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?

lol we all have our moments.

Running rich won't be bad as long as I can get rid of the check engine light. I ordered a bigger throttle body, hopefully it fits.

Next up are bigger injectors and an adjustable fuel pressure regulator.

I plan to dabble in a bit of forced induction soon. I'll see if I can get that pic for you in the morning.

Thanks
