Reset the computer / PCM / CPU ?

[samiam]

On my new-to-me truck so far i've upgraded the air intake (well, slightly, at least) and upgraded exhaust. Also a new tranny. I've heard that giving the computer a reset will help by letting it re-learn the optimal settings. fact or fiction? if fact, how do you do it? unplug one or both batteries? or is there a fuse to simply pull for 15 minutes?
thanks.

the PCM/TCM will learn the stratagy over time weather you reset them or not....although they learn them faster if you reset them.

to reset them....disconnect the battery cables with the headlights on, when both are disconnected...put the positive and negative battery cables together (touching) for about 45 minutes then recconect everything (obviously dont connect one battery with the other cables still touching)...that will reset KAM (Keep alive memory)

Thanks Marc. I'd have never guessed it was so complex a process. You're not pulling my leg, are you?

what does doing this help? what are optimal settings its gonna relearn?

Mark, any recommendations on anything specific to do after resetting it? i.e. drive under 2K RPM on flat ground.... no load.

no....just drive it like your going to drive it normally

Marc, what's the significance of each step in this process? the lights on, connecting the battery cables...
