Post subject:  Board Usage Statistics

IE, where did they all end up? At least 23 running engines so far, half DIY, half boards, mostly Jaguars.

I'm hoping to document what proportion of people who buy a board end up using it on an engine. I guess we'll need a few classes of what happened. I'll do one post per spin of boards and a comments thread for feedback on how to categorise and/or increase success rates. This doesn't include DIY builds or TA purchases or other hand built one-off prototypes. Only batches spread around.


  • Taken to examine, not use.
  • Taken to use, never built.
  • Taken to use, built by user, never ran.
  • Taken to use, built by provider, never used.

List Of Hardware Spins

  1. 37 * Infamous Puma Spin 1 (first and last Puma board)
  2. 5 * Jaguar A3 (first bulk produced Jaguar)
  3. 5 * Jaguar A3.1 (KennyBug batch of Jaguars)
  4. 11 * Jaguar 0.4-alpha (first Jaguar with good ignition hw)
  5. 7 * PowerEFI F16 V1 (closed source secret squirrel project)
  6. 10 * Jaguar 0.6-alpha (first near-flawless FreeEMS board)
  7. 5 * OnionBoard V1 (companion board for CPU dev board)
  8. ? PowerEFI F16 V2, not included yet. (closed source secret squirrel project)
  9. 5 * Jaguar 0.6-alpha (Impregacy batch of Jaguars)
  10. 5?or? ruzki ms-compatible boards, not included yet. (December 19th ordered)
  11. 50 or 51? Jaguar 0.7-alpha, not included yet.

Total: 80 FreeEMS compatible PCBs professionally manufactured! Final result: 20/80


If I forget something, a user, a board, a spin, etc, tell me in the comments thread: viewtopic.php?f=9&t=2276

Post subject:  Puma Spin 1 Usage Statistics

A whopping and optimistic 37 boards made it out into the wide world

1 Marcos ran his car for 5 minutes on top of a hill at idle.
1 I thrashed and eventually blew up my truck for a couple of weeks. (no fault of Puma or FreeEMS, my fault) Then moved it to the Hotel Hyundai. It now lives on my desk for testing.
1 Preston ran the mighty 4AGE from one

Preston built a few more, including mops' one.
Johntramp built one and never quite got it working.
Craig built one and never quite got it working.

5 went to San Diego in the care of Abe and never came back.
5-10 stayed in Argentina never to be seen again.
1 went to Joseph Davis and collected dust.
1 went to gimpy in the US and is dusty by now.

etc, more here: viewtopic.php?f=38&t=983

Final score: 3/37

Post subject:  Jaguar A3 Usage Statistics

Lessons learned, a modest 5 boards made it out into the wide world. Additionally KennyBug had some made.

Andy ran his deuce on one.
I ran secret unlucky 13 on one.
Mike ran his 1987 383 V8 on one.
Hentai ran his Miata on one. Soon to run a different Miata!
Jeff ran his Tacoma on one.

All 5 ran.

More info: viewtopic.php?f=27&t=1848

Final result: 5/5

Success rate:


Great work, Andy and everyone with an A3! :-)

KennyBug quietly produced another 5 boards out of Git without telling anyone:

KennyBug has 3 of his own spin of A3.1 or similar.
Mike has a blank KennyBug version, unused, likely won't be.
Dan has one KennyBug version, built for bench, won't run.

More info: viewtopic.php?f=67&t=1599

KennyBug's hit rate 0/5


Lesson: Don't go out on your own on things. Keep in touch with the core devs.

Post subject:  PowerEFI F16 V1 Usage Statistics

In a dark dusty corner, Sean secretly had 7 V1 F16 boards printed

Sean is running his R1 with one.
Sean briefly ran his LT1 with one that didn't work properly.

2 ran.


Abe had a fully built one collecting dust and making me and Sean both mad. (a team!) But then returned it to Sean, who is now modifying it to go on his Camaro!

5 blanks remain with Sean AFAIK. 1 reserved for me.

More info via Morse code in the dark, encrypted.

Final result: 2/7
