An O2 sensor is a vital part of a "closed loop" computer controlled fuel system. By itself, it's worthless, unless you can blink fast enough to read its output at least 10 times per second. I taught computer fuel systems for 20+ years in the public education system and a series of private seminars.

Ok, I’ll bite. What about the all in one A/F gauges like “artinva” links there. Do those read with some degree of accuracy?
