Sensor Calibration - Innovate LC-2 User Manual


A 1" bung (provided in the kit) will best protect the sensor. When fully
threaded, the sensor's tip will sit flush with the exhaust pipe, this does
not adversely effect the readings.

The bung should always be welded before the Catalytic Converter.
Welding the bung after the catalytic converter will skew the readings
toward lean. The skew in readings will vary with engine load and the
efficiency of the catalytic converter.

Leaded fuel and two stroke applications will reduce the sensor's life.
There are many other factors that dictate the sensor's lifespan so it is
impossible to predict it's total longevity.

Exhaust leaks, camshaft overlap, and open (shorty) exhausts will cause
false lean readings at light engine loads. Typically, once the engine is
under load and the exhaust gas volume increases, you will see accurate
readings.

When installed in the exhaust, the oxygen sensor must be connected to
a powered, functional LC-2 (no error codes) whenever the engine is
running. An un-powered sensor will be damaged in a short period of time
when exposed to exhaust gas.

Do not pre-warm the sensor before starting the engine, simply start the
engine as normal. Allowing the sensor to pre-warm before starting the
engine will increase the possibility of damaging the sensor from shock-
cooling.

The maximum temperature of the sensor at the bung (the sensor
mounting location) should not exceed 500
temperatures are exceeded in your application you should install the
Innovate Motorsports HBX-1 heat sink bung extender. (p/n 3729.)
As the O2 sensor measures the oxygen content of the exhaust
gas to provide an accurate O2 reading, even a small pin-hole
leak in a poorly welded sensor bung will effect the accuracy
and performance of your O2 sensor. Remember, any deviation from
the instructions provided for proper sensor installation will lead to
inaccurate O2 readings.

Sensor Calibration

Once the LC-2 has been wired and a suitable location has been found for
both the controller and the sensor, it is time to perform the sensor calibration.
Innovate Motorsports' 'Direct Digital' wideband measurement technology
allows you to calibrate the sensor to compensate for sensor wear and
