Used Hptuners all last summer, stored car and installed new parts. Now when trying to connect to scanner, it says, cable not found on 3 and 4 and then goes idle. I unplugged everything and then plugged it back in, tried again and it said Connected and gave me a voltage in the bottom corner, so I hit the play button to start scanning and then the "trying to reconnect" window comes up and thats it. It connected only the one time and now I cant get anything!

Any ideas?

Check the cigarette lighter fuse.

Confused. Why does that matter? Cigarette lighter has to work to power my Laptop since there is no battery in it.

Added info: At first I thought that I might have screwed up the wiring or something when I installed the 408 but I have a couple of other interfaces and software packages that I sometimes use and the one that I tried worked fine so.........................

Well, I guess it is not that Have you tried reinstalling the tuning software on to the laptop?

New update. I tried a different computer with the SAME cables. It connects to the scanner intermittently which is somewhat good. Problem is it wont read or write the VCM. WHen I try to write, it asks what file I want to use, then it starts working and comes back with a "download request timeout" error.

Anyone?

Nobody?

gameover

are you using a USB-serial adapter? if so what brand?

The issue is communications related:
1. bad serial cable (they can break from constant bending)
2. low quality USB-Serial adapter
3. slow PC, try reducing RX buffer size

this can also happen if your PC was just ok, but then installed a processor hungry virus scanning s/w etc.
4. bad connection on vehicle ODB2 connector (the pins can lose tension or come loose. rare, but it does happen).

Its a keyspan usa-19h. It worked fine all of last year. I guess it is possible that it may have a broken piece from bending, i guess thats possible. PC is not slow. 3ghz, plenty of ram, and no background apps.
