Re: CarChat and cable ...
Just started listening here.
On a '95 Z28 PCM.....
I made the 2 trans converter from Sanja's picture, using port power, and it
almost worked. I forget now exactly what the symptoms were, but it didn't
work 100%. The two diodes were added upon Andrew Mattei's suggestion, and
it has worked since. It has successfully reflashed the pcm a good half
dozen times. Seems too simple to be true, but it works, and it is pretty
small cable wart too. Don't you love cable warts.......

For new users I'd suggest the two transistor interface that Sanjaya
Vatuk has documented at http://www.andywhittaker.com/ecu/aldl_hardware.htm
However Andy has a new note there:
I'm hearing that you may have to add two diodes in series with the 10K
resistor in the base of upper transistor in certain applications for
reliable operation.
I'd like to hear what experience/problems that people have had.
