over time will result if used with any of the following:
• Leaded gasoline and fuel additives containing lead

If the Air/Fuel Ratio Monitor responds sluggish, the oxygen
sensor is probably partially fouled and should be replaced.

Data Logger Output Range:
The Auto Meter Wideband Air / Fuel gauge has a signal output for supplying information to a Data Logger or engine management system. The signal
provided is a linear 0-4v output. See the BGD Range Setting Mode for information about how to define the air/fuel mixture values for low (0v) and high
(4v) ranges of the output in order to scale this linear signal output for best operation with your Data Logger or engine management.
