2 Air/Fuel Ratio Setup
Innovate Motorsports’ ‘Direct Digital’ wideband measurement principal allows you to
calibrate the sensor to compensate for sensor wear. This procedure takes no more than
a couple seconds and it will insure the most accurate readings throughout the oxygen
sensor’s life.
2.1 Sensor Calibration
The calibration procedure requires that the oxygen sensor be in free air, not in the
exhaust.
1. Connect the oxygen sensor to the provided sensor cable and then to the
appropriate port on the LM-2. Note: The dual channel LM-2 model allows you to
connect both oxygen sensors to the unit at the same time to do the calibration
simultaneously.
2. Connect the LM-2 to the cigarette power plug with the provided cigarette power
adapter.
3. The sensor(s) will start warming up. The LM-2
will display WXX, where XX is the percentage of
temperature reached. Notice the status bar
displaying a ‘W’.
4. Next is the calibration procedure. Press and hold the Mode button until the
Configuration Menu appears. Select ‘Calibrate Sensors’ and press the Enter
button.
5. Confirm by selecting ‘Start Sensor Calibration’ and press the Enter button.
6. The display will momentarily display ‘Cal’ and then it will switch to reading a
percentage of oxygen. If the oxygen content now differs from 20.9% by more
than 0.4%, repeat the calibration.
7. The LM-2 is calibrated and ready for use.
