Welcome to FOME
Fome is a new project intending to deliver a user focused high feature ECU with open source hardware options and open firmware that give control back to the user, owner and driver.
As there are many complicated topics to cover we recommend that you start with the topics in the "intro" section to the left. The first page to view should probably be the FOME Overview page.
