They cannot say only LS2edit locks the PCM because there is no other tuner product out there !

Sure its possible that carputing felt they got screwed in other tuner vendors backward engineering LS1edit uses PCM flashes that had been done with LS1edit or decided no to give up how they found what GM security code was by locking others out.

Since I do not have LS2edit I do not know if its fact of fiction that other tuner vendors are saying just so you wait until their product gets out and is scaring people not to use LS2edit.

Until I see it the history is the others are lying and LS2edit does not lock but has a feature that would allow the tuner to lock the PCM which is nothing new it can be done with C5s.
Many of those slim tuners want and have locked people out of their own car's PCM, not so you see what they did but to hide what they did wrong or did not even tune correctly.
