Hi Tracy;
I'd be very interested in the software code for an Arduino/EC3 when it is ready. My Dad has given my 14 year old son his old jeep as a project to work on for the next few years until he can drive legally. I had already been considering converting it to EFI as a good learning experience for him and now hearing that the EC3 code will be available has convinced me that we should do this. I'd already planned to buy him his own Arduino starter kit just because I think there is a lot of educational value there, but with a goal of building his own EFI for his own Jeep, there will be a lot of motivation to learn. And it will be a great platform to test the design before possibly trying it in any future aircraft builds.
