Yup, the Crown 1UZ's use 2 separate boxes. The auto trans box however likes the engine box to be present, therefore the easy way to run an aftermarket unit is to do the messy but common 'piggyback' appraoch - wire up the factory stuff fully, then run new wires to the injectors and coils, and connect these to the 'new' ECU. That way, you can set the fuel and timing, and the factory gear looks after everything else, like changing gears, idle speed, etc. Only thing is, and I'm not sure about this, you might need to leave the air flow meter in place as a load source for the trans ECU - this is quite possibly not true though, merely a guess on my part!  (seeing as people are always in such a hurry to ditch air flow meters when they fit an aftermarket ECU...)
