Innovate Motorsports LC-1 - Manual (Page 8)

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 copper heat sink (instructions below) or the
Innovate Motorsports Heat-Sink Bung extender (HBX-1).
The bung extender is recommended for situations where airflow is restricted or
the encountered heat is higher than a heat sink can handle.
It is NOT a good idea to connect the LC-1 permanently to 12V and switch it
on with a separate switch before the vehicle is started. Depending on the climate
and the sensor position in the exhaust, condensation water can form in the
exhaust pipes. This condensation water 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.
2.5 How to fabricate a copper heat sink
Use a 4” x 4” (10cm x 10 cm) sheet of copper sheet metal 14ga (1.5mm) thick. Drill a hole in the
center with the same diameter of the oxygen sensor threads ~3/4” (19mm).
Fold the sides up 45 deg and mount it between the sensor and the bung like you would a big
washer. Orient it such that the sides are exposed to good airflow.
3 First Time Use
1. Do not connect the sensor yet.
2. Switch 12V supply to the LC-1 on and wait for 10 seconds.
3. Switch the 12V supply off after 10 seconds.
4.
Connect the sensor to the sensor interface connector. The sensor must be exposed to air
for the first time calibration.
