WEGO IV - Dual Display Wide-Band AFR Meter Systems

• WEGO IV Single/Dual channel Single/Dual Display systems are complete air/fuel ratio (AFR) display system with built-in data logging. Includes WEGO Dual Display unit, two Bosch LSU4.2 5-wire wide-band oxygen sensors, two 18x1 .5mm weld nuts, and software on CDROM.
•Displays Lambda or correct AFR values for any hydrocarbon fuel with a known stoichiometric ratio.
•Versatile tuning aid for all carbureted and fuel injected engines displays AFR and logs over 2 hours data including two channels of AFR, engine RPM, and a spare 0-5V analog input for sensors such as throttle position or manifold pressure.
•Input for optional customer supplied flex fuel sensor. A switch under the sensor 2 LED allows selection of normal AFR display or 0-100% ethanol display.
•Can be used for on-road or dyno testing.
•Suitable for automotive, motorcycle, and other small engine applications.
•Measurement range is 10.3 to 19.5 gasoline AFR or 0.70 to 1.33 Lambda.
•Highly accurate with less ±0.10 AFR or ±0.007 Lambda error over entire range.
•Easy free-air calibration procedure corrects for sensor aging effects.
•0-5V analog AFR outputs for interface to dyno instrumentation.
•Dual Display features a water-proof ultra bright daylight readable blue LED display with automatic dimming under low light conditions.
•Single channel WEGO IV is 3.3”L x 2.1”W x 0.9”H, and dual channel WEGO IV is 4.2”L x 3.1”W x 1.1”H.
•Wide supply voltage range from 11-16V allows operation from battery on small engines and race vehicles without an alternator. Current drain is under 2 amps.
•Built-in USB interface.
