uego: O2 housing or test pipe?

[bmadd2402]

Which is a better position for the uego wideband sensor?

Both should read AFR's correctly if that is what you are concerned about. If so, it really ends up on how much delay to the sensor you want. Further upstream will obviously register faster since it gets to read the exhaust sooner in the exhaust system. When you really think about it though, the delay is probably about half a second at most from the back of the turbo to the tip of the exhaust. In other words, you wouldn't get any noticable delay a few feet down stream on the test pipe by human standards. A benefit of having upstream is that you'll have less possible exhaust leak locations to throw the sensor off (makes it read lean). The down side of being upstream is that the closer you get to the head, the hotter the exhaust. The hotter, the lower the life of the sensor. I don't know if that was your exact question, but I hope it is answered somewhere in here.

Too hot at the o2 housing. Definitely put it in the test pipe or you'll be replacing the sensors often.

read the instructions. it will tell you how far down you need to place it after the turbo. where it goes is very important.

12-16 inches away from the turbo is general rule of thumb. Not to close to burn the sensor up, but not to far away to get an improper mixture reading.

+1 too close kills the sensor. give it at least a good 1 to 2 ft away from the turbo exit. i've seen shops put the sensor in the tailpipe (with a metal tube so it doesn't read fresh air) cuz not all cars have an accessible o2 bung. i wouldn't be too worried about the delay as long as you don't have any leaks

I've put about 6k miles on my sensor, and it is about 6 inches from the turbine blade lol. It is the sensor I first got with my LM-1 four years ago. I guess I got one that is way beyond quality control heh. I was expecting 500whp to weld the thing to my down pipe but didn't, so I ended up leaving it there.

Uego is actually 36" away mounted on a believe 0- to 10 degree angle at the pipes horizontal. AEM unit comes with all the installation directions.

I threw a bung at the end of my downpipe
