LM-1w/ RPM Kit : Digital Air/Fuel Ratio Meter Innovate Motorsports Item #: INN3724 Our Price: $429.00 Description: 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 meters digital signal processing technology provides data on exactly how rich or lean an engine is running at load. The LM-1 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?Kit 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.
??
The?RPM Kit?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.
