If you want to know that your stock o2 sensor is generating the rich to lean voltages nescessary for the cars computer-fuel control, this gauge will display the rapidly changing fuel states with rapidly blinking indicator lights, which can drive the eyeballs batty during night driving.

The lights will not give a precise air/fuel mixture; but if they are swinging back and forth, an assumption can be that the average is around the stochiometric (14.7:1)air fuel mixture.

This is a pretty good starter air fuel raito gauge. It seems to be pretty acurate and very easy to install. well worth the price!

It works as described but I feel it would be better if the response rate was a little slower as that would make it easier to read.

I bought one of these for my grand prix,easy to put in but did not work.I called the sunpro helpline to firgure out what was wrong,they said it was a bad internal ground.So I sent it back and ask for anothor one.When I got it had the same problem, sent it back and got a refund this time.[By the way the problem ground makes the gauge read rich with car on or off nonstop]

Neat little gauge, Looks pretty good and install was easy. Instructions were easy to fallow.

I wouldn't rely on it. As a previous review stated it's mostly a light show I'm sure it's reasonably accurate but its readings are vague aka if your looking for something to give you some really good info... get a wideband.

Easy to install (87 Dodge Lancer), easy to read, a very nice entry-level A/F gauge.
