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)

If you are using this wideband with an Adaptronic Modular ECU we have a connector cable adapter that will let you feed the signal through the ECU and WB’s serial connection, please select the “C” option for the added cable, or, you can find this in our Accessory section here.

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.
