Captured Values Dialog


Use this dialog to define the items the ECU will capture when you start a new datalog.  The ECMLink application datalogs raw values from the ECU.  Internally, those raw values are fed through a number of converters to produce more "natural" display values.  For example, most people want to see engine speed as RPM.  But the ECU doesn't directly work in RPM terms.  It directly tracks the time per 1/2 revolution of the crankshaft (listed in the ECMLink application as RawMPR).

The list on the left (Displayable Items) is a list of all "natural" display values that can be calculated from the current device.  The list on the right (Raw Values to be Logged) is the list of raw values to be logged currently from the ECU.  The items in the left list that are bold faced are those that can be calculated from the current list of items on the right.  In other words, the bold faced items in the left list are the ones you could currently see in a new datalog.  The other items in the left list are available to be logged but are not currently displayable because the raw items necessary to display them have not been added to the ECU's list of items to log yet.

Add to device

To make an item in the left list displayable, either double click the item or highlight it (as well as any others you want to log) and then click the Add to device button.  That will add the missing raw items to the list on the right.

Remove

To free up space in the log buffer or to try to increase the datalogging sample rate, you can remove items from the list of items to log by highlighting raw values in the right-hand list and then clicking the Remove button.  This will remove those items from the list to be logged (as best it can...some items are hardcoded to always be logged) and update the list on the left to indicate which items are still displayable and which are not.

Show Usage

To see which displayable items are derived from any given raw item (or collection of raw items), click the raw items of interest and then hit the Show Usage button.  When you do, the displayable items in the left list that are derived from the raw items selected in the right list will be highlighted.
