Tuning an engine for maximum power previously required long trial-and-error sessions on a dynamometer. With the LM-2, precise AFR measurement allows the user to correctly adjust many variables- including carburetor jetting, fuel injection, turbo fuel curves, etc.- without long and expensive dyno sessions.
The meter’s 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.
