Aem 30-0334 Afro Sensor Controller (X-Series Wideband Ugo Gauge With Obie Connectivity) 2.0625 x 0.825 inches

Working as intended

Install is easy if you’re mechanically inclined, plenty of cable length. 10/10

I bought the 30-0334 for my 15 Silverado L83. I also run HPTuners. That being said the simplicity and ease of this OBD2 WB is like no other. Just plug and play really. Plus it’s the fastest WB I have used. Hardest part for me was getting the correct size Fuse splitter. No fault of AEM I wasn’t aware my truck has 2 different size mini fuses. The fact I didn’t have to run a bunch of wires and it has pass through OBD2 sold me. Only wish it were a little cheaper but hey.. the price you pay to be lazy! Lol

Very good gauge. Coming from an innovate gauge that gave me nothing but problems, this seems to be much better operation and quality. I received mine damaged but Amazon shipped a replacement the very next day. Don’t look at any other AFR gauge.

The media could not be loaded. When modifying your car to the point of needing a customer tune the AFR(air fuel ratio) is one of the most important readings you need. Not every car is equipped with wide band 02 sensors to do this correctly. In this day and age with email and remote tuning being so popular the piggy back OB2 connection is NICE. Plugging this unit into your obd2 and then plugging in your tuning/logging device allows the readings from this gauge to be captured just at is it was a factory PID. Works perfectly with HP tuners and DIablo. This is MUCH better than the old method that didnt work well.

I love this wideband. exceptional response time and calibration accuracy out of the box. You can free air calibrate it as it ages. Easily connects to my HP tuners by piggybacking on the OBD port and adding it as a can-bus device on your cars network. AEM has a video on how to set it up. This is a great option for folks running HP tuners standard since it doesn't require the analog inputs to log wideband data on newer vehicles. Also no need to worry about ground offset errors when using it in this manner. Its versatile though, you can also connect via older methods (0-5v analog and serial) if you have an older vehicle. It can display digital values in lambda but the analog scale around the perimeter of the gauge is only in AFR.I've marked it down 1 star because i feel its incomplete without the availability or inclusion of a lambda faceplate overlay (should be the default faceplate in this age of ethanol and blended fuels). AEM does sell a silver/white faceplate for it that they label as "AFR/LAMBDA" but they are in-fact labeled only in AFR... which of course is only a real value if you are running ethanol free gasoline. Its a small detail though because I really don't care about the scale around the perimeter, I only care about the digital number displayed in the center, and it reads correctly when set to lambda. Also it is missing the wires/pigtail from the plug that are required if you want output analog data... so you have to source the correct wire, pins and crimp tool if you want to output analog or serial data.
