Is it worth it for me to buy a 3815 tuner used if I can find one for a decent price, or should I hold out for a 3825 so I can get the new trans program when it comes out? Will the new program support a 2002 Ram 1500 4.7L?

 

From what I can understand I believe the new PT and TM is for 04+ . . . this could, but doubt it, be wrong.

 

2002 won't be supported. 04-08, 09.

A 3815 will work fine.

That's the story of my life. *lol* Always just slightly behind the curve.

 

03 r gettin the **** end of the stick too unless they can take a challenge and help us hemi owners get what everyone else gettin. Keep hopin they will get bored and hook us up!

 

I can pick up a used 3815 locally for $250, but I may just hold out for a cheaper one online. Now here's my stupid question for the day, this 3815 says it's for 2004-2008 5.7L Hemi, but if I update it it will work on my 2002 4.7L correct?

 

SC added yet another great new feature to the trans options- arrows showing the stock shift points as well as the relationship of your adjustments to stock. This feature will significantly ease the learning curve for new users!

If you guys pay attention to where those arrows are, you can learn a lot about how your trans is set up. Specifically, what you do like vs don't like, and then tune from there.

What I found most interesting, although not surprising, is how non linear the stock trans shifting/programming actually is. That is why sometimes you have to stab the pedal hard to force a downshift, and other times they happen unexpectedly. It's almost as if they just randomly programed the shift points.

Curiously, some of my downshifts were actually less sensitive than stock. My first inclination was to change them in relation to the stock tuning. However, it occured to me that the last thing I want to do is emulate the stock schedule by simply making it more aggressive, yet just as unpredictable.

Whatever you guys do for programming, I recommend you put it on paper, maybe even graph it if you feel nerdy enough. This stuff makes a lot more sense when you can see all of the shifts together, as opposed to one gear/tp% at a time.

A smooth progressive schedule makes for a very natural feel, vs the erratic, unpredictable feel of the stock tune.

 

When u update do u hav to return to stock b4 updating for it to work.

 

I never do.

 

once all the testing is done and the various versions are released, it would be neat for the testers to release their settings as a sort of "playlist" for us novices to start from and play around with.
