You could always hook a voltmeter up and measure it yourself. You'd still get a semi accurate voltage reading and could base that reading on a theoretical A/F ratio.....0.5V being 14.7 and 0.95-1v being somewher around 12.0:1 with a fluctuation of .3 ~.7 closed loop. Or you could buy an actual LCD screen which would give you a digital voltage reading. If you look in the right places, you can buy one for less than $100.

Main problem is that our vaf is an old design. Almost every other automaker that uses the vaf system uses a 0-5v scale.

Here's a Toyota pdf showing a visual. Same difference:
