b16a2 swaped into a 92 civic si hatch, using a chipped p28 and a obd2 gsr wiring harness

I got a code 1: primary o2 sensory code after the swap, and now i put in a new o2 sensor, and reset my ecu and i'm getting the same problem!

any ideas??

at the passenger side shock tower i have 3/4 plugs on the obd2 gsr engine harness plugged in, the 4th plug doesn't seem to connect to anything.

PLEASE HELP!

 

has the o2 sensor been wired wrong or did you replace without rewiring?? if so, the 2 wires of the same color could be backwards

 

its wired correctly, when i swapped engines the o2 sensor that came with it should have been fine, but i replaced it anyways because there was a CEL code 1.
now that i've changed it out, there is still a CEL

i am pretty sure i am running in safe mode right now
bad mileage and dumping fuel at higher rpms

 

do you have the second O2 in your exhaust beccasue if you dont then that will throw a code also. and maybe you happend to get a bad "new" O2 maybe

Did u use a universal oxygen sensor as the new one? if u did, on my civic the WHite wire was the signal and the green was the ground. THe universal Denso sensor i had, has a white and blue wire. i put the 2 white wires together and the green and blue ones together, seemed to make sense. I kept getting the code 1 error and bad gas mileage and everything till i figured out those needed to be switched. Maybe this will help, maybe it wont but good luck on ur project

 

i bought a bosch one(#15733), but i guess it wont hurt to try again, i used the simple wiring diagram that i found on HT,


and wired it up that way

i read a post about some guy with the same bosch one as me and it had 2 white wires and a grey and a blue?

mine had 2 blacks, blue and white, and i wired it according to that digram any more suggestions?

I havn't seen the obd2 gsr engine harness used much on a bseries OBD2-&gt;1 swap before and i figured it'd give it a try, everything works cept this damn o2 sensor...

Also in reply to the guy above, I converted to OBD1, there is only one o2 sensor, what exhaust guys call 'upstream' or what i call Pre-cat (referring to primary o2)
