As the title reads....

I am trying to gather more information on these recalibrated A/F Gauges. A guy I know has one for sale with the following discription.

"Calibrated A/F gauge (reads .800-.999) .. it only reads from .800-.999 and is very accurate. Your is probably very acurrate up to about.600 or .700.

On this one "stoich" would be about .900. It took me a few WOT runs to figure out exactly were it was, but once I figured it out it was dead on. And I never used a scanner after that (until I got the infamous 97 KR issue). "


How close to accurate would this be? I know its not a WB Meter, but if it gets me in the ballpark more times than not? That's a good thing.

I just wanted to get your all's thoughts on it before I said anything else.

Many thanks inadvance.
