ECU6 EFI system construction

[Michael J. Kupec]

Al,

Have you changed anything in the EFI.ZIP file since 3 Jan? I've tried to D/L
it tonight, but AOL keeps timing out during the transfer. If others are
having problems with getting the file, I can upload it to my web site for
others to retrieve.

Get in, Sit down, Shut up, and Hold on!

>A number of people have sent me mail indicating a desire to work on the ECU
>project - this is great!  I beleive that we can end up with a much better
>system with a dozen people each focusing on a specific aspect of the
>project than lots of people trying to do it by themselves.  If people are
>interested in this, I would be happy to coordinate the development process,
>as well as use my homepage as a central location for communicating project
>status among people (http://members.aol.com/ALIPPER/  It is also linked to
>the projects section of the DIY_EFI web site).

>In particular, we need people to specialize in the following areas:
>
>- Programming the 8051 (or derivative with advanced features like counter
>arrays)
>- BASIC programming (Preferably with experience in real-time control
systems)
>- Detailed EFI operational theory (to help guide the programmers)
>- Electronics design (with microprocessor/microcontroller experience)
>- Automotive electronics experience (dealing with noise, driving high
>currents, etc.)
>- PC board layout & routing
>- Building and testing the system on your own vehicle (for giving the
>designers feedback)
>
>There are probably many more areas that will arise as work progresses, but
>for now, this should give us a good start.  Also, if anyone has the ability
>to have balnk PC boards manufactured in small quantities for a low cost,
>that would be great (I've already tried non-professional fabrication of
>these boards, and they're way too dense and complex to have this work
>reliably).  I've had some of them made so far and paid about $130 for four.
> If we could get the cost down, that would be good.

>Someone asked for additional info on how well the system works.  I drove
>around with it for about six months and it worked surprisingly well.  It's
>still missing some "features" like an accellerator pump, has a slightly
>rich mixture at idle and the learning routines need work, but otherwise it
>was quite drivable.  Only once did I have a system failure, and that was
>due to my neglecting to put any kind of a heat sink on the injector drivers
>(I didn't think they were that hot...)

>who contributed to the effort should receive a proportional part of any
>profit.  But that's not really the point.  I'm in it for the fun and not
>for the money, as I'm sure is true with everyone here.  So...If you have
