I have been working on a low cost open-source HW & SW controller for about a year now. The first serious hardware prototype is coming along OK so I thought I would share the project.
It is a shield plus Arduino concept but I am hoping to make it multi ARM Cortex project board friendly. The first Arduino controller used is the Due SAM3X8E.
The purpose of the project is to give hobbyists a open source ARM based EFI controller with plenty of I/O and a built in wide-band sensor controller using very cheap and widely available parts. The software is pretty modular - I am hoping this will help with collaboration. I could do with some help with SAM3X8E if anyone is knowledgeable and interested!
The PCBs can be available at cost or make your own with the Gerber files.

Any collaborators or helpful feedback would be great
