No....no direct A/F ratio reading. But it does give you a O2 sensor millivolts signal which ****roughly***** equates to an A/F ratio.

It is as accurate as any of the ones you'll see in Summit Racing / Jeg's since these gauges also use a narrow band O2 sensor.

The ONLY way to get a true A/F ratio is to use a wide band setup which, unfortunately, is very expensive. There is a site which shows how to build an inexpensive, less accurate, wide band meter.

Good Luck,
