2) A/F Checker Released   We've been working on our A/F Checker for a while now, making several refinements before we released it.  Well, now its available.

A/F sensors (also called lambda or O2 sensors) are commonly used on our DataMite Loggers.  We often get questions about how we can tell if the sensor is still reading accurately.  Sometimes a problem could be something simple, like the wrong calibration has been chosen, or an electronic malfunction.  However, sometimes you just don't know.  The sensor seems to be reading "something", but how do you know if it is truly accurate.  That was the motivation for creating the A/F checker.

We know of no better way to check the accuracy of your A/F sensor and the entire calibration of your A/F system than with the checker.  By supplying shop air and propane from a backyard BBQ tank, you can produce a precise A/F mixture from 9 to 17:1 A/F.  Then check that your A/F measurement system reads the same as the checker.  If it does, your system is good.  If it does not, then you need to check where the problem lies.

If you work with different fuels, there's options for Methanol, Ethanol, E85, Lambda, and more.

The graph below shows how good and bad sensors compare to the calibrator over a wide range of A/Fs.  You will see that bad sensors produce readings which do change with A/F, which could fool you into thinking they were working accurately.  But you can see from the graph, the bad A/F sensors are way off, and if you used them for tuning your engine's would be getting a very incorrect A/F.
