Actually, I must be smoking crack tonight. The 1NZ and 2NZ are basically the same. I was thinking of the 1NR-FE, which is dual VVTI.

So, back to your original question - Your fuel maps would be a bit rich with a 1NZ ECM, but other than that it should be OK. Can you post a picture of the ECM connectors on your Vitz ECM?
