whether it will be activated by RPM. The user selects these options by clicking on the checkboxes as seen
in Figure 146.
Logging Mode
The logging mode is selected in the Data Logging Pass Options group box.
In Single Pass Mode, data is logged until all available memory is filled. At this point, Datalogging will stop
until more free memory is made available by erasing the current logged data. (You would typically
download your data before erasing it, unless you are certain that the logged data is not useful).
In Loop Mode, the data logging will log data until all blank memory is filled, after which, the data logging
will pause momentarily to erase the first 64kB of logged data. The data logging will then continue into this
space. This means that Datalogging will continue indefinitely until stopped. The data in memory will be the
most recent data that will fit into 448kB of memory.
The user selects these options by selecting the radio buttons in Figure 146.
Downloading Data
NOTE: Before downloading data, the user must Apply their changes using the apply button. The user
must also configure Data log Activation, and actually have some Data to download that is relevant to their
settings.
To download the data, click on the “Download On Board Data” button. Should you wish to cancel the
download while the data is being downloaded from the ECU, click the “Cancel Download” button. While
the data is being downloaded, the window will show a percentage to indicate the progress of the
download. Typically the download should take about 2-4 minutes.
When the data has been downloaded from the ECU dialogs identical to Figure 138 and Figure 139 will
appear. Save the file with the appropriate comments. This will save the file to a *.csv format which can be
viewed using the Data Viewer. The status bar will indicate the file is being processed and when it is
finished it will display the file.
Erasing On Board Data
To erase the data stored on the ECU the user can click on the “Erase On Board Data” button. The window
will display the status of the erase process.
NOTE : Once a data is downloaded from the ECU, it is good practice to remove the data from the ECU.
This will ensure the user does not download old data, which could lead to confusing results in analysing
the data.
