CarChat and cable ...

[Dale Klein]

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.......
