Do you have to disconnect both battery cables to reset the PCM and if so for how long?

I have only disconnected the negative terminal, but ive now heard you have to disconnect both?

 

Just the negative cable will do it. Leave it unhooked for about 10 mins. and that will be plenty. Why do you feel you need to reset the PCM?

I am just wondering if the adaptive learning that the PCU does is somehow affecting my tune. But if disconnecting the negative for 10 minutes or so is enough I have done that already and it didnt fix my problem.

The source of my problem is in this thread

I have read thru the your other thread and if I was experiencing your problem I would I would put the stock intake system back on and your stock tune for a week or so to see if the issue went away. This is about a 30 min. total job and may answer most of your questions. If it still is doing it then you are ready to head to the dealer.

I was told you could turn the lights on after the disconnect and it would kill the back up batttery so this is what I do. Would you please come back and tell us how you correctecd the problem. I might have the same problem later.

 

as soon as I get my predator back I will be flashing it back to stock and putting back on the stock airbox to see if it still does it. I will keep you guys updated on the progress of this in my other thread.
