Hey guys,

Recently my o2 sensor has gone kaput. But in the mean time i've picked up a cheap piggyback, and I was thinking of using that to tune the car roughly to lean out some of the super rich fuel which comes out as a dark black cloud.

To do that I'd like to use an AFR gauge obviously using a wideband o2 sensor but because this is far beyond my area of knowledge, i've got all kinds of questions.

Question 1:
Is there a wideband sensor that will fit into the stock O2 sensor housing? If not I assume that the next best alternative would be to cut and weld a bung to house it?

Question 2:
I have a cheap AEM F/IC. It would like to see an O2 reading. Can one wideband O2 sensor send it's signal by splitting wires to both the FIC and the AFR gauge?

Question 3:
If i have a wideband o2 sensor, can the stock ecu get a modified signal off it? I've heard that some wideband O2 have two outputs?

Question 4:
Is bosch the best or should i get some kind of AEM wideband/AFR gauge? Any tips for where to buy? eBay has a bunch all in america from AEM which sound fine, except the america bit. I'd rather something local for shipping time reasons :-)

Thanks I love your help!

No
Not sure but I no they can be plugged into after market ecu
Fairly sure stock ecu only reads narrowband
Bosch is good but the aem does the job fine. Ebay is your friend.

Q3: Yes, The unit will have to have a narrow band simulated output (nbsim) which you can wire to the stock ECU. It will probably have a 0-5 volt output for data logging along with the AFR output display..

eg.

Most use bosch senors.. 4.9 is the newest and best bosch, NTK UEGO sensors are hella expansive as far as I know..

For local, you can support Australia right here

I have used it and it works well.. I also have the NGK AFX but it does not have nbsim..
