WIDEBAND o2 SENSOR AIR/FUEL RATIO GAUGE

Regardless of what some people may claim, it is impossible to properly tune a fuel injection system on a modified engine without some means of exhaust gas analysis. Sniper offers the AF-5000 as a low cost alternative to expensive systems.
Conventional (narrow-band) exhaust gas oxygen sensors have been widely used in automotive applications since 1981. Conventional sensors have one to four wires and can only sense air/fuel ratio over a relatively narrow 14.5 to 15.0 range. They are intended to be used with 3-way catalytic converters that require operation near the stoichiometric point (14.7 air/fuel ratio).
The range of narrow-band sensors is inadequate for performance tuning. While originally developed for lab and specialized automotive applications, wide-band sensors are ideal for tuning. The 5-wire Bosch LSU 4.2 sensor used with the AF-5000 operates over a range of 10.3 to infinite air/fuel ratio.

The AF-5000 features built-in data logging. This data logging capability greatly facilitates engine tuning and diagnosis of driveability issues. The AF-5000 can store data up to 2 hours of operation. You can use our WEGO Log software to download and display this data on a chart recorder type screen.
Available data includes:
1) AFR (air/fuel ratio)
2) RPM
3) 0-5V analog.

Additional Sniper AFR features include:

· Complete air/fuel ratio metering system with built-in data logging. Includes WEGO II Wide-Band Exhaust Gas Oxygen Sensor Interface, Bosch LSU4.2 5-wire wide-band oxygen sensor, 18x1.5mm weld nut for mounting sensor on exhaust pipe, and software on CDROM

· Versatile tuning aid for all carbureted and fuel injected engines displays AFR (air/fuel ratio) 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.

· Red LCD display with backlight provides great readability in all conditions ranging from bright sunlight to total darkness.

· Compact size: 3.7"L x 1.7"W x 0.75"H.
