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.


* 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 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.

lol innovative wideband?!?!? yes thats ******* good

 

Many go with the LM-1 it is good, along with the AEM one...

 

Whats the difference between this and the aem one other than this not being a gauge. How complicated is it to tune your a/f ratio with these?
