wide band location

[luvmyz28]

hi all.
I've been searching for a while on here and hptuners site. i haven't found a definate answer on this. question is can I buy a wideband sensor and install it in the bung on my longtubes? or do i need to have a shop weld in a seperate bung for the wideband?

thanks in advance for your help.

I just drilled a hole in the Y pipe at an easy to get to location so I don't have to jack up the car and welded in a bung. The bungs in the headers are for you narrow band O2 sensors for the car's computer. I've seen adapters to use a wideband in place of a narrown band.

unless they've made advances in using the wideband sensors to adapt to narrow band I've seen people have trouble trying to do that. Your best bet is to have it welded into your Y just after the headers. I put mine about 6" downstream of the one in the header.

o.k.
thanks for clearing that up for me.

Also, I'd put it on the driver side. I know there shouldn't be a difference but with all the talk about #7 piston going lean/etc. (which I know can be a tuning issue too), it's just my preference.

So if I'm reading this right your stating to put the sensor on one side of the y-pipe after the headers. (does the side matter?) Why not put in in after the Y? ( pros-cons ) I'm planning on welding the bung in before I install the headers and Y. Trying to get my ducks in a row.

The further down stream you put the WB sensor, it tends to be slower, more "lazy" almost and does not get you as good of a reading if you were further up. I have mine right after the headers meet and make the Y-Pipe. Seems to be working so far.

i put mine in the rear o2 bung on the drivers side the ideal location is after the y pipe but if u have it dynoed just have the rear o2's tuned out then put it in there
