Nice work! Have 1 question...
What is the wire colors for a Air/Fuel Sensor in 350Z?
Or how do you make A/F gauge work?
I've a digital one and have no clue to do it.
Please let me know.

thank you.

the basic a/f gauge has 3 wires, power, ground & signal wire. the signal wire gets tapped into the signal wire of the 02 sensor that sends voltage readings to the ECU. this can be determinced using a voltmeter. you can also use pin #16 at the ECU on the 03 model z's....

Thank you for your help. I've a 2004 model, I'm not sure it's the same or not. But thank you anyway.

What is the cheapest way to setup a AF gauge? What is AF wideband 02 sensor?

 

performance nissan has one that you mount in a bung in your exhaust system, but its $535. http://www.performancenissanparts.co...roducts_id=339

 

The cheaper a/f guages only read well at full throttle runs wich is fine with me. I've used them with several cars in the past so I have no problem reading them & tuning with them. The wideband set up is best by far but is costly. It uses a different more accurate 02 sensor & guages the a/f precisely for more perfect tuning. Both are easy to install but one is cheap & one is not. Like I said, I have years of experience using the older style a/f guages so I'm fine with it capabilities....... I do my initial tuning on a dyno for best results & use my a/f gauge as a monitor from there..........
