Do NOT install the Bung below the 3 o'clock or 9 o'clock position. Condensation
can form in the exhaust pipe and permanently damage the sensor. 6 o’clock is the
absolute worst position to mount the sensor.
Wide band oxygen sensors, like the one shipped with the LM-2, are designed to
work with unleaded gasoline. Use with leaded gasoline will significantly reduce the
lifespan of the sensor. The reduction is directly proportional to the metal content of the
fuel and the tune of the engine. In most cases, a wide band sensor will provide
accurate measurements somewhere between 50 hours and 500 hours with leaded fuel.
WHEN INSTALLED IN THE EXHAUST, THE OXYGEN SENSOR MUST BE
CONNECTED AND OPERATING WITH THE LM-2 WHENEVER THE CAR IS
RUNNING. AN UN-POWERED OXYGEN SENSOR WILL BE DAMAGED WHEN
EXPOSED TO EXHAUST GAS IF NOT PROPERLY POWERED.
The maximum temperature of the sensor at the bung (the sensor hexagon)
should not exceed 500
o
C or 900
o
F. If these temperatures are exceeded in your
application you should either install a double length bung (one inch) or the Innovate
Motorsports Heat-Sink Bung extender (HBX-1).
The double length bung is also recommended for situations where airflow is restricted.
It is NOT a good idea to do a sensor warm-up prior to starting the vehicle.
Depending on the climate and the sensor position in the exhaust, condensation can
form in the exhaust pipes. This condensation could then be blown by the exhaust
stream against the hot sensor when the car is started. The resulting heat shock can
permanently damage the sensor.
