Introduction
The Fuel-Air Ratio Monitor
The ECM Fuel-Air Ratio Monitor (F/A Monitor) was designed for the professional
calibration of fuel-injection or carburetor systems. Using a wide-range UEGO (Universal
Exhaust Gas Oxygen) sensor, the F/A Monitor provides unmatched measurement range,
accuracy, and speed-of-response in a compact, lightweight package. Suitable for
dynamometer or in-vehicle applications, the F/A Monitor is an essential tool for any engine
development program.
F/A Monitor features:
• Measurement range of 0.055 to 0.125 F/A (gasoline

• Easy calibration in air
• 0 to 5 volt linearized output for use with data acquisition or engine control
systems
• SMB (Serial Measurement Bus) Interface on F/A1500
• Simulated O
