Reviews for AEV 30406007AG ProCal Module for 07-18 Jeep Wrangler JK

Worked as expected.

Works as advertised. Fixed speedometer after adding 35’s. My rubicon was assembled in Canada, so I was finally able to turn the lights off.

performs as prescribed

I haven’t used it yet but I guess it’s ok the mechanic used it due to changing the anti swaybar system

Performed as advertised when reprogrammed my speedometer and TMP sensors.

This is an awesome tool. I could not get the warning light for my tires to go out. I’ve tried every possible thing people were suggesting and nothing worked. I was going on two years with that damn light being on. At one point I was tempted to just put electrical tape over the light so that I wouldn’t have to look at it. I’m so glad someone suggested this thing!

Plugged this in my 2014 Rubicon with 35 inch tires and speedometer is perfect in less than 10 minutes. Perfect for making things easy and quick when modifying tire size, etc.

Works great and easy to use.

Awesome must have product for any modified jeep

Simple effective and affordable. Like others said, a must if you plan to run bigger tires!
