AEM 30-0300 X-Series Wideband UEGO AFR Sensor Controller Gauge

I used this to tune my edelbrock avs2 that was surging at cruise. I wrote down the afr numbers while driving, looked at the edelbrock tuning chart and I needed a larger main jet and needle change. It's running like a dream now.

Un wideband muy compacto, de muy buena velocidad, y valores precisos.

good product has held up pretty good and pretty accurate

The media could not be loaded. There’s a good video on YouTube about Chinese fakes. The price on this is almost too good to be true, but since I like to gamble, I ordered one. I reviewed every single photo prior to buying this and could spot some that seemed fake according to the research video I found on YouTube.If you’d rather buy from an authorized dealer, like Summit Racing, you’ll spend maybe $30 more…

This is the best product on the market bang for buck. This sensor provides a wide range of measurements of rich and lean and provides provisions for a data logger to utilize the information off the sensor. Every component is of quality and is sure to last given proper installation and setup.

Its only letting me do 4 but this product is top of the line. Perfect reading. It doesnt break if you READ THE INSTRUCTIONS. Too many people put it in a way that the water cant escape then they say its garbage. No it aint

As promised, I'm updating this review based on the customer service experience. I installed this to replace a dying old 14point7 gauge and it was DOA. It just read "SEnS" when I powered it up, despite having good wiring continuity. I emailed AEM with a specific description of the issue and they had me call and arrange for a replacement, there was no hassle and the customer service people were friendly. When all was said and done, I put the new one in with the already-installed wiring and it works fine.I like the responsiveness of its output for tuning and the sweeping LED part of the display is useful for visualizing transients like acceleration enrichment when you don't have your laptop hooked up. The only negative about this unit is that the bezel is thick compared to most other wideband gauges, and based on the form factor of the actual gauge part the size of this part is pretty excessive. It's also gloss black, which doesn't match the satin/matte black of most interiors and gauge bezels, but I just had to remove the bezel and paint it to rectify this.Tip: don't go through all of the hassle of running the wires and stuff until you bench test it out of the box. That way you know it's functioning before spending a few hours fighting with grommets and taking interior parts out to run wires cleanly.
