The MEITE includes the ability to update connected ME products with new firmware versions as they become available.


To access the Firmware Update Tool, ensure you are connected to a system in the usual manner above, then from the main menu ECU -> Firmware update, the following dialogue will appear:

The connected devices details are shown on the left boxes, including its product code, type and definition file version, as well as the current firmware version on the device.


After selecting a new firmware file via the browse “...” button, (only *.mefw are supported), the new firmware information is shown in the rightmost boxes.


Newer versions of firmware for your product may be available from our website.


Simply press ‘Update’ and follow the on-screen prompts. Note that any current calibration is saved to disk automatically.


Be sure to unplug ignition coils if told to do so.


If you are updating to a newer definition file of your product, the MEITE will automatically extract and store the new definition data from the MEFW file, and add it to its internal library of definition files, or it will connect to our online server and download it automatically when you first connect to a new ECU. (Ensure you have an internet connection.)
