Can you use the bung on the UR (Ultimate Racing) test pipe for the WB O2 sensor and get an acurate reading, or will the built-in "check engine" light fix interfere with the readings.

 

I would think it would mess up the readings slightly. I just ran mine to the stock hole in the cat back.

 

as long as you are running a cat delete or test pipe you can use it in the catback but its recommended to use in the down pipe before the cat section... i have mine in the 12 oclock position on the DP slightly canted to the driver side.

 

Well I have my rear o2 in the catback bung with the sparkplug anti foulers because the built-in fix for the UR test pipe stopped working, thats why I wanted to put a WB O2 in the testpipe bung.

 

I thought the bung on the UR test pipe might act like one of these devices sold for WB02 sensors. Link Here



The Bosch LSU4.2 wide-band O2 sensor (shipped as part of the LM-1 kit) is rated to operate at an exhaust gas temperature of < 1300 degrees (F), and a sensor housing temperature of < 900 degrees (measured at the bung) for maximum accuracy and control. When either of these operating temperature ranges is exceeded, the sensor can no longer be accurately controlled. Further, operating at or over these temperatures for any length of time can significantly reduce the lifetime of the sensor. The LM-1 is designed to display an error message under these conditions (currently 08- Sensor Timing Error) rather than provide inaccurate readings. For some turbo vehicles, rotary engines, and other setups, this error message can be encountered with annoying frequency.

 

what do you mean work like ? you buy the wideband with sensor and cabling.. aem i know for sure comes with it, and so does the LM-1 if i remember right... you install the gauge or display run the sensor wires to it, mount the sensor in an O2 bung, you cant use your stock locations because you have to maintain those sensors in place.... just mount it in your dp right before the cat..

 

The short answer is no. I posted the same thread a few weeks back. https://www.evolutionm.net/forums/sh...d.php?t=203880

Have an exhaust shop weld on a bung. Word of advice: I had the shop chop off the elbow and weld on a bung on that exact spot but the placement was horrible. Depending on how you put on the testpipe, I ended up having the sensor wires rub the driveshaft or having the sensor hang way too low (4 o clock position).

Get underneath the car and mark with a sharpie where you want it and have a bung welded in.

 

i told you where to put it

 

This is where you want to mount your wideband O2 sensor: http://www.innovatemotorsports.com/f...read.php?t=442

I don't think they are asking about an 02 sim elbow. They are asking about using the bung on a testpipe! Why else would they put the bung there? The stock 2nd o2 sensor can still plug in the bung at the end of the catback right before it meets the test pipe. I don't see why you can't use the bung on the testpipe since it puts the sensor right in direct exhaust flow. Either way, thats's what I plan on doing when I install my AEM EUGO gauge.

 

There are a couple ways to do it if running a test pipe 24/7. I had a bung welded into the downpipe and I'm using that with the bosch wideband. The stock sensor is in the resonated test pipe, but since I'm getting the dreaded CEL as well as the placement of the sensor might rip it off someday when I lower the car below stock heights, I'm going to install an o2 sim, tie off the stock o2 sensor off into oblivion and cap off the test pipe.
