Hi,

I need to make a cable to scan my '91 Vette. Does anyone know if I can use this layout? I'd like to use TunerPro as it is free ...



Best wishes

You're better off just buying this. It's cheap. http://aldlcable.com/sc/details.asp?item=aldlobd1u

That's what I would do if I would live in the USA but I guess a DIY-project could be faster than shipping to Germany and in addition it would give me a chance to learn something new ...

Problem with that circuit is it uses a RS232 serial interface which requires a serial port on your laptop which I doubt you have
( unless you own a pre '05 laptop ?)

The serial -USB adapters you can get have been mostly shown not to work with the ALDL signal

Of course you could get really serious

Wow, thanks for that link!

Serial post is not a problem. I can get a PCMCIA-Card with serial or use one of my employers laptop computers as we have a lot of dataloggers with RS232 ...
