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.

World's only fully-digital wideband controller. Up to 6 Channels of data logging. Portable/ Handheld. Display both A/F and Lambda readings in real-time. Auto calibration to compensate for changes in temperature, altitude, and sensor condition. Two user configurable analog outputs. LogWorks - award winning tuning software.

The LM-1 Wideband Controller / Data logger can sample and store 6 channels of data- air-fuel-ratio and up to 5 other sensor data channels- 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 LogWorks software or any standard spreadsheet program:

The Innovate LM-1 also features two analog outputs to connect to analog gauges, dyno computers, ECUs, piggyback controllers, and other devices with analog inputs. Analog output 1 comes setup from the factory ready for narrowband simulation; analog output 2 is configured as 1 volt = 10 AFR (.6 lambda) and 2 volts = 20 AFR (1.3 lambda). With the provided LM Programmer software these analog outputs may also be configured by the user.

The Innovate Motorsports LM-1 is available in various kit configurations:

1. The LM-1 Basic Kit (this p/n 3723 you're looking at here) includes the Innovate Motorsports LM-1 meter, a Bosch wide-band oxygen sensor, 10 ft sensor cable, cigarette-lighter power adapter, serial cable for PC connection, 9V battery, exhaust bung and plug, CD and quick-start guide.
2. The RPM Kit is comprised of the basic kit plus the Innovate Motorsports LMA-2 (RPM Converter). This cable contains a circuit to convert a tach signal into an analog RPM signal that can be logged by the LM-1. This cable also has 4 additional terminal screws to tap into and log other 0-5 V analog sensors from your vehicle.
3. The AuxBox Kit is comprised of the basic kit plus the Innovate Motorsports LMA-3 (AuxBox) input Expander Cable. The AuxBox will give you the choice of picking sensors existing from the vehicle or use the 5 internal sensors. The five internal sensors are: RPM conversion (from a tach signal or inductive clamp), Manifold Air Pressure (MAP or Boost), Cylinder Head Temperature (CHT) or Exhaust Gas Temperature (EGT), Acceleration, and Injector Duty Cycle (Dwell).
