Where do I need my o2 sensors on my setup? It's a short header to crossover to a log to a single turbo... I have a third o2 for my wideband in my down pipe... do I run both the upstreams in the crossover or ????
Thank you!

Here's a pic of my crossover. You can see where the O2 bungs are.

my only question is on my setup if i put both in the crossover, theyll mainly be reading from the one bank right?

because theyd be before the log manifold?
has anyone put one in the crossover and one in the downpipe? or would that screw things up

my last set up i had both on the downpipe, although i was wondering what difference it would make to have one on each manifold..?

You had 2 o2 sensors in your DP and none on your manifolds.....what?

Wrong. I was able to log both 02's...Bank 1 and Bank 2 separately. I know, because one O2 was failing and causing a rich condition on Bank 2. Keep in mind, that the 02 is getting exhaust...down flow, from it's manifold.

this is my hot side setup... see what i mean how its hard to put the second o2 after then second bank... theyd both be on the crossover... how should i locate the second one?

Ya that looks like a pain in the ***. You might be able to put an o2 in just one of the cylinders. I dont know how hot it would get though.
