Review: Works great for on a budget! - Been working spot on for over a year no issues. Only think I can say compared to the authentic AEM gauge is that this one responds just a little slower but is still accurate.
Review: Visible Real time combustion results - I read as many good things as bad things about this Air/Fuel gauge. I even bought extra Bosh sensors (still in the box today) expecting quick failure of the UEGO supplied sensor. However, all functions and devices shipped with and built into this gauge "kit" are working flawlessly for the past week. This is not a long time track record, but my fingers are crossed for continued performance. In the past, I was not able to get a good tune-up on my Edelbrock model 1406 carb, but with this gauge I can see in real time the results of new jets and metering rods. BAM! Spot-ON! Zippity-Do-Dah! Noticeable improvement in acceleration, emissions and probably economy. I'm still working on lowering the richness from the secondaries under wide-open-throttle (W.O.T.) only because I don't yet have the smaller jets, but this gauge will tell me when I've got it right! My ideal gauge numbers are 14.7 while cruising and 12-13 W.O.T. NOTE: I am using the factory default measurement setting and have not yet used the other 2 measurement settings including (LAMBDA).

## Questions & Answers

**Q: Is this gauge waterproof?**
A: no

**Q: What is the wiring diagram for the 6 wire 02 sensor that is included? I want to hook up to a 4 wire bosch 02 sensor instead.**
A: It has instructions for how to wire the gauge into the wires from the O2 plug. But the plugs are standardized, so you shouldn’t need to rewire it. Just plug it in.

**Q: Is this kit more reliable than the AEM ones?**
A: I wouldn't say it's more reliable but it's saying it's close I've been using mine for about a year with no issues

**Q: Anybody got a color scheme for the wires? I've lost the instructions.**
A: its just red key on hot black ground the other two are for another gauded of like for your cars ecu those are white and blue you don't need them jusy red and black  for stand alone also you can look in the AEM website it's a copy of that

### ⭐ Didn’t work
*by P***. on March 8, 2025*

Hooked up the gauge for the first time today. Had sensor hooked up before adding power and ground. Gauge came alive at 14.7 and then climbed to full lean. Which seems correct since the engine wasn’t running. I started the engine and nothing. I tried more throttle and not a blip of change. I verified good power and ground. If the company can reach out to me about warranty for the sensor atleast, I’d appreciate it before I return the whole setup. Or if they have any in-depth T/S. I was hopeful and and thought I’d get lucky with a good setup, but it seems the reviews are accurate and the sensor is junk
