AEM Digital Wideband UEGO AFR Gauge

The World-famous AEM Wideband O2 air/fuel ratio UEGO gauge features a digital LED display and sweeping LED 'needle' that changes colors as AFR changes from rich to lean. A 52mm (2-1/16") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0-5v analog output for use with data loggers and almost any engine management system. Each gauge comes with black and silver bezels and black and white faceplates for multiple color combinations and a custom look (a black Lambda faceplate and black and white Air/Fuel Ratio faceplates).

The Bosch UEGO sensor gives the controller its speed and accuracy. The Bosch 4.9 LSU sensor used in the 30-4110 AEM Wideband UEGO AFR Controller Gauge has a faster light off time and draws less current than the 4.2 LSU sensor used with AEM’s discontinued 30-4100 Wideband UEGO Controller Gauge. The 4.9 LSU sensor features the same fuel compatibility as the 4.2 LSU and NEVER requires free-air calibration when used with AEM’s 30-4110 Wideband UEGO AFR Gauge. The 30-4110’s 4.9 LSU sensor uses a different connector than the connector used with the 4.2 LSU sensors included with the original, discontinued 30-4100 gauge controller. The sensors are not interchangeable between the two gauge controllers in any way, including changing connectors on the gauges.

Expedition rapide, soignee, avec une piece "bonus" non attendue dans le colis (ecrou de soudage sur pot). Appareil tres sensible et tres esthetique. Un must pour les preparateurs injections ou bricoleurs de carburateurs. Gain enorme de temps et de precision.

The top AFR for a top price (the best I could find in Europe and from the US the customs and the fdp are prohibitive). The kit is complete including the soldering ring to support the probe. It's perfect!

satisfied very good product
Product ordered on 16/12/2019 by Cedric L.

I put four stars because I could not yet test the product
Product ordered on 17/09/2019 by pierre m.

Kit received very quickly in relay point, perfect packaging, possibility of putting the mano in white gray or black, manufacturing quality at the top, I put that 4 star because the manual is in English, and the tip to solder on the line is steel, I would have preferred that this tip is stainless steel to solder on my stainless steel line, luckily I could make their piece identical in stainless steel at work, otherwise the cable is long enough to make your assembly, and despite the English, it is easy to connect the sensor (red wire +12v after contact, black wire ground, for the blue and white wire are two analog output to mount on an ecu, or other), once mounted I tested and yes indeed the value is nice, we see the evolution of the richness while driving

very good product
Product ordered on 24/04/2015 by Florian L.

Great product but not yet tested finish at the top but sensor wire and narrowband return are too short for rear central engine an extension is necessary...

Nice mano and very complete kit
Product ordered on 13/04/2014 by David P.

I went up without any problem with the help of one of your collaborator by phone!
Product ordered on 19/06/2013 by olivier p.

simple and effective product yes I would recommend this probe
Product ordered on 12/06/2020 by Charly G.

The mano is very Chinese. The probe seems to be of good quality (bosh). Not yet tested, here is my first opinion. Buy to run a jet ski on ethanol and confirm that the stochyometrics are not too poor.
