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
o
C or 900
o
F. If these
temperatures are exceeded in your application you should install the
Innovate Motorsports HBX-1 heat sink bung extender. (p/n 3729.)
4 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
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.
