Firmware is the programming code that Genboard executes to calculate fueling and ignition parameters based on inputs from sensors such as air pressure, temperature, etc. Firmware is stored in memory on Genboard and is accessable through the Bootloader.
All firmware releases are listed in the wiki on the GenBoard/UnderDevelopment/FirmwareChanges page. A link to download the latest package is listed along with the changes made since the last release.
It is highly recomended to backup (see Section 6.1, “Backup” ) the settings in the Genboard module before upgrading the firmware.
The MegaTune package matching your firmware also contains tools which make firmware upgrades much easier to complete. To upgrade the firmware on your Genboard:
Without the tools included with the MegaTune packages, Perl must be installed on the computer to execute the bin/prog.pl script necessary to upload the vems.hex file containing the firmware to Genboard.
With the tools included with the MegaTune package, execute the script named 'upload-firmware.bat' to send the firmware to Genboard.
