Wide Band AFR Monitor
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.
