Awhile back there was a very detailed thread on EFILive site on how to gain access to a locked PCM. The thread was removed at the request of tuning shops and resellers. Did anyone happen to copy that information? I would like to be able unlock pcms of customers. I believe I have the required hardware with benchtop flashing cable and an avt 852. I have been playing with couple free pieces of software, not very special. HPTuners has some very old posts from when they were devopling their software with all the commands to get the info I want. I think I need a good communication program, a means of setting up the software to try each of the 65536 keys, and a means of recognizing when it has found the right one. Oh yeah, and a clue how to accomplish this!
Planethax developed some software for use with the elm327, I have yet to make it succesfully work, but this is what I am after. Does not have to be that fancy, just do the job.
