   I didnt know what to expect and although it does look like a bosch sensor. It still did the job. I’ve only used it once and only use it for carb tuning. I tried to tune it by listening and driving it but was not getting it. I can get close but not close enough untill I bought this and I love the way my fourwheeler runs now and I’m going to be using it again soon because I have a new clean air filter. Tried to use it without tuning but it’s getting way to much air. And judging by other reviews, I wont be surprised if I have to replace the sensor sooner than expected. Also hope the guage lasts. It started to flicker last time I used it but stopped after a couple minutes so it might be priced a little higher than it should be but still did the job though

   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.

   Installed on a 1996 Miata in the rear O2 sensor bung (after the catalyst). I get a P0140 code but it doesn’t affect the engine tuning.Pro Tip: clean the thread anti seize AEM puts on the wideband sensor. It leaked onto my sensor and caused it to read incorrectly. No anti seize!I used a switched 12v source and an inline 5 amp fuse. Be sure to use a dedicated source to ensure a clean power supply.I did a free air calibration before installing my replacement sensor. Seems to be working well!

   Put this on my 74 Chevy C10 it allowed me to adjust my idle fuel mixture and my jetting perfectly so my fuel mixture is spot on. The new carb I installed was a little rich out of the box and lean under power. With the jetting and fuel mixture now right my motor is making more power.
