Features & Product Details

RallySport Direct carries a great selection of quality aftermarket performance gauges and gauge accessories brought to you by AEM Electronics. 

 

This is the AEM Electronics UEGO Wideband Controller 4.9LSU AFR Gauge. Wideband gauges are some of the most overlooked, yet imperative gauges you can have in your car. If your engine is highly modified, or if you plan on modifying your engine, then a wideband gauge is a must for your tuner, and a must for yourself to modify the overall running welfare of your engine.

The UEGO Wideband Controller 4.9LSU AFR Gauge provides extra insurance to your engine because if your AFR readings are outside of the tune or the strike zone, then it will let the driver know to stay off full-throttle conditions and investigate what is causing the changing in readings before any significant engine damage can occur.

    Great while its new, low life expectancy  2 years ago

    The sensor was great for the first year or so, worked exactly as it should. After about a year in there are several dead lights in the numbers and in the shroud. Now i have to replace the sensor as it reads constant lean, but the sensor has a limited life expectancy so that is to be expected. ~100 dollars a year to keep this gauge running with the Bosch 4.9LSU sensor. Mainly bummed out about the dead LEDs.

    Great gauge for the most part... 3 years ago

    I’ve bought two of these, one for each car. One has been on since June 2018 and has zero issues. The other I put on in September 2018, and one of the lines on the display no longer functions. Unfortunately I just missed the 1 year warranty cut off. Looks good for the price! I used a cheap plastic pod mount and a dremel to make some holes for the nuts on the back of the gage. Mounted the gage with some double sided tape above and to the right of the speedometer for easy viewing.

    Great display, a must have!  4 years ago

    This gauge is a must have for troubleshooting and tuning! Easy to read display and simple install with high quality harnesses and Bosch O2 sensor! I would definitely recommend getting a good aftermarket downpipe with the sensor bung installed, (I have the Cobb) even though the kit comes with a bung included. Don’t let a weakening fuel pump burn down your engine; get this gauge!

    This is a quality wideband and a must have for diagnostic troubleshooting and tuning. Easy install if you have a good aftermarket downpipe with the o2 sensor bung. (I have the Cobb DP) harnesses and connectors are high quality and the Bosch O2 sensor included is accurate and reliable. Don’t let a weakening fuel pump burn down your engine! Get this gauge! Thanks RSD for always getting parts to me in 2 days!

    QUESTIONS & ANSWERS

    • Q: Secondary O2 sensor  Kong2 years ago

      Would it matter if I replaced my secondary O2 sensor with this? Trying to get this for my BRZ.
      • 0 of 0 people found the following answer helpful

        A:  You would not want to replace your secondary O2 sensor with an Air/Fuel ratio gauge. The secondary O2 sensor is for monitoring the efficiency of the catalytic converter, not monitoring Air/Fuel ratio. You would want to get a bung welded in for the wideband sensor before any cats and after all the exhaust runners come together.

    • Q: Installation location  Mr Phil3 years ago

      I have an 02 sedan, and I know it says 18in away from turbo, but I have Aps TBE and the downpipe has an extra bung post turbo /pre-cat but only maybe 5-6 inches away from turbo, is this safe? Or can I mount it in place of rear o2 sensor as I already have a protune anyways? Also is the 10° angle thing imperative or just a suggestion? Thanks
      • 1 of 1 people found the following answer helpful

        A:  You would be fine with that placement, the distance is a recommendation but not ultra critical, just keep your factory O2 sensor in place and put this in the bung provided. And for the angle, again, just a suggestion. Also APS exhaust huh? Been awhile since I've heard that name. Those things were awesome :)

        A:  Thanks Rick. Yea I got the exhaust from a buddy of mine. He got in it on an auctioned car from out of state, I swooped in fast and bought it. Sounds amazing

    • Q: Cobb DP compatibility   MikeW1775 years ago

      Will this plug into the extra bung on the top of the Cobb DP? Also, any suggestions on getting through the firewall?
      • 0 of 0 people found the following answer helpful

        A:  Yes it would. There are a couple of install videos that I could reference. People have come up with some unique ways on hiding wires.

      Is it an analog or digital afr gauge? Or both?
      • 0 of 0 people found the following answer helpful

        A:  It will have a digital reading and then a multi color needle that sweeps around the numbers.

    • Q: Josh P  vincent446298 years ago

      My question wasn't about fitment. I'm just curious if it can catalog via serial cable out to log A/F to a laptop.
      • 1 of 1 people found the following answer helpful

        A:  This gauge can be used for A/F output to a serial cable/laptop, but the serial cable is not included.
