Innovate Motorsports SCG-1 - Manual (Page 15)

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. Other settings, of course, are easily
programmable.
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.
When setting the SCG-1 to the slower response speed settings, the
measured mixture data will be averaged over the response time setting
before being sent via the analog output.
4.2.3 Updating the Firmware
Do not update the firmware if the versions are the same. A
firmware update should only be necessary if there has been a new
release that specifically fixes a problem that you are experiencing with
the controller.
