The ECU is coded to the Pektron unit which is behind the heater panel (can't remember if it's called the Body Control Unit or the Body Systems Interface), but you're right - the old one won't work. And if you try it, you'll most likely get an error light on your dash that you can't get rid of, so don't be tempted!
Pete's right too - someone like Reidy's certainly should be able to take a flash reading of your existing ZR map and copy it to the ZS ECU.
