WBO2 Placement
On a dual cat shorty header system, where is the best place to put the WBO2? I would think that at the y where both banks merge, but can widebands be placed post cat?

Re: WBO2 Placement
I have mine on the y where both banks of cylinders merge. Its a heated sensor so it should be fine that far away from the engine. You want it before cat.

Re: WBO2 Placement
Here is another question. Should the NB and WB be on the same bank? If they are not, will I be fighting with one or the other?

Re: WBO2 Placement
I dont think it matters if both are on same bank as long as they are positioned right. I would stick wideband in one bank before cats. Real nice if you can get 2 bungs, one for each side and move it over to check other bank but both should be close. Unless you have serious issues with inj firing and air distribution, but you wont need a wideband to notice that

Re: WBO2 Placement
That is actually what I am going to do. I am going to be welding two bungs on on each bank and go between them when I tune to make sure that nothing weird is happening. I asked the question as I don't want to be tuning a lean area when the NB is reporting rich.
