LM-1 Digital Air/Fuel Ratio Meter Kit (Inn3723)


Tuning an engine for maximum power previously required long trial-and-error sessions on a dynamometer. With the LM-1, 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-1’s
self calibrating circuitry also compensates for changes in temperature, altitude, and sensor condition.
The instrument can sample and store the air-fuel-ratio and the other sensor data internally in operation for later analysis on a personal computer.

At a sampling rate of 12 samples/second the instrument can store up to 44 minutes worth of data in non-volatile memory. The data can be downloaded to a personal computer using a standard serial port and viewed/analyzed by the included software or any standard spreadsheet program.
