since I am most likely getting the PR3 ecu ith my B16a, will the stock header come with 2 openings for 2 O2 sensors.

Is there away i can use the pr3 ecu and get around having to use 2 O2 sensors, would the wiring be difficult?

thanks

 

obdii systems have 2 o2 sensors, one in the header the other in the cat.

I'm not really sure what your asking...but I hope that helps

 

DragII, first gen B16as sometimes have 2 O2s. They are one right next to the other on the manifold.

 

yeah just dont worry about it. it will work without 2.

 

alright
thanks

 

My stock header came with two openings.

 

really? why is this? that was before the OBD system was implicated right?
