Where to install air/fuel wideband O2 sensor
I am installing a wideband air/fuel gauge and I'm not sure where to put the O2 sensor. I have long tube headers that go into a Y pipe, then runs back. My question is should I put it behind one of the headers and if so which one. Im just wondering where other people put theirs. Thanks

When I first put mine in I had it right behind collector on passenger side and it didn't read right it always ran crazy rich readings and the wideband would just blank out. Wot reding we're correct but that's it. I moved to driver side behind collector and now it reads much more accurately or so it seems atleast . Wot is right on as well

Thanks guys, it was installed on the driver side not far behind the stock sensor on the inner side of the header at about 3 o'clock I will finish the install soon and I will post how it is reading.

I installed my sensor in the merge of the Y pipe, so it reads both sides of the motor. Any time you get the car tuned on a dyno they stick their wide band in the tail pipe... Reading both sides of the engine.

What has nothing to do with a y pipe setup or reading both sides ?

Unless u want to install 2 sensors, one for each side. Whats the point in monitoring just one side??? As for tuning u need to look at both sides separately, as for just a general eyeball on the motor, mine will be where the y merges.
Why would someone pick the left or right side? One over the other. Please explain your decision making process. Thanks

Cant individually tune each bank, so seeing both banks on the wideband doesn't make much difference.
You effectively tune "the engine", and in closed loop a correction is applied per bank, you don't have control over the correction, only of the base tables they are "correcting". ie. only one VE table and only one MAF table. Any variation bank to bank is handled by trims.
Picking one side over the other shouldn't make a difference. Both banks ideally would be seeing the same airflow etc, so they ideally should require the same fuel. It wont be 100% though, hence the trims. Using one bank as a reference is fine.

So what your saying here is putting wide band bung on each header is useless? Could you tune driver side where it looks good then swap to the passenger side to see what its showing and make adjustments that way and meet a median between both? Im new at this so just asking.

Say for example you have a clogged injector on the passenger side. When you go WOT, all the WB is reading is the driver side values which will look good...and you will never see the huge lean issue that is happening on the other side and you end up with a busted engine.
Not saying that you absolutely need dual widebands, but they are not useless to have on both for safety reasons.
