I don't know what to tell you wolf. You hear all kinds of conjecture. This was my favorite:
"Doing sophisticated electronic stuff to a stovebolt engine is an exercise in futility, sort of like putting lipstick on a pig. Trying to measure exhaust O2 concentration with a multimeter- - - - -that's downright ludicrous since one of the diagnostic procedures scan tools monitor is how many times PER SECOND the sensor flip-flops across the median voltage, and if it slows down much, the sensor is deemed "lazy" and needs to be replaced. I hope the meter-reader has extraordinarily fast reading comprehension as the digital meter toggles through a bunch of gibberish numbers. Early automotive computer systems operated on a clock frequency (rate of information sampling) of 10 HZ. Newer ones upped the rate to 90 HZ. Good luck getting any useful info with a meter! LOL!"
3 voltages, everything above.. how about we change the rules a bit and just test and shoot some footage to back up what we do just to prove the critics like to talk.
Starfire, yes. I have all of the Jet sizes for the Roch B and plan on playing with that in the near future. This stuff takes time, so it may take awhile.
48, its a one wire sensor, so the wire in the center is multimeter positive and negative is sensor ground *engine ground is fine. No bias voltage, no goofiness, just take it off the sensor and read it. The proof it works is in the way the engine runs on both sides of stoic, and the plugs condition when you run it for awhile one way or the other.
Edit: 48, the science behind this has to do with molecules that create voltage based on the number of oxygen vs the number of gas. It can manufacture up to 1 volt. They figured out how to make 50% of its capacity mean Stoic or 14.7:1. The meter just reads what the sensor is producing on its own.
People like to make us think this is harder than it really is.
