I was at Autozone getting oil the other day, and I was just killing time looking through the isles, when I saw an A/F ratio gauge by Sunpro I believe. I have been needing to buy an AEM wideband, but this 50 dollar gauge got me curious..normally I'm not the one to go cheap when it comes to parts, but I could not think of why this gauge wouldn't work just as well as an AEM...
I know the AEM comes with a new O2 sensor and wiring for the gauge to plug into the O2 wiring, so I asked if I could open the one at Autozone to see how it hooks up. Its essentially the same as an AEM, its got 4 wires that splice into the O2 wiring. The only downside I can see is the Autozone gauge doesnt give an exact number readout of your A/F ratio, it just has a scale marked with "Lean", "Ideal", and "Rich". Would this gauge do me any good? Or at least till I can afford an AEM?
