So I ended up getting a 82 non turbo ecu from micro machine and the z seems to be running just as great before it broke. I didn't get to try any earlier ones and I don't know if its a federal or cali one.
well it is wired up a bit weird from what ive been told and i noticed the cali sticker and he said that it makes sense including the fact they did some werid emmison stuff in the 80's too. but doug at fairlady said that it shouldn't make a difference with ecu's as long as its a 83
