LM-1: Digital Air/Fuel Ratio Meter
The LM-1 is the industry's first and best complete wideband tuning system.
A single self-contained unit combines a wideband air/fuel ratio sensor controller,
a 6-channel data logger, and an easy-to-read backlit LCD display. This is
the unit used by tuners, racers, and engine builders the world over.
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 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 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 LM-1 is available in various kit configurations:
1) The Basic
Kit ($345) includes the 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 ($425) is comprised of the basic kit plus the 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 ($585) is comprised of the basic kit plus the LMA-3 (AuxB
ox) 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).
