Advanced Measuring Values cont. - Section 13-B
VCDS lets you save a list of Advanced Measuring Values, to be easily accessed later on.
For instance, if you often log Vehicle Speed, Engine Speed, Intake Air Mass, and Ignition
timing, then you can create a file to quickly load those selections again. To save a set of
items, click on the VCDS logo found on the top left corner of the item selection window, and
then select "Save selection to file":
Give the file a name and specify the directory if desired. To load a set of previously saved
items, click on the VCDS logo found on the top left corner of the item selection window,
then select "Load selection from file". Locate the previously saved file and click [Open].
Sample Rate: The amount of data acquired in a given amount of time is determined by the
controller in the vehicle. Selecting a greater number of different Groups will result in slower
sampling so momentary "spikes" or "dips" will be harder to capture. In Engine controllers
using KWP-2000/CAN/UDS, there is a [Turbo] button to significantly speed up sampling,
for example over 30 samples per second when logging a single group in our Touareg. The
controller will remain in this High-Speed mode until you exit the Advanced Measuring
Blocks screen. This function is only available when using a HEX Interface.
[Graph] will open up VC-Scope a plug-in for VCDS that allows you to graph Measuring
Group Information and display customizable virtual gauges. For more information, see the
VC-Scope section of this manual (section 32).
You can [Log] the data from the Advanced Measuring Blocks screen. For more information
see the Data Logging section of this manual (section 8).
If you'd like to record just a snapshot in time of the current readings in each group, click on
[Save]. This will save the results to your PC, typically in your VCDS\Logs directory
When you have one or more measuring group with speed (km/h) in it, clicking on
[Acceleration] will bring up the Acceleration Measurement window, which allows you to
enter start and stop speeds and distances. This is described in the Acceleration
Measurement section of this manual (section 14).
Use [Done, Go Back] to return to the Open Controller screen.
