LM-2
Digital Air/Fuel Ratio Meter
User Manual
This manual assumes that firmware version 1.18 or later is installed.
Warning!
It is extremely important to avoid hot-plugging sensor connections. Do
not connect or disconnect the sensor connectors while the unit is
powered ON.
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 LM-2 whenever the car is running. An un-
powered oxygen sensor will be quickly damaged when exposed to hot
exhaust gases.

When installed in the exhaust, the oxygen sensor must be connected to a powered, functional LM-2 (no error codes) whenever the engine is running. An un-powered sensor will be damaged in a short period of time when exposed to exhaust gas. -
Page 9: Sensor Calibration
The calibration procedure requires that the oxygen sensor be in free air, this means removed from the exhaust system completely. 1. With the LM-2 powered off, connect the oxygen sensor to the sensor cable and the other end to the sensor input on the LM-2. -

When the LM-2 first establishes the connection to the vehicle’s ECU it will query the list of available channels, the LM-2 will then only allow a selection from this list. When moving the LM-2 from vehicle to vehicle is it important to reset the channel count to 1 and set the protocol to ‘Automatic’. -
