Best option for corrections in my opinion. Love the upgraded software allowing auto start stop feature to be disabled.

You can change several settings. I turn off tps when off roading turn back on for street drive. Kinda nice

Have a Flashcal for my JLUR with the 2.0t and it works great, however when my 4WP person tried to set a new one up on my Wrangler 392 this weekend it would not work. All we were trying to do was a speedo correction for new tires. He tried updating the unit and everything, no go. Just something to be aware of if you have a 392.

Save your money! Just don’t do it! So disappointing

Purchased this for three specific reasons that I was told it would fix with my 2019 JLU Rubicon 2.0 Turbo with LED package. 1)Adjust for new 35" tires. 2) Turn off the "auto on/off" feature so that it stays off. 3) Turn off the "tail light out" notification due to aftermarket LED tail lights. The unit will adjust for the 35" tire size but it will not disable the auto on/off between uses without also disconnecting the hood alarm and the system fault warning light can't be turned off. Not much function for the price. I spoke with 4WP and Superchips customer service and they were little to no help. So, who knows? But, as for me, I would recommend a different device and I probably won't go back to 4WP.
