The LM-2 combines an air/fuel ratio meter, a full-function 32-channel datalogger, and powerful software to deliver a complete tuning workshop for less than the cost of one dyno day. Whether you have a piggy-back fuel controller, race carb, aftermarket ECU, ODB-II tuning software, or a flash/chip programmer, an LM-2 is the tool you need to dial in maximum HP. The meter's award-winning digital signal processing technology provides data on exactly how rich or lean an engine is running at any load. The LM-2's self-calibrating circuitry also compensates for changes in temperature, altitude, and sensor condition. The new LM-2 "Basic" Kit (Single Wide band O2) ONLY includes the LM-2 meter, Bosch wide-band oxygen sensor, 8 ft sensor cable, cigarette-lighter power adapter, USB cable for PC connection, weld-in bung and plug, Log Works software CD, and quick-start guide.
