Just got my new 3870 superchips today and did the computer updates. Plugged it in and it saved files but would not tune, said it needed to be updated. When I plugged back into the computer it said there was no programing for my vehicle (2012 jkur auto). Asked for my email and said I would get a reply in 2 weeks. Anyone else having problems with this??

 

Not sure whats going on, but i've heard of similar stories. Tuned my 2011 with no issues.

 

There's a few updates. Update spark to the latest version and restart your computer. Mine worked fine after that, I was able to download all the tunes. The only thing I'm not happy with is the TPMS. It says you can disable it, when I tried the yellow indicator goes away but I still get a toms warning check message on the left side and shows all the tires at 0.

 

I ran the 87 tune, definitely noticeable improvement in the 3-4k range. I adjusted the tire size and checked my speedometer against my gps speed for the best accuracy.

 

How did it work for the 2011?

 

Works fine for my 2012. Fresh spark install and fresh update on the tuner.

 

it updated and tuned on my 2012. works just fine

 

I have the FlashCal and upgraded to the FlashPaq tuner (firmware upgrade). I have mine set to tow haul and you can tell the diff. I get less down shifts on the way to work now.
I'm running 315's for tires and had to calibrate the tires to 34.0in to get the speedo right. At 66mph i'm really running 65.5 (GPS), thats close enough for me.
I didn't turn my tpms off but i did lower it to 5lbs and have not had any issues.
Does anyone know how the locker function works? Does turning it on just allow me to use a locker in 4hi or does it lock the locker?

 

So you can now upgrade the flashcal to a flashpaq? If so how much does it cost? I've been waiting on this capability. I just updated to the spark software last week but didn't see this option at that time.
