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 digital signal processing technology provides data on exactly how rich or lean an engine is running at any load. The LM-2 has a self-calibrating circuitry that also compensates for changes in temperature, altitude, and sensor condition.

Review: Funktioniert nicht und verkäufer reagiert auf keine reklamation
Review: This Air fuel ratio meter is a must have for tuning a carburetor engine. The user manual is fairly simple and the meter is easy to setup and use. No need to wait and schedule time on a chassis Dynamometer and pay for it over and over. One time Dino tuning a car can easily cost more than this air/fuel ratio meter. I have also used it to read/clear OBDII codes on several cars and it has worked great for that too. I am very pleased with this product and would recommend it to friends.
