AEM Digital Wideband UEGO Gauge without Sensor

AEM's part number 30-4110NS Wideband UEGO air/fuel ratio Controller Gauge is sold without a wideband sensor. This allows users to source a Bosch 4.9LSU sensor separately to potentially save money.

AEM’s legendary Digital Wideband O2 AFR UEGO Gauge is a wideband UEGO air/fuel ratio controller (AFR) and gauge in one. It unites accuracy, speed and control with an easy to read, digital LED display and sweeping LED “needle” that changes colors as AFR changes from rich to lean.

AEM tested many sensors with the 30-4110NS, including popular inexpensive knockoff sensors, and determined that only the following sensors will deliver reliable performance:

Using the above sensors ensures that the factory sensor calibration is accurate and that the controller performs optimally. The use of any non-approved sensor may affect the controller’s operation, and will void the warranty of the 30-4110NS.

WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER?
AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced “You-Way-Go”) Controllers are powerful, cost effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of their engine.

WHY USE A WIDEBAND AIR/FUEL CONTROLLER?
Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned.

Elmo -in-a- Box !
Purchased as a gift for my grand daughter who happens to love Elmo. Cute toy with a little red Elmo who pops up and makes you jump if you’re not expecting it. It’s still working since December so that’s a good sign !

Cute but could be sturdier
For the price I wish it was a little better constructed. Elmo’s arm gets caught every time it shuts which makes it difficult for a toddler to do it alone. The lid is thin and can be bent easily. The music is very soft. The colors and presentation are very fun but it’s a little difficult for an 18 month old to play with on her own.

Love the idea, mine was defective.
Absolutely loved this item and the idea of it, but mine was defective when it came in. Elmo would not fully pop out when it was supposed to and had to be pryed out. Tried multiple times before deciding to return. A family member ordered one as well and theirs was perfect!
