will car run different if i only run 1 o2 sensor (bridged at ecu)compared to running both (separately)? somebody told me this and i wasnt sure if it were true

 

do you have a chip in your Ecu?is it a pr3 ecu?and no your car will not run different cause for some dumb reason the b16's 2o2 sensors are placed to try and keeping all fuel intake the same so thay have them in ports 1-2 3-4 so if you bridge them the comeputer will never no cause the temps SHOULD be the same comeing for all 4 cambers..to make it short no and if your ecu is chipped then its even better

 

As I mentioned in your previous post those ecu's are real picky at closed loop partial throttle. The o2 sensors need to be in the correct place if you plan to run them. If not just chip the ecu.

 

the 1st o2 reads off 2 of the four & so does the second o2,Ive
heard its runs better w/ two hooked up.
1st o2 pin=c-16 the original oval plug
2nd o2=pin-8 green plug
this is for a pr3 setup........

 

well thats a good bring up,cause most after market headers,have the O2 end of downpipe from the ones i have seen waste alot more gas if it is located there i cut and rewelded a New O2 sensor hole in my manifold and it gives a semi big diff.and less gas wasting so it does make a diff where the O2 sensor is if your running one

 

well i tried running BOTH o2's and same thing....stuttering partial throttle...

 

could be like mine and hate o2's all together, ive tried hooking them up 3 diffrent times, and it runs better without them, so i leave them unplugged. occasionally it will catch that they arent there and pull a check engine light, but nothing serious.
