Std O2 Sensor

[ourr33toy]

Hi,

As the topic states im just curious if anyone on here knows what band the standard o2 sensor on series 2 r33 rb25 reads ive found the voltage is 0.1v to 1v variance but what is the actual band ive from 14-15 to 1 or is it wider than that ?

Weird question yes but i need the details for calibration reasons.

Cheers,

Being a Narrowband, and from what I've seen the range from about 0.5V to 4.5V will be an AFR of about 13.5:1 to 15.0:1

This isn't 100%. but its something

It reads hardly any "band"

It reads stoichiometric, and a tiny bit either side. As per all 3 wire O2 sensors.

From Wikipedia

An output voltage of 0.2 V (200 mV) DC represents a "lean mixture" of fuel and oxygen, where the amount of oxygen entering the cylinder is sufficient to fully oxidize the carbon monoxide (CO), produced in burning the air and fuel, into carbon dioxide (CO2). An output voltage of 0.8 V (800 mV) DC represents a "rich mixture"

I hope you're not trying to tune off that narrow band o2 like some V8 donkeys in the US..

I hope you aren't trying to do anything with it. Except what it's intended for!

Yuh, definitely not 0.5 to 4.5v. Max voltage on narrowband sensors is 1V, indicating fully rich (ie slightly more than stoich!).

Ahh yeah sorry. I was assuming it was a normal 5v sensor but now I do remember it only hitting about 1V When I had the power FC. Ignore my comments
