I decided to try and see if I can get a datalog on my car so that I can better read it.

Anyway, I went ahead and downloaded that WinALDL program that I got off the sticky in this forum. I searched for my reference number and got that.

When I connected the cable to my ECM...I had loaded up the program and to my luck, I got no readings at all.

To make sure I didn't goof, I went ahead and double checked on the number and it was correct.

I shut off the computer, and I shut off the car. I rebooted the computer, loaded the program once more than I start my car up. Still nothing. And I mean the cable is in full contact with the ECM.

So I do it the other way, I start the car up first then, boot the program, and still nothing came my way.

Ultimately, I was kind of disappointed because i wanted to get accurate readings on my car, and when I found out that the program WinALDL has a diagnostic section, I needed to get my car read so that I can locate my damn miss.

I don't know where I went wrong, or what I did wrong, its the correct cable (OBD1 type) and it fit snuggly over my ECM without any problems. Everything else was connected as well.

Anyone have any ideas as to what went wrong?

 

what kind of OB1 cable is it and where did you get it at? GM uses differnt pins on the same OBD1, what works for a TPI won't work for TBI. I do belive there are instructions on the WinALDL site to make a cable that works.

 

well I tried to use my friend's cable, he has a 350 LT1 though...



Did I make a mistake?

 

comm ports match? that was my mistake.

 

wait what, I am just saying that the cable fit snuggly over my ECM, no problems there...should I try another program, I tried to use datamaster too, but, it didnt work either...is my ECM basically dead.
lol

 

No. You wouldn't be able to use a cable from a LT1 car. The aldl cable for our TBI cars is very simple, it's two pins, plugged into the ALDL port under the steering wheel. One pin is ground the other is the ALDL data port. The WinALDL site shows how to connect this. You may have a cable with a 10k resistor wired in it, you don't want that in the circuit. Check the winaldl site to see how it hooks up.

 

yes I suspected just as much, oh well I guess...I emailed a cable making dude and he has yet to get back to me so I will see how much it costs to get me the cable made for me...

 

i would consider a usb cable if your port is usb. rather than serial with usb adapter. i would buy the moates product. it works. other maybe not?
