I am looking for a program to read the serial data stream from a 95
Cadillac Northstar Computer. I know that error codes are normally
displayed through the Heater control displays. This northstar has been
installed in a Lamborghini replica ( www.lambobuilder.com
<http://www.lambobuilder.com/> ) with a modified computer from Howell
Engine Development and as such do not have that display available to me.
The diagnostic port that Howell supplied with the wiring harness will
not work with a Tech II or other scan tool. I am having engine problems
see http://www.fiero.nl/forum/Forum2/HTML/036147.html and cannot read
any error codes.

I have a ALDL device that I can connect to the serial data wire but have
no program to read the output. Any suggestions would be appreciated.
