Blow-By Racing

 

The WEGO IV series are stand-alone units with built-in data logging intended for automotive under dash or dyno environments:

· Both WEGO IV units are identical except that the dual channel unit displays and logs two channels of air/fuel (AFR) data
· Complete AFR display system with built-in data logging. Includes WEGO IV unit shown above, Bosch LSU4.2 5-wire wide-band oxygen sensor (two for dual channel system), sensor wire harness, 18x1.5mm weld nut(s) for mounting sensor on exhaust pipe, and software on CDROM
· Versatile tuning aid for all carbureted and fuel injected engines displays 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
· 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
· 0-5V analog AFR output (two outputs for dual channel unit) for interface to dyno instrumentation
· Ultra-bright daylight readable blue LED display with automatic dimming under low light conditions
· Wide supply voltage range from 11-16V allows operation from battery on small engines or race vehicles without an alternator. Current draw is approx. 1 amp (2 amps for dual channel unit)
· Built-in USB interface
