SCT and Tranny Learning Curve

[kingranchdude]

Hey guys,

How long does it take the transmission to figure things out after loading a new tune with the SCT? When I use my Extreme Street setting, it seems like the trans can't figure out what to do. I only ran it for about 15 miles before I bumped it down to regular street because of the erratic shifting. Anybody else had this issue?

I don't know about SCT but my edge takes about 50 to 100 miles. Bump for someone wiser.

Really, it should only be about 15-20 start to stop cycles. So if you drive around a kinda busy town, after 15 minutes or so, you should be good. You might need to call your tuner and get them to tweek your tranny information.

eric recommends 15 miles

Thanks guys. I guess I'll load it back up and ride around a little longer to see how it settles in. One other question though, what are the user changeable parameters that the programmer asks just before it loads the program? I think it asks to use the previous settings and that's what I use.

most people just leave everything stock...is what I've read. I only change the revs per mile so my speedo is correct.

One of the things I do when I load a tune is after I start the truck is put the truck in drive and then sit there and put it in drive, reverse, park, and go back and forth between the different positions a couple of time before I ever leave the driveway. I will then drive around but it generally does not take it long that is the beauty of the SCT.

You may not be running it hard enough initially for it to learn the tune. Load the tune with the truck warmed up already and then make a few hammer down runs right away for 0-60 at least and then 30-60. It should learn faster that way.

there are several answers to this. i've heard that "techically" it takes up to 200 miles. but depending on which tune i use, i've noticed it's anywhere from just a few blocks to almost instantaneously.
i usually do several runs from a dead stop up through the gears.
one at quarter throttle, one at half, one at 3/4, and another at full.

I talked to Bill at Dfuser and he said you should not hammer it right after loading a tune. He said it will learn the tune fine with normal driving. It makes sense.... Your tranny doesnt know what to do then you start pushing 400hp through it. Doesnt seem like it would be good for it.
