Good question, I too have this same issue with a 1999 crew cab (5.7L vortec) I need to set the timing and everytime I do it manually the computer over rides my settings. I have heard about this mysterious timing wire that needs to be disconnected to set the timing and then reconnected once the timing is set and the computer can record the new setting. The Brown/black wire has been scene under the passenger side carpet, behind the glove box and next to the relay center. Unfortunately, This 1999 doesn't seem to be the norm. Good Luck
