So, I bought this and decided to just use it for the tire size adjustment until I know that Superchips figures out how to program the 2014's. I first updated it when I received it and then about a week later hooked it up to the jeep. It read the stock file and gave me a message to update the software. When I connected and did another update it told me that my vehicle wasn't supported and to send the message to Superchips and they would contact me when they updated the tune. I would think by now they would have the 2014's figured out, especially with some of the trouble I have been reading about with the dead jeeps. I will update when I hear from them. I'm just glad I didn't try to use one of the tunes. Thank you to those that have tried this before me and sorry for your troubles.

 

My rubi was built in 1/2014 and I was able to successfully tune my vehicle (87 octane) with the new flashpaq 3872.

However, I'm unable to set my TPMS to 0. The lowest setting I was able to set was 22 on the flashpaq, yet oddly it shows 29 as the setting on the EVIC. I'm assuming they haven't worked out all the kinks yet for the 2014

 

No issues with my 14 JKUR!! Have ran both the 91 and 87 Performance tune and was able to adjust for tire size and my speedo is near perfect...I just can decide which tune is best for fuel economy with my 3.5" lift and 35" toyo MTs

 

Superchips web site and download the off road tpms setting to the tuner. You can then turn the tpms to off.

 

I got an email from superchips today saying that their records show that your vehicle was not supported by your programmer. An update has been posted and your vehicle is now supported. I updated the tuner and I was able to change my tire size. I'm still a little nervous to try to change the tune. I may wait until a day I'm off during the week, incase I have problems.
