Mounting and Wiring the LC-2
2.1 Mounting
The LC-2 controller body should be mounted inside the cabin or in another
dry, protected location away from the elements. Physically mount the unit
away from all ignition or stereo components and other potentially RF or EMI
emitting sources.
Route the sensor cable in a manner that avoids contact with the exhaust
piping and other extreme heat sources that could melt the cable. Also avoid
routing the sensor cable near ignition components or other sources of RF
(radio frequency) and EMI (Electromagnetic interference).
2.2 Wiring
The LC-2 has 4 stripped wires.
1.
Connect the
RED
wire to an isolated switched 12V source in your
vehicle. A switched 12V source goes ON as soon as “key on” power
is active. The circuit to which you will pull power from should be able
to support a 3 amp draw. Make sure this connection is protected with
a 5A fuse.
Circuits that share power with the vehicle’s stereo, ignition system,
ECU, lighting, or fuel pump should not be used. When in doubt, create an
additional circuit using an automotive relay available at any automotive parts
supplier. See the next section for a relay installation diagram.
2.
The
BLACK
wire should be grounded to a solid ground source. The
best possible ground source would be the battery ground (-) post.
If other Innovate Motorsports devices are going to be daisy-chained
along with the LC-2, it is recommended that all devices be connected to a
single ground point, ideally the battery ground (-) post.
3.
Optionally, the
YELLOW
(Analog out 1) and/or
BROWN
(Analog out
2) can be connected to the analog inputs of other devices such as
data loggers, aftermarket programmable ECUs, or AFR display
gauges. If either one or both of these wires are not being used,
isolate and tape the wire(s) in an out of the way location. Each of
the two analog output wires can connect to one device that can
accept this 0-5v potential output.
The default analog outputs are as follows: Analog output one (yellow) is 0V =
7.35 AFR and 5V = 22.39 AFR. Analog output two (brown) is 1.1V = 14 AFR
and .1V = 15 AFR. Note: The LC-2’s ground should share the same
