8.4. Programming the analog outputs
Select one of the Analog output tabs. The Analog output page looks like this:
This shows the analog output voltages versus Lambda for one of the two analog outputs. The
graph display is automatically scaled to the selected voltages. For each output you can specify a
minimum and maximum lambda value and the associated voltages. Below the minimum and
above the maximum lambda values the output voltages stay constant at the associated
programmed voltage.
By selecting the ‘use Air-Fuel-Ratio’ button you can program the curve by AFR instead of
Lambda.
This does not change the programming, only the representation of the data. When
programming by AFR the LM Programmer converts the number to Lambda before
programming the LM-1.
Click the Program button to download the new data into the LM-1.
As factory programmed the first output simulates a typical narrow band oxygen sensor. The
second output is programmed to output between 1.0 V for an AFR of 10 (gasoline) and 2.0V for
an AFR of 20. This allows to connect it to a digital voltmeter or panel meter (0.2V input) to show
directly AFR. Other curves of course are easily programmable
