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 LM-2 also features two fully programmable linear analog outputs to connect to analog gauges, dyno computers, ECUs, piggyback controllers, and other devices with analog inputs. With the provided LM Programmer software these analog outputs may also be defined by the user. Patented DirectDigital™ wideband sensor control, 100% digital wideband air/fuel ratio technology!
