AEM WIDEBAND UEGO AFR GAUGE – DIGITAL

Description

AEM WIDEBAND UEGO AFR GAUGE – DIGITAL

The unit’s 52mm (2-1/16”) gauge housing fits 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 virtually any engine management system, such as the AEM EMS or FIC.

The Bosch 4.9 LSU sensor has a faster light off time and draws less current than the 4.2 LSU sensor used with AEM’s 30-4100 Wideband UEGO Controller Gauge. The 4.9 LSU sensors feature the same fuel compatibility as the 4.2 LSU and NEVER require free-air calibration when used with AEM’s 30-4110 Wideband UEGO AFR Gauge.

The new 30-4110 Wideband UEGO Controller Gauge has the same display range and includes the same calibrated scale on its 0-5v output (10-20 AFR), for data logging or closed-loop feedback control when used with a standalone ECU.

FAST, ACCURATE AIR/FUEL DATA
AEM’s World-famous Wideband O2 Air/Fuel UEGO (Universal Exhaust Gas Oxygen, “you-way-go”) Gauge is a must for anyone looking to maximize engine power and safety. When tuning an engine, accurate air/fuel ratio data is critical. Running rich can cause a loss in power, while running too lean may result in serious engine damage. The AEM Wideband O2 Air/Fuel UEGO Gauge features large LED numerals that can quickly alert the user to even a .1 change in air/fuel ratio, providing time to shut down an engine before damage occurs.

Each gauge comes with interchangeable black & silver bezels and black and white gauge faceplates for multiple color combinations.

EM’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.

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.

WHAT IS FREE-AIR CALIBRATION?
Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. This process involves removing the sensor from the bung while still connected to the controller device, then waving the sensor in the air so it can read atmospheric O2 levels. We use Bosch 4.9 LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated by Bosch and never require free air calibration!

CAN I CHANGE THE AEM UEGO SENSOR’S CONNECTOR?
No. There is a laser-etched, calibrated resistor in the sensor’s connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output.
