Warning!

The Oxygen Sensor used in this device gets very hot in operation.

Do not touch the hot sensor. Do not let a hot sensor touch a combustible surface. Do

not use the sensor with or near flammable liquids or gases. Failure to heed these

warnings may result in severe burns, explosions or fires.

When installed in the exhaust, the oxygen sensor MUST be connected and operating with

the LC-2 whenever the car is running. An un-powered oxygen sensor will be quickly

damaged when exposed to hot exhaust gases.

LC-2 Digital Air/Fuel Ratio (Lambda) Sensor Controller Manual Warning! The Oxygen Sensor used in this device gets very hot in operation. Do not touch the hot sensor.

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.
PAGE 3
2 2.1 Mounting and Wiring the LC-2 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.

grounding source as the device to which you are feeding the analog outputs, the easiest wait to accomplish this is to run an aux ground wire from the ground point of the LC-2 to the ground or signal ground of the device you are interfacing with. 2.2.1 3 Single Innovate Device Relay Wiring Instructions Sensor Placement Optimum bung placement will vary from application to application, but using the guideline below will ensure the longest sensor life with the most accurate readings.
PAGE 5
 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.

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. The calibration procedure requires that the oxygen sensor be in free air, this means removed from the exhaust system completely. 1. With the sensor disconnected, apply power to the LC-2.

- Thereafter calibrate twice a year or every 10,000 miles, whichever comes first Race car - Calibrate before first installation of new sensor - Calibrate once per race weekend Dyno use - Calibrate new sensor - Calibrate every 2-3 days, depending on usage 5 Software (LogWorks 3 and LM Programmer) 5.1 Download the Logworks 3 software package 1.

2. Select one of the Analog output tabs. The Analog output tab looks like this: This shows the analog output voltages versus Lambda for one of the two analog outputs. The graph display is automatically scaled to the selected voltages. For each output you can specify a minimum and maximum lambda or A/F ratio value and the associated voltages. By selecting the ‘use Air-Fuel-Ratio’ button you can program the curve by AFR instead of Lambda.

Condition. The factory defaults of the analog outputs update 1/12 of a second. The default voltage output is set at 0 volts for both the Warm-up and Error Condition. When setting the LC-2 to the slower response speed, the measured mixture data will be averaged over the response time setting before being sent via the analog output. 5.3.3 Updating the Firmware Do not update the firmware if the versions are the same or older than already loaded.

Use the appropriate sensor cable for the sensor type as each sensor has a different style connector. Spliced cable can not only affect the wideband’s performance but in worst cases it can damage the sensor and/or controller.

Innovate Motorsports’ MTS devices have two types of serial interface connectors, the legacy 2.5mm stereo and the 4 pin Molex. The following patch cables are available to interface your devices together: 4 Pin Molex to 4 Pin Molex - 4ft p/n 3846 2.5mm to 2.5mm Stereo - 4ft p/n 3760 2.5mm to 2.5mm Stereo - 6in p/n 3789 4 Pin Molex to 2.
