were to weld my wideband bung?

[Oneslowgs-t]

i need to weld my bung for my wideband. should i weld it in the down pipe?
any specific angles or straight in?

It depends on the sensor and the manufacturers suggestions. I am personally running mine right after the flex section and at a 10* angle so that condensation can drain out of the O2 sensor.

I have heard that the best is after the o2 dump on the downpipe BEFORE the flex pipe area. Some get away with using the stock 02 housing area but i have heard it gets way to hot right there and ruins the life of the sensor and accuracy.

Key word there is heard.

AEM recommended 36" form turbo outlet. I thought that was a bit much so I went right after the flex section. When it comes to running the wideband in a spot other than the front O2, it's a matter of prefferance, opinion, and intended use.

I have installed mine in the 12 oclock position on my downpipe. You can see it in the engine bay behind the intake manifold if you look down behind the steering rack. I have had no problems whatsoever.

Wait, so is the front o2 sensor spot an okay place for it? Did i read the wrong information on dsmtuners??

Mine has been in the front o2 location for 2 years with no issue. I did make a copper heatsink for it though.

innovative recommends a copper heat sink but says its ok to run in the front o2 spot. i got good readings there. going to build a heatsink when i reinstall it though. itll last longer i think

Sweet, but what exactly is a copper heatsink?

Let me google that for you

I am so tempted to say "it's a heat-sink, made of copper," but I've used up my not-helpful/sarcasm points for the month (year?) already, so here: http://www.haltech.com/wp-content/uploads/2011/01/wideband_manual_1.0.pdf . Read page 8, in particular.

Edit: damn you, Bryan! One minute.

I know WHAT a heatsink is... but it could be ANYTHING. The Haltech link was nice thanks. Any pics of this on anyone's cars?

Grr. This took one minute to find: Wideband 02 bung - Club DSM Canada scroll down a bit

Note that the post in question there is from Scott McI, so it's not some schmuck with a piece of copper and a large drill-bit.

That stinks, I rather enjoy your sarcasm. Here you can barrow some if mine

My AEM uego wideband o2 sensor is approximately 10 inches down from the o2 housing outlet, in the vertical section just before the 90 degree bend. My sensor has died two times, each lasting about 3-4 months before giving messed up readings. I don't have a heat sink but I'll look into that. I wonder if my EGT is abnormally high to cause this? However when the sensor gave accurate readings the engine always ran rich at WOT, in the low 10 to 1 air fuel ratio plus black carbon in the exhaust tip, leading me to believe my egt is normal. I will try the heatsink and if that doesnt work then I'll relocate down the tube a bit.

This is good information to know when I do mine! I didn't read all the posts but I think from like 12 o'clock to 3 o'clock on the pipe so condensation or something doesn't get all over the wires or 02 sensor.
