[Diy_efi] Projects

Bill,

DeuceEFI is Andy's nick on the forum, and I guess maybe future company? His
board is called Jaguar and is his implementation of a FreeEMS hardware
design. It's suited to GM DIS and Ford EDIS systems with only logic level
ignition outputs (not suitable for correctly driving typical Darlington
ignitors). It's a compact and easy to build design with good protection and
versatile use options. I'm quite fond of it despite the niche nature of it
:-)

I've posted on this list about FreeEMS in the past, but didn't get much
response. There is plenty of scattered messy information available about
it, start at these jump points:

Regards,
