my question is where should i mount my wideband o2??? im gonna put a new bung in and i know it has to be before the cat but does it matter where on the pipe and all that???? and for those with a wideband where did u get the power for it at???

 

bump.....

 

would like to know this aswell

i put my sensor on the bottom part so it wouldnt hit the heatsheild, as for the power i hooked it up to the window switch's 30amps fuse on the driver's side, and grounded it to one bolt down there....if anybody needs more help pm me , i'll send u pics

 

Yea i got my bung welded towards the bottom of my downpipe, and I tapped power from the passenger fuse block, the sunroof 15amp fuse, and just like Sunburst I grounded mine to a bolt, just make sure you put the power on the left side of the fuse so it actually switches off lol, I accidentally put my power wire on the wrong side and it never went off!

 

I was told if turbo'd mount it atleast 36" from the turbo.
IDK about when sc'd.
I also believe you want the sensor mounted at a slight angle upwards.
I powered mine off a 10a circuit under the hood with a fusetap, don't
remember which one right now.

 

You can just get power from the stock boost gauge. Pretty sure that's where my mechanic hooked it up to.

 

18" from the head N/A, 36" if boost/nitrous/high EGT. After the turbo for sure. Anywhere in the DP will work. You should be at least on the side of the pipe or the top, never the bottom.

There's a fuse panel under the center stack. Pick your power source, there's a ton of them.

 

hooked it up to my rear 02 sensor bung and powered it to my heater fan. i have the rear 02 sensor code delete btw

 

Hey Joe why is it not recommended to plug the sensor upside down, i personally never experienced any problems with it on any of my cars and always got accurate readings, im pretty sure there's a logical explanation for it

 

It's not that it's upside down, it's that mositure/contamination in the pipe from condensation will blow out along the bottom of the pipe when the car is started. The element inside those sensors is basically a ceramic thing, and once it gets wet and dirty, it's garbage. As long as it's not straight on the bottom it should be fine, and honestly even if it was it might still last forever. Just a precaution. Not hard to mount it at a 45 degree angle instead of straight down usually.

Assuming you are catless, that's ok. Too far from the engine though really.

 

gotcha makes sense, appreciate the info dude

 

thanks for all the help... another dumb question im wantin to replace the stock boost gauge with a digital aem... doi have to run new wires or can i just use the stock ones???

 

Gonna need new wiring. Stock one taps into the factory PCM and MAP, the AEM one is gonna come with it's own sender.

It's not hard to install gauges...

 

I had my downstream deleted in my tune, then swaped out the downstream for my wideband. The wideband kit says it only needs to go before cat if im TC.

 

what about if your catless and you want to get rid of the CEL does it matter where its mounted at all or do i need that extra piece???? i forgot what it was called lol

 

The cat removes unburned fuel from the exhaust, so it will read leaner than it should. Your car though.

Best bet is to use one of those extension things or a j-pipe with the bung in it. You want it as far out of the stream as possible.
