We proudly offer our WEGO™ Dual Channel Air/Fuel Ratio Display Systems with built-in data logging. These kits include the WEGO™ unit, Two (2) Bosch® LSU4.2 5-wire wide-band oxygen sensors, Two (2) 18x1.5mm weld-bung nuts for mounting sensors on exhaust pipes.

WEGO™ units are versatile tuning aid for all carbureted and fuel injected engines displays air/fuel ratio (AFR) and logs over 2 hours data including AFR, engine RPM, and a spare 0-5V analog input for sensors such as throttle position or manifold pressure.

Our WEGO™ units can be used for on-road or dyno testing and are suitable for all automotive, motorcycle, and other small engine applications.

All WEGO™ systems are highly accurate with less than ±0.10 AFR error over 10.3 - 19.5 AFR range (±0.007 Lambda error over 0.70 - 1.33 Lambda range) and feature a ‘Easy Free-Air’ calibration procedure corrects for sensor aging effects.

WEGO™ systems also include a 0-5V analog AFR output for interface to dyno instrumentation along with an ultra-bright daylight readable blue LED display with automatic dimming under low light conditions.

WEGO™ units feature a wide supply voltage range from 11-16V allows operation from battery on small engines and race vehicles without an alternator. Current drain is approximately 1 Amp per channel and includes a built-in USB interface.

Compact size: WEGO™ III is 4”L x 2”W x 0.5”H, single channel WEGO™ IV is 3.3”L x 2.1”W x 0.9”H

For tough and extreme environments, the WEGO III™ is fully encapsulated with a water-proof LED display.
