No response from PCM Hey Fellas,
I'm just a rookie at this programming stuff and I have two cars, one is a OBD-2 lt1 and the other is a OBD-1. I have the DST Tuner from Jet and tried to tune my OBD-2 car and somehow I think I killed the tuner, will not connect with the PCM at all, I have another LT1 obd-2 pcm that was working fine and wouldn't connect to that either, so I assumed it was my serial to usb converter and never got back at it since. Weird.
Now recently, since Summer, I've been trying to connect my laptop to the OBD-1 car. I had a cable from aldl cables that came with the car and it didn't seem to connect. So i went online and made the $10 FTDI aldl cable and still cannot get my laptop to connect to the PCM. All the ports are correct, the software is downloaded and installed and the little led's were blinking on the chip. I keep getting an " no response from the pcm" everytime. I have lost all hope trying to do this basic thing of connecting to my PCM. I have Winflash bought, Tunerpro installed and have the correct EE file and correct Bin.
I don't know what to do, next step would be building a bench programming cable?
Please help... Merry Christmas.

Did you make the 16 pin OBD1 cable? They are pinned differently. I just bought mine, works great. got mine from TunerCats.
The cars run and drive, so it's definitely something with your set up. Are you running the programs on the laptop in compatibility mode for Windows XP SP2? IIRC, you have to install them, from scratch, in compatibility mode (there's a special process to follow before the install to do it right). Under: Control Panel/ Programs/ Run programs made for previous verisons of Windows. That's how I did it on my Windows 7 stuff. If you have a newer verison I can't help there, sorry.

if you ever update to XP SP3 (the minimum requirement) you should try eehack (in my signature). it is much more verbose about what's going on. if you enable serial logging in the advanced tab, and send me a log of trying to datalog or flash read or whatever, i might be able to help you figure out what's going on. i'd recommend NOT trying to write/program until you have at least successfully read one bin so you know the serial interface is stable.

LOL, do you have another computer you could use? So far you have 2 cars with the same issue. And they both run and drive. So it's either the cables or the computer. Maybe try a different laptop and try again?

on the download page for my software please scroll down to 'required libraries'.
again, also requires XP SP3. SP2 wont work.
if you can't manage to drop some libraries in a folder you're doomed when it comes to actually tuning

I've been an LT1 edit/TTS user since 2000 and will dive into your stuff in the summer, but yes I do suck at computers. I use older computers for my car tuning as they have the serial cable for my ancient aldl connector.
