The new 30-4110 Wideband UEGO Controller gauge is cosmetically identical to the original 30-4100 gauge.
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.
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 30-4100 gauge controller. The sensors are not interchangeable between the two gauge controllers in any way, including changing connectors on the gauges.
AEM’s digital gauge-type controllers feature a 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, and they can be remotely mounted virtually anywhere. AEM’s legendary Wideband UEGO ('you-way-go') Air/Fuel Ratio Controller Gauges unite accuracy, speed and control with an easy to read, digital interface. AEM created the first wideband controller and gauge combination in 2004.
