If I have time I am installing the UR high flow cat. I got full boost by 4000~4050 rpm so I am all good now

 

Hey I am trying to install my A/F ratio gauge. Do you guys know to which sensor I should tap it? Down pipe maybe? What’s the voltage on our O2 sensors? Thanks

 

About 1 foot from the 02 housing in the downpipe is the ideal placement spot. You will probably need to get a bung welded to the downpipe.

 

No my A/F gauge uses the stock sensor that's why I was asking what voltage it is???? any IDEA??

 

You would be better off going to a 99c store and asking if they had any christmas lights you can hang on your dash, since that will be about as useful as a narrowband 02 sensor.

 

I don't think it's going to be very helpful. Stock O2 sensor is only meaningful around stoichiometric AFR's (14.7:1) which is way too lean to be helpful.

 

Az3ar:
I can give you a link for a great deal on s Wideband Controller. I got mine for like $300 including all sensors wiring and control unit brand new with led read out. Let me know if you are interested.

 

yup so my wife will shoot me in the ***. No more car parts for few months, I just told her about the manifold and she said remember the bag I wanted ($800 bag) I am like yea I got to go honey. Why did I get married???

Hey guys any idea about guting out a high flow cat??? Any special tools??

 

so where should i connect my A/F ratio gauge too?

 

Long drill bit (spade) and a hammer along with some gloves

 

you can connect it to the ECU, but lie he said its going to be pointless, useless and inaccurate, because like evan said, 14.7, and if your trying to see if your running 11-12 AFR, then you need a wideband o2 not a narroband. I got a great deal on a wideband for 250

 

Well hook your A/F guage up to your secondary o2 sensor "the one in the cat". And why did you buy a high flow cat if you were gonna hollow it out? Should have just hollowed your stock one out? Anyway good luck on the a/f gauge.

 

haaaaaaaaaa . I am going to make some real holes tomorrow

 

Is it a PSX Devices? THats the one i got for around the same price. Works great and easy to read!
