Nope it's a totally different box.

Are you not able to import them from the US? They're available readily on eBay for like $90.

However there are many other GM Gen3 ECMs that can be substituted after reprogramming with TIS + tech2. I found a web page at some point that explained the compatibility (I think some Gen3 had electronic throttle, you need a manual throttle version).
