The WEGO IIID is a dual channel air/fuel ratio (AFR) metering system designed to be used with an existing data acquisition system. The system has two 0-5 volt analog AFR outputs. The compact size and wide supply voltage range also allow operation from small rechargeable batteries in a broad range of applications.

The system uses low cost Bosch LSU 4.2 5-wire wide-band oxygen sensors. By utilizing miniature surface mount electronics technology, digital signal processing techniques, and a switching power supply for the sensor heater, the WEGO IIID provides the same level of accuracy as lab systems costing thousands of dollars.

The WEGO IIID is for individual cylinder AFR monitoring on V8 race engines. Includes 4 dual channel WEGO IIID units and 8 Bosch LSU 4.2 wide-band oxygen sensors, 12 foot extension cables, and 18 x 1.5 mm weld nuts. Intended for connection to an existing data acquisition system.
