The flashpaq 3865 is your best bet and will work for the 1998-2003 5.9L; +46.9HP and +59.4 lb-ft torque.

You do not need to have the tuner connected all the time. Cannot change tunes on the fly as it requires key cycles. You can change from one tune to another provided you have the correct octane in the tank but you have to stop to do it.

They do not offer a mounting system but you can get a phone mount if you so choose. Remember though these tuners have a tendency to "walk" if left in a noticeable position.

You will want an authorized vendor, I got mine at StreetSideAuto.com but, you can do a google search for "flashpaq 3865" to find other vendors. Can also purchase directly from Superchips.

 

Thanks for the quick reply! Ok thats awesome. So lets say i wanted to switch tuning from economy to 87 performance at a red light. Is that possible? or does it take time for the tuning to switch over/have to turn my vehicle off?

Ill be ordering one tonite!

 

Thanks for the help so far bigpappa

i reset the pcm and did the procedure with the gas pedal on and off, seems to be better.

I purchased my tuner on ebay...
You were saying that in the shift schedule there is stock and superchips, mine has 1u2u2p so and so forth
is it posible the previous owne purchased the trans upgrade, and if so would it stay in the tuner?

 

no, in order to switch tunes you must stop and turn your key on/off multiple time (tuner will guide you) and run the required Octane rated Gas (93,91, or 87)

 

When you select Shift Schedule, and then Up-Shifts (or Down-Shifts), do you see Superchips, User and Stock or just Superchips and Stock? Can you change any of the set points; for example, 1Up?

Yes it is possible that the previous owner purchased the Advanced Trans Upgrade however, that software is "supposed" to be VIN specific. That is, it is not transferable to another vehicle. Therefore, if your tuner shows "User" as an option for Up-Shifts and Down-Shifts, I recommend calling SC 1-888-227-2447 to let them know as this could be causing the problems you're seeing.

Also, if your tuner has the User option, I strongly recommend you change both Up-shifts and Down-shifts to either Stock or Superchips until this gets straightened out. Do the same for Torque Management.

Good luck and keep us posted on your findings.

 

I have the same issue when slowing down. almost get to a stop and the engine speed jumps up about 300rpm.. its kind of annoying.

 

Quick question, prolly already answered but... Can I use my tuner to run check codes on any other vehicle with an obd2 port, or only on my truck?

 

Yup, can read any vehicles' codes.

 

question...i have a SC 3815... my stepson has a 2010 ram slt gas hemi ..can he use the 3815 to tune his truck? he has limited budget so i thought i'd give it to him save him a few bucks

 

No, sorry. The 3815 will not support the Gen IV trucks ('09+). He'll need a 3865 for that.
