Just curious cause Im just running one and people say its slowing me down.

 

Stock uses two. If your only running one. you probley have code and your in limp mode. If you have them both wired up to one. Then your probley running real rich.

 

the shoped hooked both to one and now Im running hella rich how do I solve this problem.

 

have the shop weld in another O2 and O2 bung.

Yeah, and put them in factory locations. Ryan

 

someone told me of you are using the pr3 ecu that it wont run good you need to use the pw0

 

since both ecus read one cylinder pair,

if you tap both o2 wires to one sensor it will tell the ecu that cylinder pair 1 is running 50% richer than it should, and it will tell the the ecu that cylinder pair 2 is running 50% leander than it should.

then the pr3 ecu will try adjusting by dumping fuel in 2 injectors and leaning in the other 2 and you car will never run at optimum performance because the ecu is ******* retarded

 

ok so how do I find out which ecu I have? and does anybody have a picture of where my second o2 needs to go? cause my car runns like ***

 

You could also get your ECU chipped so that it will only look for one 02 sensor.

 

&lt; only running the primary but im also running a zydene

 

how do I doo that seahag

I am running both...

 

by b16 runs super strong, and I KNOW it is cause I wired my o2's perfect. Ryan

 

since the shop tryin to tell me it dont matter I told them I want it done they said ok, does anybody have any pictures of how the 2 o2 sensors are properly installed? I alreayd have one o2 on one of my primary down tubes welded in to my dc header, where does the other one need to go? and which order? currently both o2 wires are hooked up to one o2

 

probably have to weld in another bung where the other two cyl. meet. I don't know though. just a guess since each o2 sensor reads 2 cyl. shadowstylz, where did you get your swap done?

 

If I remember correctly, the 2nd o2 sensor should be directly across from the location of the one you have now.

 

damn so that means gotta take the header off and crossmember off again? and I go tmy swap done at schaffers auto care in woodbine, md they were highly recomended but now Im starting to wonder.....

 

Put the o2's in b16a factory locations. That means, if you have a 4-2-1 header design, put the bungs in the "2" pipes. Put a screwin, or weld/ fill up the bung in the collector, if there is one. Ryan

 

I'm running both. the pairs are sniffing 4-1 and 2-3. Make sure you put them on those pairs or else your exhaust pulses won't be being detected properly...
I used 1G JDM header, I ported it a bit, not much you can do as it is pretty efficient from the factory already. I used US ITR down pipe. It's not a bolt on, only 1 stud fits, the other 2 have to be drilled. WIth that downpipe, your stock Cat will bolt right in.
THe O2 plug you already have should be connected to the green plug O2 plug on the JDM 1G header.

HTH

 

definately run them both or get your comp chipped

 

Thanks for the info on chipping the ecu for one o2, I was not looking forward to welding 2 bungs into a Comptech race header.
