Also does your laptop have a physical serial port or are you using a USB to serial adapter?
Can you connect with the scanner?
Does your cigarette lighter work?

is it giving an error code when trying to connect with edit? is the error when doing a read or write? Has the PCM been tuned by someone else in the past (possibility of being locked?) What kind of car? (year, make)
May be an issue with the USB adapter, what brand is it? I don't recall what settings edit wants, but I would assume there'd be something in the help file?

Make sure drivers for the adapter are first installed, and then in LS1 Edit change the connection port to use, I think mine connects on COM 3 for my USB connection. I had your same problem till I tried all the different ports.

Go to LS1Program. Connect all cables. Click on the program_PCM tab. Select a program file. Go to the Log_comms tabs and select a file to save it as. When it gets done post the text file up here so we can see the error message.
If it really feel it is a com port problem then I would go into the Device manager in windows and see what settings are on this virtual serial port. Or try a laptop with a dedicated serial port.

HeavyWight: you need to provide some more info! (at least quote whom you're responding to!)
lots of posts here asking questions to help you, but your replys don't address most....
Given your last reply.... I would bet the radio shack USB adapter is to blame.... Radioshack and Belkin USB adapters seem to cause problems.....
if you can connect w/the scanner (as you said you can) but not via the edit tool... it's likely a problem with your USB to serial adapter... try different settings

Check your serial cable from the ls1edit adapter to the laptop. It's like a $5 cable... I had problems connecting in the past when I had ps1edit. Had a bad cable. If you wiggled it it would connect. Got a new one and was good to go.
