The LM-2 is primarily an air/fuel ratio meter and a multi-channel data logger, designed to help users tune engines for optimal performance and efficiency.
The LM-2 is compatible with all common fuels, including gasoline, diesel, E85, methanol, and propane.
Data logged to the SD card can be easily transferred to a PC or tablet via the included USB cable or by transferring the SD card directly.
The 4 configurable analog inputs allow you to connect and log data from external sensors, such as MAP sensors, exhaust gas temperature (EGT) sensors, or boost pressure sensors.
Yes, a weld-in bung must be installed into your exhaust system to securely mount the included wideband oxygen sensor.
The Shop Kit includes the longest sensor lead (18m), an inductive clamp, and an exhaust clamp, making it ideal for professional workshops. The Complete Kit includes ODB-II/CAN interface, an analog in/out cable, and an SD card. The Basic Kit includes the essential components for AFR metering and logging.
Yes, the LM-2 is available in configurations with single or dual O2 sensors, allowing for more comprehensive monitoring on V-engines or performance applications requiring dual exhaust monitoring.
Ensure the power adapter is securely connected to both the LM-2 and the power source. Try a different power outlet or vehicle if applicable.
Verify the oxygen sensor is properly installed and free from contamination. Allow the sensor to self-calibrate fully. Check for exhaust leaks near the sensor bung.
Ensure the SD card is properly formatted (FAT32) and inserted correctly. Check that the SD card is not full and has sufficient write permissions.
Confirm the USB cable is securely connected. Ensure the correct drivers are installed on the PC. Restart both the LM-2 and the computer.
Consult the LM-2 manual for specific error code definitions and recommended troubleshooting steps. Common issues include sensor faults or communication errors.
Setup: The LM-2 requires the installation of a weld-in bung in the exhaust system to mount the wideband oxygen sensor. Connect the sensor to the LM-2 unit using the provided cable. For Shop Kits, connect the ODB-II/CAN interface if needed. Power is typically supplied via the cigarette lighter adapter or directly to the vehicle's electrical system.
Compatibility: The LM-2 is compatible with all gasoline, diesel, and alternative fuels. It can interface with engines utilizing carburetors, aftermarket ECUs, flash programmers, and ODB-II systems.
Care: Keep the LM-2 unit clean and dry. Protect the oxygen sensor from physical damage and contamination. Regularly check cables for wear. Ensure the SD card is properly inserted and removed. Periodically refer to the LogWorks software manual for advanced features and data management.
