Sensor Controller Manual
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.

- Page 1 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.
- Page 2 2. 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...
- Page 3 (-) 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.
- Page 4 LC-2 to the ground or signal ground of the device you are interfacing with.
- Page 5 O2 readings. Sensor Calibration Once the LC-2 has been wired and a suitable location has been found for both the controller and the sensor, it is time to perform the sensor calibration. Innovate Motorsports’ ‘Direct Digital’ wideband measurement technology...
- Page 6 Again, make sure that the sensor is in free air (not in the exhaust). 3. Power up the LC-2. The status light will light up green for 2 seconds while the system initializes. The status light will then start flashing green twice a second indicating that the sensor is heating up to it’s...
- Page 7 LM Programmer is used to update firmware, change fuel types, change sensor type, and program the two analog outputs. 1. Connect the OUT port of the LC-2 to the provided serial programming cable. Connect the other end of the serial programming cable to your computer.
- Page 8 Click the ‘Program’ button to upload the new programming data into the LC-2. Once the unit is programmed the ‘Program’ button will grey out. Factory Programmed Defaults: Analog Output 1 is programmed to output between 0 V for an AFR of 7.35 (gasoline) and 5.0V for an AFR of 22.39.
- Page 9 The LC-2 is multi sensor compatible with the Bosch LSU 4.2 and 4.9 sensors. In order to go from one sensor type to another the LC-2 must be connected to the LM Programmer software and the appropriate sensor type must be selected.
- Page 10 IN and OUT connectors to form one single synchronous log. MTS log chains can consist of a single unit connected directly to a laptop (connect your LC-2 directly to a computer,) two units, or multiple devices connected together, up to 32 channels. Below are...
- Page 11 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...
