This thread is a summary of my FreeEMS truck build.
This vehicle is the first in the world to run a Puma board (as designed by Marcos/nitrousnrg) and the second to run FreeEMS! It's the first to run FreeEMS with ignition, first with COP, first with boost, first in New Zealand, etc etc. It's pretty special to me for a variety of reasons, not least of which is that I learned to drive in it. It's been with me for 2/3 of my life and i've had a lot of good times, and bad, and fond memories in, on, and around this truck.
The truck used to run a moderately modified ms2e/V3 with various short falls and flaws with the original design fixed or patched. Hence the db37 connector, during development I wanted to keep it mobile and plug and play compatible with my custom ms box. I'm happy to say that I will never run MegaSquirt on any of my vehicles again. Man it felt good to type that! :-) If you've got the time, skill, and desire, you should get involved in testing FreeEMS and helping it mature and grow too.
on with the pics :
my customised Puma board, running 4cyl COP using the built in XOR driver chip to control the ignitors.
