1 LC-2
The LC-2 is a controller that controls a wideband O2 lambda sensor to
measure O2 content in exhaust gasses. In this section we will spend a
moment getting familiar with the LC-2 lambda controller.
1.
Status
Light
–
The LC-2 status light indicates the controller’s
operational status. When the controller is powered, the status light will
light up green for 2 seconds indicating controller initialization.
After the initialization, the status light will light will blink or light up
constant up to indicate one of the following operational status conditions:
Light Status
Definition
No Light
No power to the LC-2
GREEN, flashing twice a second
Sensor Warm-up
GREEN, series of quick flashes
Sensor Calibration
GREEN, solid
LC-2 operational, taking readings.
RED, series of flashes followed by a
pause
The number of flashes indicates an
error condition. See Appendix for
error code details.

Sensor Cable Connector
– Mates the sensor cable to the O2 sensor.
3.
Wiring
–
The LC-2’s wiring is very straight forward. All that is needed
for basic installation is power (red) and ground (black). The two
configurable analog output wires (one yellow and one brown) can be
used to feed external Standalone ECUs, 3
rd
party data loggers, and
AFR display gauges.
4.
Serial IN & OUT Connectors
– The LC-2’s serial connectors are
utilized when needed to program analog output settings, data log via
the Logworks software with a Windows PC, or to daisy chain with other
Innovate Motorsports’ devices.
