Easy sensor free-air calibration. All WEGO systems provide quick and easy at-a-glance verification and adjustment of the sensor free-air calibration. This allows the WEGO to maintain accuracy as the sensor ages and maximizes sensor life in racing applications where the sensor may be exposed to leaded fuels.

This is a single channel interface unit with 0-5V analog AFR output for automotive applications, includes Bosch LSU 4.2 oxygen sensor, and 18 x 1.5 mm weld nut.

Features:

• Single 0-5V analog AFR outputs for interface to dyno instrumentation or vehicle data acquisition systems.
• Versatile tuning aid for all carbureted and fuel injected engines.
• Can be used for on-road or dyno testing
• Suitable for automotive, motorcycle, and other small engine applications
• Highly accurate with less than ±0.10 AFR error over 10.3 - 19.5 AFR range
• Easy free-air calibration procedure corrects for sensor aging effects
• Wide supply voltage range from 11-18V allows operation from battery on small engines or race vehicles without an alternator. Current draw is approx. 1 amp
• Fully encapsulated (water-proof)
• Compact size: 4"L x 2"W x 0.5"H
