matters.

Thank you very much in advance for any advice you can give!
