I was wondering if you can bypass the need for a second oxygen sensor???
PR3 ecu, obd0
out of a JDM civic SIR
-or can you just run a wire from the first o2 sensor to the input for the second o2 sensor on the ecu duplicating the signal????
any imput would be appreciated,
thanks in advance.

no you have to run each wire respectively to the pins they go to. if you hook them both together it will give the ECU an incorrect reading and cause your car to run crappy........make sure the primary and secondary wires are pinned correctly on the ECU.

i bought my crx with a jdm b16 already swapped.. clean work except the o2 sensors were jumped into one input an inch from the ecu. to be honest it didnt run all that bad,, if i hadnt read the link on hondata i wouldnt think anything was wrong with the car so for you guys who didnt do your own swaps and have 2 oxygen sensors, check it out to be sure, im sure its easy to overlook if you havent done too much research. there is a crisper throttle response and better mileage to be gained. happy tuning
