I was searching around the other day and discovered that the 2004.5+ 350z had wideband O2 sensor stock before the cats. Now I'm just wondering which ECU pin is used for reading that. I'm trying to hook up that to my A/F feature on the Apexi turbo timer. Thanks.

 

This doesn't answer your question, but I am not sure that will work for you. A traditional w/b uses 0 - 5V, the oem is only 0 - <2V. Might not give you meaningful readings on anything other than the ecu, unless you can callibrate for this sensor.

 

Interesting, but it's better than narrowband which only states open/close loop. Besides, I'd like to make use of every feature if I buy something so I feel like I get my "money's worth".

So.. anyone have pin # for this O2 sensor?

 

Anyone? Searching doesn't come up with much. I found ECU pin diagram and realized that there's like 5-6 O2 sensors. Which one am i suppose to connect to...? Thanks in advance.
