"The standard LM-1 includes a Bosch wide-band oxygen sensor and cable, cigarette-lighter adapter, serial cable for PC connection, 9V battery, exhaust bung and plug, CD and manual. The LM-1 ships with a Bosch sensor, however, it can also function with other wide-band sensors, including Honda/NTK and VW sensors.
