Is this a good mounting point for o2 wideband?
 

Hi guys
Is this a good mounting point for a o2 sensor for my wideband?
Cant seem to find a good place for it?
This is a BB exhaust single outlet
Thanks

Hard to tell what you're pointing at, but the conventional location is just aft of the turbo outlet, at the 10 o'clock position.

Is there anywhere to put it on the pipe instead of on the can?

Here's where I put mine on the old crispy critter.

You want it after the turbo and before the muffler.

Ideally, yes, to prevent possible lean reading due to ambient air if installed post-muffler as mine was. Some discussion and concern has been voiced about the sensor withstanding the higher exhaust temps when installed pre-muffler, so I eventually chose the safer route (for sensor longevity). For what it's worth, I never had any issues.

There is so little room post muffler and I am so tired of removing muffler / bumper etc
Has anyone have experience with those probes that go in the tail pipe?
Thanks

Too much latency IMO after the muffler. The gases stay "trapped" in the sound deadening areas since being diffused. I'd think it'd be hard to tune this way at part throttle. At full tilt, tuning shouldn't be that bad since the shear velocity of exhaust gases prevent stagnant accumulation.

Yep, at full tilt boogie not an issue due to the velocity of the exhaust. At idle, there's a chance that you'll read lean and end up adjusting richer than needed....but that's not bad vs. the alternative. I figured that most of us use AFR metering to be sure we're not too lean on the top of things, and this location works fine for that.

There's an issue is if you ever think you will use an EMS in the future. Then you want latency as low as possible.

Mark, there's just so much irony on you stating where to place the sensor to avoid "burning" it up. :D :eek: HEHE :)

Yeah, fer shur!!!! Though I have to admit that my sensor didn't survive the epic event. But still, life is good....
