Some wideband set-ups do self calibration. Take a look at Innovate's. There's a quick special way to do it, but it only takes a minute and
involves plugging/unplugging a harness and a touch of a button.

They are very accurate.
If ever worried it isn't a replacement sensor is only anout $89 now.

Sensors will degrade over time, hence the need for calibration.

Yes, the innovative sensor has a very user friendly calibration option built into the unit.

I recalibrate my Wide Band sensors every time it is moved from one application to the next, and each time I blend a tank of CAM2 w/ 93 octane.

The Bosch WB sensor can be found on the internet for ~ $45.
