If you're going to rewire your harness, just go standalone. Megasquirt is a good option for the DIY'er.
in a wasted spark system, which the 1uz has, you can batch fire cylinders, hence a 4cyl ecu will work.
and its just an idea. there isnt much to wire up a p28, pretty simple if you ask me. ecu thats chipped and socketed is 100$ or so. then its MAX 250/300 for a dyno tune.
im just tallying up the cost and figure(minumum pricing) ecu: V1 aem- 750-800$(on a good day). wiring: panic wiring loom 350$. dyno session that includes initial basemap set up and tune-? id guess 7/800$. 2k later my car is tuned. add a map sensor, ait, etc and its more.
