I have a ef with a b16a1 with a pwo computer i want the jdm itr header what do i do about the other 02 sensor? i want to keep the pwo computer . How do i wire it with it throwing any codes or making run crappy. Please tell me any options or if somebody has done this? And how bad does it run. thanks

 

Have someone weld in 2 O2 sensors at the factory B16 locations on your new header. You will have a better running car since this is the way it is supposed to be.

 

you can wire in a 4 wire O2 sensor, but at the moment I don't have any links for the schematics from what I found earlier was this:

Black (or white) -ground

Black (or white again)-12v switched (ignition- tap into one of the dizzy wires for this)

White (or black) -signal wire (C8 + C16)

Green (or gray) -sensor ground C12

or pretty much just look at your O2 sensor wire and the 2 wires that are the same color is the 12v igition and ground.

I was running the CTR headers on my wifes B16 and it worked perfectly fine.
