There has been some talk about this lately but there is soo much stuff in some of these threads its hard to distinguish what is right or wrong.
Ive talked to some people and have gotten different answers.
WHERE should I PUT my BUNG for the wideband o2????????
I was thinking 6" off the turbo(read it and got that info from some people aswell) would be fine but some threads(and some people I talked with) say stock place is best?
So what is it?
lets sort this out!

 

The stock location works good for me.

Interesting, it works well for me, but it doesnt work good for me.

 

what about 6" off the turbo?(im not doubting who i asked..just wondering what others think)
as ofnow 6" off the turbo(mounted horzontally) is looking like he best/easiest way to do so.

 

pretty much i put in about 4 inches from the turbo. I like it, and have no problems when dyno tuning. When street tuning I use stock portion only cause my bung at the top of the downpipe was placed sort of improperly so no way i can street drive it without scraping it off.

 

hrmm.. see its things like this.
Guys have been putting it 4-6" away and it was fine yet that expert guy posted it should be put down stream where temps are no higher than 750 deg/c.

 

I'd like to know. . .

Ditto

 

I'm running mine on a JRSC and I too have mines in the stock position. My tuner uses his in the stock position too when tuning (well actually not the actual stock location, but he weld another spot for his WB unit right where the stock one is).

Mine is setup like this before the sensor is on there:


Both are before the actual cat and right at the collector.

 

if i remember correctly somebody from techedge recommends putting the WB 18 in. from the turbo coz too much heat can affect the accuracy.

 

question would it be okay if you run hondata or uberteg software to just take out the stock o2 sensor all together when tuning and use the stock bung? dotn they run open loop at full throttle?

 

from the techedge website:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">The wideband sensor must be carefully placed in order to prevent damage to the sensor itself and to maximise accuracy. Also, if you use the sensor's output directly (via the simulated narrowband output) to drive your ECU then you should be doubly careful. Please follow all of these "rules" :

The sensor should always be placed on the engine side of a catalytic converter, unless you are testing the effectiveness of the convertor itself.
The gas temperature to the sensor should never exceed 850 degrees C (about 1560 degrees Fahrenheit).
The sensor should never be run without power to the WB unit (a hot sensor burns off carbon residues)
Always have the long axis of the sensor perpendicular to the gas flow (stops sensor clogging)
Position the sensor vertically or at most between 10 o'clock to the 2 o'clock position (this avoids cracking the internal ceramic structure should moisture condense internally)
We don't recommend using a short sections of exhaust pipe shoved up your tailpipe. A specially welded additional bung is the best mounting strategy.
</TD></TR></TABLE>

 

dyno's use widebands in the tailpipe, just like emissions testing, so I'm pretty sure that as long as the sensor gets a sample of the exhaust gas coming out the engine it doesen't matter where you stick the wideband.

 

You need to have it right on the downpipe 2-3" tops after the turbo, the reason you need it that close is to keep the sensor nice and hot that way you get an acurate reading..

i think mine is too close to the turbo, the poor sensor is blew

 

The FJO Instruction Book says to put it AT LEAST 18 inches away from the exhaust valves.

not much will change no matter where it is in the system,only two things you have to take into account is heat and freash air getting to it,so keep it away from the turbo and away from the end of the tailpipe where the freash air is,i actually put mine in the stock location after the oil pan and before th collector,then made a new bung for my stock 02 sensor about 6 inches away.

Keep in mind that the WO2 sensor has its own heater circuit. Therefore, stock location should be just fine.

 

i put mine in the stock place..(havent used it yet though)

 

If you look on the full-race downpipe, the Bung is welded in relatively close to the turbo
