The three stage vtec is obd 2 with a 1 wire o2 sensor. It doesn't have a vtec oil pressure switch and but it has an extra vtec solenoid, I figured that all you would have to do is put a resistor in there. Japan has way more lax emissions standards. In addition, in japan the car powered a four door and supposedly got better fuel economy than our hx's. Several guys on on honda sights who put these in hatches for speed with ex tranny's swear they still get 50 mpg highway. The gearing in their trans' is definitely not as tall as ours. My dream was to mate the 3 stage ecu with vx tranny and hx head and the d13b. Everyone who uses those motors are almost always the racer types so I haven't found anything about when lean burn engages. The manual p2j ecu's show up on ebay every once in a while but they can be pricey.
