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 PSN-1.
Confirm that the top right-hand corner viewport displays “O2 E2.” This is
an error code, indicating that no sensor is detected. Leave unit powered
on for a minimum of 30 seconds.
2. Power
down
the PSN-1 and attach the oxygen sensor using the cable
provided. 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 PSN-1.
The PSN-1 will start warming up the sensor, this is indicated on top right-
hand corner viewport of the display by showing “O2 HTR.” After 30-60
seconds, the display will switch from “O2 HTR” and quickly flash “O2
CAL”, indicating that the sensor is being calibrated.
The calibration procedure has completed and the system is now ready
for use.
Important:
You can disconnect and reconnect the sensor and sensor
cable for installation without losing your calibration. However, if you
power up the PSN-1 without a sensor connected,
your calibration will
be reset
(see step #1 above).
2.6.2 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 Application, 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 Application
- Calibrate before first installation of new sensor
- Calibrate once per race weekend
