Thats why i am asking, my VE table looks like the rocky mountains, But one press on the smoothing button makes it look ok. Of course iŽm going to keep scanning and tuning the VE table... Just wondering if anyone else is using it? And if not then why not?
if you have your tune close, the poly smoothing tends to throw it off. It's normal for the VE table to be rocky while you are tuning. As you collect more data, the table should take shape and start to smooth itself.
All I know is that every time I use the polynomial smoothing, it leans the car out all over the VE table. I recommend hand smoothing or just collecting more data like TAQuickness said.

when i was first starting my SD tune, I would polynomial it w/4 decimal precision once or twice to smooth it out , but once I had a majority of the table insynch i would only hand smooth

Same method here. I use it the 1st and 3rd run...Just make sure it is set to 4 decimal places. I then go back and hand smooth on the 4th run...By then I pretty much have the table dialed in.

I dont use smoothing at all...
my car responded sluggish when I smoothed anything...
I left mine as is and all my LTFT's are -1,0,1
and thats still the same after 2 months later...
If the car is going to adjust the LTFT's to get it at 0 then what is the point of making it look pretty...
even if you smooth it out...your car adjusts so that it gets 0...
when you smooth...lestr say you get a -4...
teh car is going to be at -4...not the value in your table....so its going to have those ridges and un smoothed spots in its LTFT memory...
why waste time...
get it dead on and you computer will not have to add or subtract to that value to get what it wants anyways...
its like teh time travel theory...a bunch of BS... you cant travel in time.... you can only get ahead of when the light/sound reaches you so that it gets there later....
same principal on LTFT... the computer is going to add ro subtract anyways...so why are you trying to tell it to travel in time
sorry for the rant..
