I have a 1988 Chevy 1/2 ton pickup and I would like to monitor the ECM data
through the diagnostic connector while the engine is running. I understand
there are expensive electronic tools to do this, but I was wondering if
there is cabling and software available so that I can do this with a laptop
or PDA? Where can I get more info on the net? I'm very computer literate,
just not as they relate to cars.
===========================I just researched this same thing.....The cabling and software are just as
expensive as the scan tools. Also, being that your truck is OBD 1, there are
very limited choices for the software. Being that I was looking for
something that did OBD1 and 2, you might have better luck. Just search for
"OBD1 software" in Google you should find some stuff.

Ha ha hot dang!!! This thing really works!!! I put the cable together,
installed the software and it works like a charm! Fantastic! I'm going to
write this guy a check. This is better than the $600+ diagnostic tool at
Shucks (at least for my needs) and all for price of a used laptop that you
can get for $200 - $400. Costs nothing if you already have one. Now all I
have to do is capture the data when the problem happens.
Here's web site:
Works for me.
Thanks for your input everyone!

You built the cable yourself? I was interested in this product but I'm
not electronically inclined enough to build the cable from the
instructions on the page. I can use a solder gun and have a steady hand,
just can't read schematics. Would it be possible to detail me in on the
cable? If not, it's cool, I'll hit up one of those links they
There are tons of information on the Internet regarding GM ECM
systems. For example -
If this isn't enough, search Google for +GM +ECM
