Hi,
I've just started making the switch from LS2Edit to EFILive, and am currently running a LS3 via an E67 that has a '09 CTS-V OS in a swapped car.
I'm actually the original tuner, have all the cables & dongles and the .LS2 files used to program the ECM. I don't have a "stock" tune to reprogram it with, as the ECM was supplied by Carputing with the base of my current tune already installed!
I definitely didn't intentionally lock the ECM, and I can't find any lock/unlock options in LS2Edit.
I was really hoping to start from the LS2Edit tune already in the car because it's already running the car well, I just switched over because the other software is a bit clunky!
Unfortunately, EFILive can't read the ECM, because of whatever key is stored off by LS2Edit.
Has anybody managed to find where to extract the key from either an .LS2 file, or a datalog of the ECM<->Programmer communications LS2Prog can generate?
The existing ECM is a bit of a brick if I can't use it with EFILive, and it turns out my spare E67 isn't compatible with the '09 CTS-V OS. If I can avoid buying another E67, and starting from scratch, I'd love to.
