Best location for wb 02 sensor

[TSImuchforyou]

Where is the best place to put the bung or is their one? Thanks.

Im assuming you are not using any tuning like dsmlink.. to simulate the o2 signal if you install the widebands o2 sensor in the o2 housing original location. If you want to install to read A/f ratios externally for gauge.. . Welding bung 12-36in away from hotside of the turbo is usually recommended.Hope this link helps, pics were gone but should explain it

Thanks much. Where its located now I am either running super lean or its not reading right.

 

[Phantom DSM]

hmm hopefully its wired correctly and which "p" setting you are using, there can be some hiccups. Is it the uego ? Glad to hear you got a wideband, its a great point of direction to assist in your tuning, hopefully your not actually leaning out..

 

[TSImuchforyou]

Yeah its aem. I just bought the car I've had dsm for while been on this site for years haha but back to matter at hand. I know its wired right it never gets below 17afr car won't run with those afr I thought?

 

[Phantom DSM]

where is the bung welded at the moment ?

 

[TSImuchforyou]

Right after the flex pipe and its 3 inch turbo back

Well the location is not that bad, it should read something other than constant lean
There is a rotatory switch on the back of the gauge to calibrate and i found the pdf file to install if you would like to check the wiring with better diagram. Maybe previous owner installed wrong, it should be same model

Yeah its annoying as hell....worked good in my civic

 

[Phantom DSM]

Yea must be frustrating, it makes you paranoid on a/f ratioWTF
Dont be surprised if the bosch o2 sensor they supply with this kit goes bad, sometimes it happens. But as long as its positioned at a 10 degree angle, and has the correct signal, should work. Trace wire down to o2 harness wire Try the p0 setting, your pretty much using power and ground wires only at the moment.

 

[TSImuchforyou]

I have no check engine light so no misfire nor a lean code its just dumb haha

 

[Phantom DSM]

Well looks like the 02 sensor may be the culprit, check it out and let us know what happens

 

[TSImuchforyou]

I will and thanks for some of the insight.

If there are any exhaust leaks before the sensor it will also read lean. But if its staying a constant 17 I'd suspect the sensor as well. I've had my o2 4" upstream from the cat on my 3" and haven't had issues, its only been on a couple months though

 

[TSImuchforyou]

It moves from 17.5 to --- but never out of that range except when i start my car it starts at 14.8 then climbs to those numbers.

 

[Breezio69]

Hmmm, that's weird, my car does the exact opposite... while its warming up from a cold start I see 16.5-17.1, after about 30 seconds it slowly climbs to 14.8.

I always figured that would be normal? Running a little lean to warm it up? It also only does it on mornings 50* and below.

Are you tuning with anything? If I screw around and richen up my safc a few % just after start up the lean reading goes away sooner.

 

[TSImuchforyou]

Na it has a chip in it but I've thrown the stock chip in and it does the same thing.

i couldnt sleep so i went and checked my calibration it was on p04 now its on p00

 

[Phantom DSM]

I figured it was off on the p setting, i had to set mine on p0...Did it solve the issue bro?

 

[TSImuchforyou]

Idk... Broke a shift fork and then found out linkage is bent I'm so mad

 

[Phantom DSM]

dang, one problem to another..another daily driver beater to the rescue hopefully

 

[TSImuchforyou]

Yeah ill bring it back to par the linkage is out already and waiting for new one and hope hope to get trans out soon.

And I meant clutch fork not shift fork.
