You cant have the scan tool and try to flash at the same time...disconnect from the scan tool and close it. Then reopen the file and full flash it.

No, I didn't try to flash it while I was connected, I was just saying, the scantool worked ok, but it won't flash.

Ah gotcha, hmmm interesting. Have you rebooted the pc, connected the V2 to your laptop, then to the car, then opened up the tune file? Ive found on some 02-05 TBs they are very picky to the order everything is connected. Even sometimes my 02 is picky. The 08 is much more forgiving, no idea why.

I got it to take it, what a nightmare, I did a full reflash and it got hung up half way through, it wouldn't start or take a flash after that, I took the neg terminal off and touched it to the pos terminal, also I had to remove the fuse for the tailgate module?? It worked but now I guess I have to have the crankshaft postion sensor re-learned??? Can I do it with EFI or do I need the Tech2??

Interesting, you can do a CASE with EFILive but thats interesting it needs to be done. Not normally something that ever gets overwritten by a full flash, VIN and CASE usually stay untouched.

Use the scan tool, if you cant connect to DVTs using the P12 try using E40 stuff.

I reset it with the Tech 2 yesterday, its good now. We noticed in his original OS the oil change light never came on, with the updated OS it has a change oil light in the cluster now.
