I am having trouble getting Winaldl to work on my 91 RS. Am i supposed to put a resistor between pin a and b to establish a link?

 

Well I don't have a specific answer to your question, but one thing that I did that was wrong was I had the grounding wire in the "E" pin. The ground goes in the "A". Took me about an hour to figure our I had it wrong. Could not figure out why it would not work.

So make sure your ground is in the "A" pin and give it a try.

Good luck.

I have alreay tried that, You have a 91 RS right? Do you have to put a resistor between the 2 pins?

 

Did you build your cable like the diagram on the winaldl site?

If you have the switching transister wired right it should work with out the resister between the two pins, no problem.

I built it according to the diagram in tbichips.com. Is that what your talikng about?

 

I bought mine on the internet. I did not build it.

 

some ecus will work with out a 10k resistor in ther some will not if your having a hard time i would try it with.

 

Ok, i tried the resistor between the two pins and still nothing, anything else i need to look at? Im pretty sure that me serial port is ok and functioning ok, and ive looked over the cable 100 times to makes sure its alright, What else?

 

go to the config spot in winaldl and make sure it is set to your ecu

 

I ahve tried that too, my ECM is 1228746, and i also tried it on some of the other, but i cant figure it out.

 

I had alot of trouble getting my serial port working. Its been so long now that I don't remember how to test the com port. Does anyone else know the test procedure?

 

try re-building the cable. Mine was pretty bad the first time i put it together. Maybe you fried some of the internals on a resistor or transistor when you touched a soldering iron to it.

This is the second cable i have used. Does anyone else know anything that i could try, this is getting very frustrating.

 

Try the 10K resistor. My 8746 will log without it for some reason, but it's worth a try IMO.

 

This is where I got my cable from. Works great.

is winaldl set to same com port as your laptop? 1/2/3 not IR. i bought mine from customefis $35.

 

Both of the f-body tbi ecms transmit all teh time. MAke sure that your computer is set for the proper com port and that the baud rate is 2400 so the signal meshes.

 

I have already tried all of that, i guess im just gonna have to break down and buy a cable or try to make me another one. And also i have seen a few different diagrams for the cable, can someone please direct me to the one that i need to use. Thanks for all the help.

 

This one is easy to build.

 

That is the one that i have, maybe the transistor legs are wrong, my dad built the cable for me so i dont know how to tell which leg is what.

 

Looking at the transistor from the wire end the base is in the middle on top, emitter is on bottm right and the collector is on the bottom left. If you look at the diagram you'll see what I'm talking about.

I'm not saying that you're as stupid as me, but I hastily included Resistor 4 when I did it the first time. It won't work if you use R4. Also, here's my thread that has a detailed picture of my cable.

Does my ALDL cable look right?

BTW, I have exactly the same car as you so it should work.
