Question about how this computer "learns"

[Elwood P Dowd]

Ok so I've got a 2000 F350 with the 7.3 and 127,000 miles. I remember when I took this truck for a test drive when I would really get into it and before the turbo really spooled up I was see a pretty good amount of black smoke. Nothing alarming just typical diesel stuff. My Question is now that I've had it a few months I dont see that any more. Did the computer just "learn" that my foot is heavier than the previous owners or should I be getting this checked out. The truck seems to run fine but now when I really get into it I just see nothing or if anything my exhaust has a slight grey look to it if I remember right. I dont have any gauges yet so I cant check boost or exhaust temps.

Its hard to say if some thing is wrong with out gauges to check every thing but it also could be some thing as simple as the truck sat for a while and you have just finally blown all the soot out of it. If all your factory gauges are reading normal and the truck is running normal, I wouldn't worry about it untill you get some more gauges and see whats really going on.

Thats about what I figured. Thanks

a stock truck honestly doesnt smoke much if at all. so thats normal..

Our PCM's have no adaptive stradigys. They dont "learn"

Is it cold where you live?...my turbo seems to light faster when the air is cold and the air is dense, which makes my truck smoke a little less than when its hot out...also, we've got a '99 PSD farm truck, and when my dad takes it for a while and babies it, it smokes a good bit when I get in it drive and run it hard, I guess it just builds up in there and waits for me to blow it out, it'll smoke good for a day or 2 then clears up with me driving it

They do learn somewhat. Mainly in the first 10 miles or so I think after resetting it. I bet there was just a bunch of junk in there. Change oil, air and fuel filters. Bet something was clogged up.
