2.5.2 Sensor

Calibration

Once the unit has been wired and a suitable location has been found for both
the gauge and the sensor. it is time to perform the sensor calibration.
Innovate Motorsports’ ‘Direct Digital’ wideband measurement principal allows
you to calibrate the sensor to compensate for sensor wear. 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 SCG-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 SCG-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 SCG-1.

The SCG-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 SCG-1 without a sensor connected, your calibration will
be reset
(see step #1 above).
