Just had traildash installed on my 2012 jk sport, also k&n cai intake & borla exhaust. WOW!!! what a difference
This thing is way cool, easy to use, does a bunch of stuff. Like clear codes, drag strip setting, different performance
and OFFroad and towing settings etc. etc. I know it's more money but IMO it's well worth it.

 

Is there an obvious way to tell for either of these 2 when buying used if it is locked to a previous VIN?

Only reason I'm asking is I may be buying a used flashcal locally from someone who bought it thinking it would work for a 08' Grand Cherokee. They plugged it in but Flashcal didn't recognize it.

 

You will know if you plug it in and try and reprogram and it wont. I would say meet in a parking lot and try it. AEV lets you know if it works by honking the horn X number of times depending on what you are doing. Ie speedo 2X. resetting it 3X

 

Just spend the extra coin and get the superchips trail dash if u have the Rubicon. It's SOOOO worth it!



U can control ur sway bar, lockers and tpms Plus tons of other things

 

Ok...that looks sweet....but doesn't look like they have released for 2015 models yet.....might be worth waiting though. hioefully will come out soon...or heck...maybe they just haven't updated there website yet.
