Great news,Tracy! At least for those of us who live
further north, that cold start function will materially cut down on cranking
needed. That morning after, cranking and the engine groaning - Tracy
showed me the EC2 on-off technique that somebody had discovered would squirt
additional fuel into the manifold - that really cut down on the cranking needed
to get started on a cold morning in Florida. But, this is a much more
elegant solution.
Thanks, Tracy. I take back all those words about the
woes of letting a hobby turning into a business - keep it up! Never plan
on retiring!
Best Regards
Ed A

Monitoring System / EC2 Primer function
Nice job Ed, that little gizzmo represents a lot
of effort but it is gratifying to see it work I'm sure.
I have never run into the cold start problems that some builders have
mentioned but Ed did show me that it can happen on a cold morning, even in
Florida. I finally got around to adding a primer function to the EC2
code and it will be incorporated in all future EC2s. If any of you cold
climate builders feel the need, a chip swap can get this function in earlier
EC2s. Contact me via email.
It works like this:
When the engine is not running and the mode select switch is set to zero,
pushing the Store switch will give a 10 ms shot on all 4 injectors. How
many shots are required for a really cold start will depend on manifold
design, temperature, injector position, etc, and will have to be determined
experimentally.

Good Point! Rusty.
Thanks! almost fell into the same trap
that Tracy did - even after my unheeded warnings to him {:>)
Of course, we are all glad he did.
Ed

Monitoring System
However, if I did decide to sell it would
probably be mid-late summer time before it happened. The current
design is somewhat labor intensive in cutting apart the board into the
front panel and Chip board, placing "sockets and plugs" on each board so
they can plug together, etc. I would need to look a ways to simplify
it a bit and I am certain the layout of the board could be improved.
Already, Finn has pointed out my resistors are mounted by their "legs"
{:>).
Looks
good Ed. As for selling them, I think I hear Tracy laughing
now, as your retirement relaxation turns into work
:-)
Cheers,
Rusty
