When using the MEITE, there are two main modes of operation, on-line, and off-line.


On-line is when you are successfully connected to an Engine Management System, and the data shown is a live representation of what is contained within the ECU’s memory. Off-line is a mode used to edit base maps and calibration files ‘on the bench’, which can at a later time be sent down to the ECU once connected.


You can enter off-line mode by starting MEITE, and then loading a calibration (without being connected to an ECU). MEITE will ask you to confirm you wish to work in off-line mode, and then will load all of the calibrations data. The DROs will be shown with greyed out text to indicate your on off-line mode, and the lower right connection status will also show "Off-line". The bottom status bar will also show the currently loaded calibration name.



The current connection status is shown in the status bar, at the lower right of the screen - note that the ECU requires power to be connected. If for whatever reason communications to the ECU are lost, then clicking ‘Connect’ from the File menu will attempt to reconnect to the ECU, and will then pull the data directly from the ECU.
