Anywhere around the stock one would be just fine...I would not put it behind a good working cat though..

put it in the secondard o2 spot.. you dont need the back o2 sensor anyway.

Only if he had a test pipe would this be fine.

I am not sure which wideband you have, but there are many that have a narrow band output from the controller. This actually splices into the original stock O2 sensor wiring going to the ecu. You would only need to run one sensor(wideband) in this case. Almost plug and play.

i have a cat i live in ca... i either will put the bung on my hrc dp up top or right after my 1st o2 sensor..

You should keep the O2 about 12"s away from the turbo itself. This is so the O2 will be garranteed not to get too hot. If it gets to hot it wont read properly. I would mount your O2 just after the curve of your downpipe. What wideband are you using? I am using a Bosch wideband. Good luck.

What controller with the Bosch LSU4 sensor?

How do you use it? (display only or input into a standalone)

This is an area we have not discussed. There are many more choices now available and some are accurate as hell.
