Ugh but one little issue.
I have got a 2013 JKUR built in May of that year.
When I switched over to bigger tires I did not want to even mess with the TMPS. I wanted the ability to air down, to run lower pressures and not have to swap the TPMS sensors out of the Rubicon rims.
So I got the Procal. At first it worked great. Turned off the TPMS by setting it to the "Disabling" mode. Never saw a light or a warning or anything. Perfect.
Then went in and had some warranty work done and had my back up camera enabled. They had to upload the latest program (whatever its called) from Chrysler.
When I got the Jeep back it was as if I had never used the Procal. My shift points were off, my daytime running lights were not on and the TPMS was going off.
Brought her home and reloaded everything with the Procal.
Now no matter what, every time I get in and start it up the TPMS display comes on in my EVIC and I have to press Menu once on the steering wheel to get back to temp. and compass heading. Never get a chime or any other lights, just the display showing all four tires at 0 and the message to "Check TPMS"
Keep meaning to call AEV but too busy. (or lazy)
Side note; If you do exactly what they tell you and enter the date right the Procal will set your speedo correction to within .01-.03 of actual MPH. Checked with a Garmin GPS.
(Not the one in the dash)
I think the difference is a few things one being tire pressure as that changes the actual tire height, the other being that it is very hard to tell exactly if you are going 70 or 70.01 on our gauges.
