TECH-1 Codes

[Aron Lopes Petrucci]

Hi,

I'm trying to develop an ALDL-PC link to GM cars made in Brazil (they
are Opel like).
So I'm now seraching for the codes to "talk" with this cars. They are
TECH-1 compatibles, so, I'd like to know where can I find that codes
wich TECH-1 send to ECM and tell it: reset the idle control, turn on the
fan, give me the engine parameters, etc... and how to translate the
parameters got from car.

I built an interface (Serial - ALDL) from Dave's  page at
http://www.geocities.com/MotorCity/Shop/1624/DL-RS232.JPG

In that site Dave shows a many codes and some software, but I don't know
if it is TECH-1 like. I'm affraid about send the wrong codes to ECM and
make it crazy!



Can anybody help me?

Thanx in Advance.
