AEM 30-5130 Analog Wideband Air/Fuel Ratio Gauge with Black and White Face

Read lean upon installation. Contacted AEM resulting in lack of support for the product. do not recommend. Switched back to the digital gauge compromising the interior aesthetics of my build.

Works great with my AEM standalone for tuning and monitoring

Bought this to fine tune my carb and get my car to peak performance. Install was a breeze and wiring was simple and easy to solder. Was a little worried by the constant movement of the needle but was assured that's normal

Works as advertised, easy install, great for tuning carbs and finding the proper jet size.fast delivery with amazon, happy,happy,happy.good price too

Amazing how a company that specialize in precise measuring equipment can not measure their own items. This is not 52mm nor 2 1/16 housing. ( FYI 52mm = 2.04724 inches, 1/16 is 0.625 ) so even if you think the measurements were rounded that is not the case. The housing is actually shy of 2" and the bezel is 2 5/16. That is 1/4 inch bigger than the larger rounded up number. On tip of it the bezel is 1/2 thick. why would anyone want their gauge to stick 1/2" from their gauge pod? Oh well maybe some do. Any way that is not the point. The point is that if you are looking for an exact precise fit this is not going to work or it will stick out like a bump in your dash. I bought this hoping it will match the description which would have made it the closest match to my VDO actual 52mm gauges set up but it is way bigger in every direction. If a company can not measure their measuring product what do you expect from the product. Disappointing .

We actually bought five instruments and the data logger for our race car. Three had backlighting issues, the inner separator rings were deformed on two, and another two were missing the QC stickers. Considering we had nearly 2K into the system, we contacted AEM directly, sent in all the instruments, and waited. They suspected some might be returns. Have not confirmed that yet.When we received them back, one still had a lighting issue, two were still missing QC, and they were literally thrown in a box. The mounting studs on the backs of the instruments contacted the bezels on others and scratched them. Worst attention to packaging ever. Especially when you consider what your paying.

Defective product, still waiting for seller to respond. Absolutely is not an install issue, I've verified all connections and power to proper points under proper conditions.

I love this thing...it has really helped me to get my carburetor tuned

Nulla da eccepire, né riguardo la conformità né il prodotto.Non un problema che sia uno, sicuramente riacquisterei il prodotto al medesimo prezzo.Consigliato.

works as expected. Was able to lean out the carb and not worry about burning a valve

Works as expected. Takes no time to warm up. But look and feel is cheap... Not like a autometer gauge...
