Digital Dash Compatibility

[Terry/Carol Kelley]

I changed the 92 3800 Supercharged code to work with the 88 DIC in the
Ciera. I know a far amount on how it works. The question is if the ECM
outputs the messages at the same baud rate as the dash. I think the 89 Vette
is 160.

Email me privately if you like.
