  • Plug 'n Play kits are removed from the vehicle in minutes , returning the vehicle to stock tuning , without leaving a footprint of ever having been modified (a feature which reflash-tuning cannot match). The kit can then be used on a different vehicle. If the new vehicle has different bolt -on parts the kit can be reflashed to suit the new parts.


  • Jeep tire size & gear ratio correction now possible with Flux2 for all '07-> JK models. Ask for Jeep Firmware in the comments section of our shopping cart when ordering.

Installation Instructions for 3.6L Jeep JK

"Very clear, easy to follow instructions. Finally a worthwhile programmer for the 2012 JK, all I can say is WOW! Got my Flux2 display mounted in the glove box, ala 'stealth mode', ready for when I need it. This thing's mine now, you won't pry it from my cold dead hands!" Jason, CA.



"Took me 25 minutes to install, piece of cake. Just what my Jeep needed. I will add the Flux2 display soon & download some new maps when I install the Intake"  Moh.




"Plug 'n Play? Install it myself? Multiple maps? Doesn't affect warranty? A Display to match? WHERE HAVE YOU BEEN ALL MY LIFE!!!" Archie.



"Beware fellow Jeepers, there's wannabe trinkets out there! The Unichip is the most powerful tuning solution out there for our JK's, don't buy lesser junk, you will be disappointed!" Anthony.


"Couldn't wait any longer for the reflash guys to get their act together so I installed this. Definitely feel the power. Nice all round quality kit. I will get the display next month" Mike.
