Selecting a greater number of different Groups will result in slower sampling so momentary "spikes" or "dips" will be harder to capture. The amount of data acquired in a given amount of time is determined by the controller in the vehicle. When you have one or more measuring group with speed (km/h) in it, clicking on will bring up the Acceleration Measurement function, which is described on the Acceleration Measurement page. Locate the previously saved file and click. 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". Non-UDS modules will have file name extensions starting with "a" like ".a01" while UDS ones will start with a "u" like ".u01". Give the file a name and specify the directory if desired. 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":

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. VCDS lets you save a list of Advanced Measuring Values, to be easily accessed later on. Use the data entry box on top to filter only the items containing the word you enter such as "time" shown here. For controllers using the UDS/ODX/ASAM protocol, the naming of each Location should coincide with factory identifiers for various data objects like IDEnnnnn. Check each value you would like to show and uncheck each that you would like to remove. The Advanced Measuring Values function has two screens, the main one shown above and the Item Selection Window shown below.

For controllers using the UDS/ODX/ASAM protocol, the "Group UDS requests" checkbox can speed up sample rates. On modules using the UDS/ODX/ASAM protocol, the Measuring Blocks function is not available and you MUST use Advanced Measuring Values instead. On non-UDS modules these can be from as many as 12 different Measuring Block Groups, but this function is available only when a label file exists for the control module being accessed. This function expands on the Measuring Blocks function and lets you select up to 12 measuring values from a single control module using a selection dialog that shows the contents of the measuring values.
