6. Recording other vehicle data with the LM-1
6.1. Overview
The LM-1 has the capability to record other vehicle data from other vehicle sensors while driving
so as to compile a complete log of engine data. For example, the optional LMA-2 cable provides
input for up to 5 other sensors (RPM plus 4 others) to the LM-1 whose data values will be
recorded.
Never connect the Aux inputs to 12 volt or battery power. Connecting the
inputs to sources that generate greater than 5 volts will result in damage to the
LM-1.
The LM-1 simply records the voltage on each input connection with a resolution of 10 bits (a
precision of 0.00488 Volt). LM-1 will record up to 44 minutes of data from all sensors including
lambda. A new value for each sensor is recorded every 0.08192 seconds (roughly 12
times/second). Software to view and analyze recorded data log files is included with your LM-1
and can also be downloaded at
www.tuneyourengine.com.
6.2. Recording
To record data in the LM-1, press the 'Record' button. The LM-1 will display a blinking 'R'
between the lambda and AFR/O2 measurements while recording. To stop recording, press the
'Record' button again. Each time you start recording a new record ‘Session’ is created. A total of
44 minutes of data can be recorded in the LM-1. If the internal memory of the LM-1 is full, the
blinking 'R' will not show when starting a recording session. Instead it will show an 'F' for 'Full' for
a few seconds. To erase all recorded data, press and hold the 'Record' until 'RS' (for ReSet)
shows between lambda and AFR/O2 display.
Use the included LogWorks software package to download recorded data.
To erase all recorded data, press and hold the 'Record' until 'RS' (for ReSet)
shows between lambda and AFR/O2 display.
