Wideband AFR Install Help

Ah missed that part. Do you have your Wideband mounted at the end of the Y pipe like previously recommended?

 

No.

I dont have any cats. Mine is installed on one cylinder on passenger side. I've tried to install it at the beginning of the Y pipe but had strange error codes and behavior from it so i moved it back and everything is right.

From my verifications, when installed too far downstream, it was too cold.

 

Wot is more like 10:1

 

Dammit, I'm really looking to get some information from someone who still has all of their cats and where they mounted their wideband at.

 

And I don't think my wideband has a heater, not sure though

 

Do you think that the spot where the Y pipe joints together would be too far down stream?

 

right where I have mine.... No issues...... I think @StillWill has same spot

 

Do you still have all of your cats?

 

I went from no cats, to shorties.

 

So you only have two out of your four cats right now?

 

correct

 

I guess I'll just weld it in at the joint in my y pipe and say f**k it. Even if my number is off a little bit it's still better than nothing

 

I was planning to do the same but after looking at the y-pipe and doing some searching around, I read someone saying the stock y-pipe is stainless. Can anyone say for sure?

 

That is a cool idea using a no weld band clamp. Where did you get it? Or was it a custom fab thing?

I am in process of installing a boost gauge and wideband. I have a 2012 and I am 100% stock with all cats. I just have a TRD exhaust. The boost gauge is reading 5psi at WOT. Is the stock blower suppose to put out 6psi? Not terribly concerned, just checking.

Also, I need to get my wideband installed and I will try at the y-pipe. I hope my cats wont throw it off to much. I will keep this thread updated when I get it installed. Not sure if I will do the no weld clamp or take it to my buddies garage with a welder.

 

5-6 psi is the norm

 

Ok. I was wondering. I was really only concerned because my auto meter gauge was suppose to come with a tab that holds the needle off zero for storing and shipping and you are suppose to remove the tab before use. My gauge didn't have that tab and I thought maybe it wasn't calibrated correctly.

 

what are the AFR readings that other boosted tacos are getting?

 

It all depends what you are running. Stock everything else will run rich, 10-11.

I removed the passenger side exhaust manifold myself as it is fairly easy to remove. Then paid a local shop to drill and weld the bung for about 30 bucks. I bought a new manifold gasket just to be on the safe side but my old one was actually in great shape.

at wide open throttle I am running 11.5. I have the TRD intake and a 2.85 pulley though so I get 7 PSI boost.
