Whether you drag race, rally, sprint, kart, drift, autocross, street performance or any other form of motor sport, an accurate air/fuel reading takes the guesswork out of tuning your carburetor or fuel injection. Older, narrow-band gauges tell you if you are rich or lean, but not by how much. The Innovate LM-1 tells you exactly where your air/fuel mixture is under any load, and the meters self-calibrating circuitry compensates for changes in altitude and sensor condition. The LM-1?s wide band sensor works equally well on gasoline, alcohol or diesel. The LM-1 is also a 6-channel data recorder, allowing you to sample and store air/fuel, and up to 5 additional sensors, 12 times per sec., for up to 44 minutes. The data can be downloaded to a PC with the included serial cable and LogWorks software, so you can view, graph, compare, and save multiple sessions. View live data on the backlit LCD, or log data for later analysis- with the LM-1 you can do both. Maximize horsepower, save your engine, or track down tricky fuel system problems. All Innovate products share a common communications protocol, and are scalable and configurable so you can expand your tuning system to include additional sensors later. Measure, capture, view, and analyze- now you?re tuning. The LM-1 RPM Kit includes: LM1, RPM Converter (Aux Input #2), Bosch 5-wire Wideband 02 Sensor, Analog Output Cable, 10ft. Sensor Cable, 10ft.
