900- Electric and Data Acquisition
After making changes to the project, which are made online, the configuration
must be downloaded to the car in order to ensure that the computer and car
configurations match.
If the MS6.4-ECU status message is yellow after connecting to the car, this
indicates that changes were made offline, whereby the parameters between
computer and ECU differ.
Afterwards a message asks whether an UPLOAD or DOWNLOAD is desired.
Attention
In this case, a DOWNLOAD should never be implemented, but first an UPLOAD
to load the ECU dataset to the PC. Now it is necessary to make the desired
changes and to copy the work page to the reference page.
The MS6.4-ECU status LED must always be green.
