Edelbrock Air/Fuel Ratio Monitors are made up of an oxygen sensor and a calibrated electronic display, which indicate air to fuel ratios from approximately 12 to 15:1. The monitors should be used as a tuning tool which will guide fuel adjustment and jetting, and will improve ignition spark advance curves. They are very suitable for applications and conditions where frequent altitude and climate changes are encountered. The monitors come packaged with an oxygen sensor/bung, a wiring harness, and display unit.
