P/N: AEM-WBGK

The wideband UEGO sensor controller accurately monitors Air/Fuel ratios (AFR) during the tuning process to prevent a lean fuel mixture, which could lead to engine damage. AEM has combined its single-channel wideband UEGO controller and gauge display into one unit, uniting unsurpassed AFR accuracy and control with an easy-to-read interface. This Gauge-Type Wideband UEGO Controller features a digital LED display and sweeping LED “needle” that changes colors as AFR changes from rich to lean. The unit’s 52mm (2-1/16”) gauge housing fits in most gauge pods and can be remotely mounted virtually anywhere.

• Ideal AFR monitoring tool for EFI and carbureted applications, and engine dynamometers

• Does not oscillate AFR reading like narrow band sensors

• No laptop required for monitoring!

• Bosch LSU4.9 sensor included

• Accurate to 0.1 AFR

• Reads in AFR or Lambda via a switch in back of gauge housing

• 24 Color-coded LED display lights provide immediate reference to engine’s air/fuel ratio (AFR) or Lambda ratio

• Integrated three-digit display reveals AFR or Lambda in real time

• User-programmable 0-5v analog output included for use with data loggers and virtually any engine management system

• Serial data stream included for output of AFR (RS 232)

PLEASE NOTE: For our AEM-30-4110+ Wideband Kit, we supply a legitimate Bosch LSU4.9 O2 sensor instead of the generic one AEM sends with the Kit. The 30-0300 will be supplied with the normally supplied AEM sensor which has no warranty. The main differences with these 2 kits is 1. The gauge depth is smaller with the 0300 kit vs the 4110; and 2. The analog output calibration is different between these 2 products. See instructions for specific values.
