that includes drivers. Make sure that nothing is connected to the IN
port of the SCG-1
2. Power up the SCG-1.
3. Launch LM Programmer. The LM Programmer application can be
launched from
Start->Programs->LogWorks3->LM Programmer
from
the Windows task bar.

Programming Analog Output
Connect the SCG-1 to the computer and launch LM Programmer. Select the
Analog Output tab. The analog output configuration screen shows voltage
versus Lambda for the analog output. The graph display is automatically
scaled to the selected voltages values. The configuration screen allows the
user to specify a minimum and maximum lambda or A/F value to a
corresponding voltage range.
By selecting the ‘use Air-Fuel-Ratio’ button you can change the displayed
unit of measure for mixture by AFR instead of Lambda. This does not
change the programming, only the unit of measure displayed in the
configuration screen.
Click the ‘Program’ button to upload your modified A/F or lambda scaling
data into the SCG-1. Once the unit has been programmed, the ‘Program’
button will grey out.
Factory Programmed Default:
The analog output by default is programmed to output between 0V at 7.35
AFR to 5.0V at 22.39 AFR.
4.2.2
Advanced Analog Output Programming
The ‘Advanced’ button allows the user to set the analog out update speed
and the voltage output during sensor Warm-up and error conditions. The
factory defaults of the analog outputs update 1/12 of a second. The default
voltage output is set at 0 volts for both the Warm-up and error conditions.
