ECM stolen! 1994 Civic EX KA5MT

I can hardly believe it. 1994 Civic EX, 17 years old, and a professional
thief hit it. Stole the aftermarket stereo (who cares!) but then my wife
tried to start the car and couldn't. I got down there and found the ECM
was gone, gone, GONE. Dude just unplugged it, though, from the looks of
it--all connectors appear intact, and it appears he/she even left the bolts.

Killer is that I was planning to sell it within a month. Great car, runs
great, and would be happy to drive it into the ground if it fit three
car seats. I even recently replaced the timing belt, water pump, and
front brake rotors.

So the question is: a new ECM from e.g. Majestic is about $521. I
imagine I could pull one in a junkyard, but don't have the time to do
it. I found one from http://autocomputersystems.com for $200, but I
wonder if it's legit. Has anyone used one from these guys? Other leads?
I figure I could post it as-is on Craig's list, but it would be nicer to
sell a car that runs. Thoughts?

Next question: I have the service manual, but I'll be darned if I can
find info about replacing the ECM. Its location is noted in the
Electrical section, but I don't see it listed in the section index.
Could someone point me to the page? Do I simply pop a replacement in, or
is there an initialization sequence?

Thanks, folks.

I also found a post that pointed me to http://car-part.com , which looks
useful as a salvage part clearing house.

BUT: Just got off the phone with someone who was told that once you have
the part, you have to take it to the dealership to have it programmed
for your vehicle. Is that the case for a 1994 Civic? Meaning, if I take
a part #37820-P28-A02 ECM from another 1992-95 Civic and pop it into
mine, it won't work "out of the box"?

I know this isn't a part that often fails, so if anyone has info on this
I'd love to hear it.

Back to googling... ;-)

No.

It's plug-and-play. No worries.

I've even found that an automatic ECU will usually work in a manual car,
but not the other way around. But such a mismatched ECU will result in a
permanent Check Engine light, since the computer is looking for
transmission sensors which aren't there.

Doesn't often fail, but appears to be frequently stolen, probabl yon
account of how easy they are to reach. My impression is that thefts have
declined over the years as fewer and fewer of these cars remain on the
road.

Guess not in Brooklyn... ;-) I must've been lucky all these years.

Thanks, Tegger. You (and your site) were very helpful when I first
started working on this vehicle, and here you are again. Always good to
know there's a nice crew of Honda users right over here. Perhaps one day
I'll have another Honda (this one's too small to fit three car seats,
and I'm not ready for another vehicle right now). Sure have loved this car!

I remember using car-part.com a few years ago. Wrecking yards across
the country use it to list parts rather exactingly. The names and
contact info come up when one does a search there. I called a number
of junkyards at the time and all seemed legitimate.

Try also http://www.olstons.com/ . I bought a pulley from them
sometime in the last seven years and was pleased with the used part,
service, and price.

The guys at honda-tech.com change ECUs out all the time.

Glad to help.

Less and less involvement from me, though. The site is growing gradually
more and more outdated, as I've had less and less time to do much more than
answer quick questions here and there.

Usenet in general is dying; it doesn't attract nearly the audience it once
did.

Thanks, Elle. Nice to see you still here. I ordered one from a yard in
MO for $95 shipped. Hard to beat THAT price! Now I just hope that the
traffic cops here are kind. We have alternate side parking regs that
mean we have to move the car several times a week for street cleaning,
and the part won't be here till Fri or Mon (depending on how lazy our
UPS guy is feeling). So far so good.

I gotta say, that salvage yards are putting parts online is rather
amazing. Makes perfect sense, of course.

Yeah, it's pretty sad. I hadn't noticed just how sparse the posting has
been here in past months. Another board I frequent is practically dead,
too, though that's in large part because the software it concerns hasn't
been updated in almost 10 years. It's only "old-timers" that know about
NNTP these days, and its port was off by default on my school's firewall.

Personally, I despise the web-based boards a-la phpBB and the like.
Though they have some advantages, I'm of the old-school, preferring
clean, plain-text Internet communication. Heck, I read my email in
monospaced Courier most of the time...

So what are the successors to this board? honda-tech.com, which Elle
mentioned? What else? Ultimately I'm just curious, since I won't have a
car soon.

My big problem with Web is that all the Web boards I've tried or looked at
have an extremely high glitz-to-information ratio. By that I mean messages
occupy 10% of the screen, and images, smileys, flashy ads, and white space
occupy the other 90%.

I've lurked in honda-tech.com. It's an appalling hodgepodge of ricers,
aftermarket junkies, clueless newbies, near-illiterates, me-too'ers,
halitosis-sufferers, voluntary shut-ins, Walmart shoppers, flood-pants-
wearers, navel-noodlers, people who refuse to move to the rear of the bus
as others get on, and other unfortunates. And it's typical of /all/ Web
boards. Maybe I'm too old, but I just can't take to it. If Web-board
software at least had THREADING and a killfile, I might change my mind.

But then again, most of those aformentioned defectives used to inhabit
Usenet before they deserted for the glitter of Web boards, so I guess I'm
not missing much...

And staying that way?

It seems to be working, business-wise, so it sure is a boon for
hobbyists without a good set of wrecking yards near their homes. Good
to have your preliminary report.

Contrary to Tegger's opinion, I think honda-tech is better than the
usenet car groups. Just the pictorial DIY reports that many hobbyists
post all by themselves are invaluable. I am picking up all sorts of
good anecdotal reports on the 01-05 Civic generation that alert me to
possible problems. The mods there do a good job of making it a useful
web site. The ad content is low in my opinion.
