atmospheric pressure variances. This procedure takes just a few moments
and it will ensure the most accurate readings throughout the oxygen sensor’s
life.
This procedure is required anytime a NEW oxygen sensor is
installed.
The calibration procedure requires that the oxygen sensor be in
free air
, this
means removed from the exhaust system completely.
1.
With the sensor disconnected, apply power to the LC-2. When power
is applied, the status light will light up green for 2 seconds while the
controller initializes. The status light will then turn red and flash a two
blink sequence indicating an Error 2 condition. This error state
indicates that no sensor is detected. Leave unit powered on for a
minimum of 30 seconds while it is flashing the Error 2.
2.
Power down the LC-2 and attach the oxygen sensor to the sensor
cable and the sensor cable to the LC-2. When making these
connections, make sure they are fully seated and locked. Again,
make sure that the sensor is in free air (not in the exhaust).
3.
Power up the LC-2. The status light will light up green for 2 seconds
while the system initializes. The status light will then start flashing
green twice a second indicating that the sensor is heating up to it’s
operating temperature. After 30-60 seconds, the status light will flash
green for a series of very quick flashes indicating the sensor
calibration is being performed. Lastly, the light will light up solid
green indicating that the unit is operational and ready to take read
O2 content in the exhaust gas.
You may disconnect the sensor from the sensor cable in order to
thread the sensor into the exhaust. To do this without losing your
calibration, make sure the unit remains powered off while the sensor is
disconnected. If you power up the LC-2 without a sensor connected,
your calibration will be lost and require the calibration to be repeated.
(see step #1 above).
4.1 Calibration
Schedule
Normally aspirated daily driver:
- Calibrate before installation of new sensor
- Calibrate new sensor again after 3 month of use
- Thereafter calibrate once a year or every 20,000 miles, whichever comes
first
Turbo car, daily driver (richer mixture):
- Calibrate before installation of new sensor
- Calibrate new sensor again after 3 month of use
