test bench was Re: Old 486 Board for ECU? Why?

[Frederic Breitwieser]

There are more benefits than what is obvious.  For something like an ECM, in
a car, full time, its gross overkill.  A motorola or hitachi or zilog
process, as the OEMs use, is cheaper, easier to manufacture, smaller, and
certainly as plug and play.  Change code, change wiring harness, start car.
This is what the OEMs do, as we all know.

The main advantage for me, is I have boxes of these things.  I also
understand the architecture fairly well.  I'm in the
PC/LAN/Infrastructure/Server industry.  My learning curve is much smaller
than if I attemted to solder together the EFI332 project.

And that's cool :)

have been following this thread and don't really see the benefit in an
x86
based ECU, I do however see the benefit in using it for something like a
test bench, where inputs to an ECU could be simulated. are there any
inexpensive 8-channel DAC boards out there that would make this easy
(don't
figure for this that ADC would be needed).
