Is it possible to use a 4 wire O2 sensor with a P2J ECU? Does anyone know the differences between the D15B(jdm) and the D15B(D15Z7)? Cause I was looking on craigslist and I found a D15B ECU, but they said it was a P07 OBD-I, I thought this was an OBD-II engine? Is there a difference? I'm asking this because of this thread: http://www.d-series.org/forums...34687

How difficult would it be to have this engine pass Emissions testing? Cause I was thinking that if the JDM ECU wouldn't pass emissions due to different OBD-II wiring hookup, I could swap the ECU with another ECU just for emissions testing every two years.

Is there a site that has all of the Civic ECUs listed, their difference and what not? Maybe an excel table?
