Any hands on experience with them?
I haven't used their products but another member of the Planet Isuzoo forum who's well-acquainted with the equipment and program recommended them. They do sell an Android app "ALDL Scan" that goes with their adapters.
Check out their user guides:
Far as using the free WINALDL program with an adapter harness, I had a bunch of bookmarks from TBIchips but apparently they're out of business, the website no longer exists.
I found this site selling 12-pin and 16-pin USB to ALDL cables:
So that should work too. The Isuzu OBD1 systems don't have a standard ALDL connector, so we have to get the bare-pin version and just hook right up to the data wire in the connector.
Here's another site selling OBD1 USB/ALDL cables:
aldlcable.com
The WINALDL program gives a lot of useful info but can be a bit hairy to interpret unless you know what you're doing.
That 1st site's android app might be a bit more user friendly.
Of course there are other apps that you can use like the one from the 2nd link and it looks even better:
play.google.com
And the Reddevilriver site had a link to Tunerpro which looked promising. Their cable works with that program as well:
I even found an old thread on building your own USB interface cable for dirt cheap. How 'Bout That!

$12 USB ALDL cable-easy tutorial for cluster mod
First post...here goes nothing. If you're thinking about the shift light/logo/etc cluster mod but $65 for the required cable seems less than appealing, read on. Total cost including shipping for me was $12.04. Supplies: FTDI FT232RL USB to TTL Serial cable - ebay is where I bought mine...

Just for fun I downloaded the owners manual for the Innova 3123 I link above and skimmed thru it. The impression I got was that the Innova 3123 is a $40 paperclip.
