O2 sensor and aftermarket wideband

[Pocket Rocket]

Ok I just installed my cork sport catted down pipe. I also have an autometer wideband Im wanting to use. Does the stock o2 sensor behind the turbo need to be in the downpipe or can I just plug my wideband in there and clear any lights I get with my AP?

[jracer]

The DP should have two-three bungs for 02 sensors .
You have to use your stock sensor and the stock second sensor .. Then add your wideband

And if you have a AP you can monitor your air/fuel with that .. So no real need for the wideband

Why do I need both stock o2 sensors connected? Cant I use the one o2 sensor thats down the pipe for the stock and the one up pipe for the wideband?

Your car uses it to calculate things. Like how to keep your motor in one piece

I drove it around the block and did a data log with my AP and after looking at the numbers from previous logs with the upstream o2 sensor in, they look pretty similar with the sensor out and my wideband in its place. What am I missing?

Are you going to question and argue everything or are you going shut up and listen? The wideband does not talk to your ECU, it talks to your AFR gauge. So your O2 sensor needs to be able to read exhaust gases to tell your ECU what to do!

You like the rest of the tools here roll up into a thread to spew some sarcastic remark and think your it makes you some kind of hero amongst your nut swinging buddies. Answering the question would be quicker although I doubt you know. Ive searched high and low and have found no info on this.

I worked on many cars before where the O2 sensor is disposable. Worst that happens is a check engine light. Im new to this car and looking for answers. If you dont have them, get the fuck outta my thread brah.

This is the best answer yet thank you. I know my wideband doesnt talk to the ecu. I just thought that the downstream o2 sensor would be sufficient for that info. Looks like im going to need a 3rd O2 bung on my downpipe before installing the wideband. Thank you.

it's cool. keep thinking your O2 is disposable. i'll point you in a direction though; lean/rich mixture. if you can't figure shit out with those 3 words, then stop touching your car.

[2012FailWheelDrive]

You need both, especially in a gen 2. Without either you will get wrong reading and/or shitty performance from your ecu not knowing whats going on.

Your reading comprehension is disappointing. I didnt say the O2 was disposable for this car. Some cars you can mod and removing the O2 is now big deal to how the motor runs. I was trying to find out if it was necessary and thanks to a couple of useful posts I found out it is. Its so much easier than wading through the endless sea of smart ass remarks anytime a question is asked in this forum.

Big thanks to the people that helped me. For the trollers in here, I hope you get in a terrible car accident that takes your life.

I understand you didn't say that, but your thinking was in that direction. Be pissy and uptight all you want. The information you wanted was readily available if you would have exerted just the smallest amount of effort. Instead, you wanted to be spoon fed. Kudo's to you for being lazy. Thanks for wishing death upon me. You seem like a keeper here.

Please find me a link to this info cause I couldnt find it. I searched for hours because I knew god forbid you ask a question on this board or you will catch hell. And ya, you seemed like a douche so death is the least I could wish upon you. Maybe you treat people a little better and theyll do the same to you. Hopefully youve learned a little lesson through all this. Cheers fat boy!

What about you do some reading noob before you start making stupid post or you want us to do your HOMEWORK for you.here is bone and you welcome.

fat boy? curious where you derived this from. i could give a fuck what you think of me or what you want to happen to me. bottom line is that you failed at searching and wanted your hand held.

edit: searching doesn't only pertain to this website. while a shit ton of information is located here, not every piece of information is located here.

And yet you still cant prove that an actual link to this exists LFMAO. Ive been apart of a few car clubs but this one is by far the worst. Congrats on representing your community as a bunch of cock gobblers.

not gonna do your searching for you. carry on.

One before the catalyst and one after, knowing that the catalyst is odb2 spec 90% of the unspent fuel should be consumed by the catalyst, given that fuel is adjusted until the catalyst is operating correctly, taking either O2 from the method used to check and expecting things to be ok is a little silly on a NA car, on a turbo it is foolish, some wideband gauges have a simulated O2 output so that you can do what you want and have some hope of having your car run normal (AEM for example).


Search more, type less and check the attitude at the door, rule one here is to search first, you broke the rule and the 'cock gobblers' are being polite, if you've found a better behaved and *more* knowledgable club, go there, but I doubt both are true.

you sir fail at reading comprehension. look at a prior post I made. there's important information regarding searching. Carry on.

[GODspeed7]

I'm usually the shark wrangler. I was nice to you and gave you an answer. Don't make me hate you. This car is not like other cars. You can't just bolt on parts and take off parts and expect to HAZ TEH FASTS!

Cock gobblers? Why yes.


BTW these cars come with wideband O2 sensors as primary O2 sensors, so there's no real need to add one. Some people do so they can monitor AFR with a gauge; it's easier to read. But it's not necessary if you have an Accessport.

[hamfisted]

Pre-cat/upstream O2 sensors are used by the ECU to adjust A/F. Post-cat/downstream sensors are used to check for cat functionality. The downstream sensor is the one that is usually safe to remove (& ignore CEL). This is how all OBD2 cars work.

Disconnecting the pre-cat/upstream sensor will usually cause the ECU to go into a "limp" mode and it's not a good idea to run it that way for long.
