Advanced Engine Management (also known as AEM) performance electronics are engineered to outperform the others. AEM is widely known for designing, manufacturing and assembling engine management systems, wideband air/fuel systems, water/methanol injection systems, performance gauges, data loggers, boost controllers, ignition components, fuel delivery components and adjustable cam gears.
AEM has just released the 30-4110NS Wideband UEGO air/fuel ratio Controller Gauge, which is sold without a wideband sensor. This is because the 30-4110NS allows users to source their own 4.9LSU sideband sensor. By allowing its users to source a Bosch 4.9LSU sensor separately, it potentially saves them money which is a plus. The AEM 30-4110NS gauge is priced at $130.

APPROVED SENSORS FOR USE WITH 30-4110NS
AEM tested many sensors with the 30-4110NS, including well-known inexpensive knockoff sensors, and determined that only the sensors listed below will deliver the most reliable performance. The use of any non-approved sensor may affect the controller’s operation, and will consequently void the warranty of the 30-4110NS.
Manufacturer | Part Number | Description |
AEM | 30-2004 | Bosch LSU4.9 (950mm) |
Bosch | 17025 | Bosch LSU4.9 (950mm) |
Walker | 250-25036 | Bosch LSU4.9 (950mm) |
Walker | 250-25075 | Bosch LSU4.9 (325mm) |
The new AEM 30-4110NS Wideband UEGO Controller Gauge features the same display range and calibrated scale on its 0-5V output (10-20 AFR), for data logging or closed-loop feedback control when used with a standalone ECU. A serial output (RS232) is also included for outputting AFR values for data logging and feedback control. See below for more information.
- Center LED Readout Displays Gasoline Values from 10 to 18:1 AFR
- Outer LED Ring Displays Gasoline values from 11 to 16.75:1 AFR
- 0-5V Output Gasoline values from 10 to 20:1 AFR
- 0-5V Output E85 values from 6.6 to 13.2:1 AFR
- 0-5V Output Ethanol values from 6.14 to 12.3:1 AFR
- 0-5V Output Methanol values from 4.4 to 8.8:1 AFR
- 0-5V Output Lambda values from .68 to 1.36
- Center LED Readout Displays Lambda values from .68 to 1.23
- Outer LED Ring Displays Lambda values from .75 to 1.14
AEM’s digital gauge-type wideband controllers have an LED display and sweeping LED “needle” that changes colors as AFR changes from rich to lean, a 52mm (2-1/16”) gauge housing that fits in most gauge pods. For more ease and convenience, these wideband controllers can be remotely mounted virtually anywhere. Uniting accuracy, control and speed with a very easy-to-read digital interface, the Wideband UEGO Controller Gauge is a must-have!
