webby: no, that wasn't me.
shouldn't the heater calibration be based on being "on the car"? it probably doesn't matter much. I dont think the manual says to remove the sensor and cooling fins prior to calibration does it?

If you connected a LED to the calibration button, you will at first see the LED blink slowly and
steadily. If it blinks for a fixed number of pulses, then switches off for 2 seconds and then repeats,
you have an error code. See Appendix for details.
Slow and steady blinking indicates that the sensor is warming up to its optimum operating
temperature. The warm-up period will last for about 30 seconds for a cold sensor, depending on
the sensor type used.
After the sensor is warmed up the meter automatically calibrates the sensor heater controller to
the particular sensor. During this 20-second period the LC-1 collects and calculates sensor
specific data required to quickly reach operating temperature in the future. After the first time use
the meter will use these values to regulate the sensor's temperature. During the heater calibration
the optional LED will blink fast and steady.
After the heater calibration is finished you should perform a free air calibration. The free air
calibration is accomplished by either pressing the push-button or connecting the black wire to
ground for three seconds and then releasing. During this procedure a connected LED will go off.
The LC-1 will now calibrate itself by using air as a reference gas with known oxygen content.
After the free air calibration is finished the LED should light up steady and continuously,
indicating correct operation of the LC-1.
4 Calibration
There are two types of calibration for the LC-1: free air calibration and sensor heater calibration.
Sensor heater calibration and first free air calibration is automatically performed the first time a
new sensor is used, while free air calibration should be executed frequently.
4.1 Free air calibration
To achieve maximum precision, the LC-1 and its sensor needs to be recalibrated frequently.
The sensor MUST be operated in free air for calibration.
Remove the oxygen sensor from the exhaust and expose it to free air (outside of the exhaust
pipe) for calibration purposes:
1. Connect the LC-1 to 12V from the vehicle and switch it on.
2. After the sensor has warmed up, either press the pushbutton or connect the calibration wire
to ground for three seconds and release.
3. After the calibration is complete, switch the LC-1 off and wait for 30 seconds before you start
the car.
If a LED indicator is connected to the calibration wire, it will be off during free air calibration.
4.2 Sensor heater calibration
If you change the sensor – either with a replacement sensor or a new type of sensor --, the
heater circuit of the LC-1 needs to be recalibrated as well. (See steps in chapter 3 'First Time
-9-
Use'). The heater calibration data in the LC-1 will be reset when the device is operated from 12V
without a sensor connected for at least 5 seconds. You can force a reset by doing this, and then
recalibrate by turning the unit off, reconnecting the sensor, and turning the unit on.
After the sensor is warmed up the meter automatically calibrates the sensor heater controller to
the particular sensor. During this 20-second period the LC-1 collects and calculates sensor-
specific data required to quickly reach operating temperature in the future.
Note: When using the Bosch Sensors the LC-1 may perform multiple calibration passes.
This is normal and need not cause concern. When it completes, the LC-1 also will perform
a free air calibration. Make sure the sensor is operating in free air for the heater and free
air calibration.
4.3 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 (tuned rich):
- Calibrate before installation of new sensor
- Calibrate new sensor again after 3 month of use
- Thereafter calibrate twice a year or every 10,000 miles, whichever comes first
Race car
- Calibrate before first installation of new sensor
- Calibrate once per race weekend
Dyno use
- Calibrate a new sensor
- Calibrate every 2-3 days, depending on usage

3. Switch the 12V supply off after 10 seconds.

Read it yet? or just the first line?

HEATER calibration. not free air.
