Interesting, maybe it has something to do with the PCM Seed? Did your tuner lock it? If so get the key and put it in the PCM seed spot when you go to read/flash it.

My tuner does not lock his tunes. In fact I asked him to upload the tune to a thumbdrive I had brought along and he said no need to do that because he knew that I have EFL Live and I could just download it myself.
I have tried all 4 USB ports and have loaded the latest USB drivers.
BTW I also have LSEdit and use the same laptop and can successfully download and upload LSEdit files to this PCM. I also am able to scan using EFLLive V6.
I don't have access to a stand alone workstation where I can take it my garage and attempt to read a file with it but as I recall when I tried this method the first time with the first cable I was able to successfully read the very first time with the workstation.
Nevertheless Paul did send me a new cable thinking it might be cable related. The reason I have not tried to do anything since I received the second cable is that the car has been down for mechanical repairs.
The tuner was using a Dell laptop and made a read the very first time. I made the mistake of not having him try to read the PCM with my cable. He is in St Louis and I am in Kansas City so not possible to try now. He tuned the car in KC. His response was that I had not selected the correct controller.
A similar thread said to wait for 15 seconds after connecting the cable and also to make sure the VIN was entered. When I selected get PCM information, it read all of that information from the PCM into every field on the form.
My laptop it a normal Satellite Toshiba about 2 years old with all of the latest drivers for XP.
I personnaly believe the issue is that there are certain laptops that just won't connect to the PCM (but only Boot Loader related) with EFLIVE and when someone figures out the issue with specific laptops then the bootloader issue will go away.
Can you connect to the pcm with the scanner?

That is possible, because uploading a bootloader to the PCM involves sending high speed, block mode data which is very different to all other normal scan tool operations. If you have access to a self powered USB hub you could try using that. Plug the hub into the PC, then plug FlashScan into the hub. Sometimes the data buffering and noise supression in the hub can eliminate problems.Originally Posted by dlandsvZ28

Before asking for help, please read this.
Thanks Paul
I'll try that - USB that is self powered.
My car is stored in Wichita, I live in KC so next trip to Wichita will give that a try. And I'll bring along a workstation too and plug it in. I am sure it will work too as it did before.
