sorry i cant help you but im curious what do you mean when he locked your pcm
wow.....pretty low if you ask me i don't mean to offend you but why would he do such a thing did you have some motor work done or somethingI was told that this was done to prevent others from seeing how he did the tables and such. I am not computer literate to explain what he did to lock it....only that I am told that if I want to make fine adjustments or simple changes to fan settings, etc, only he can do it....no one can access the program.
Password protected, I would presume.
What does a new one of these things cost anyways? That way I can start from scratch again, and if I get into trouble, I can always put the other (locked) computer back on.
