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

Got what I paid for.

The AEV procal module works great just as advertised and I was very surprised at just how easy and fast it is to adjust and set calibrations on the Jeep. I used it to adjust for bigger tires and lower tire pressure. Speedo is right on and Tpms system still works great with the new settings.

product does remarkable job and simple, changed tire size and tpms setting in less than 5 minutes

Works as advertised. Super fast and easy.

What can I say it was just as easy as advertised. It took just a few minutes and made a big difference in shift timing and gas mileage. Set the tpms sensors, and adjusted for larger tires. Definitely a wise purchase.!

Easy to use and clear instructions. After lifting my jeep 3" with the additions of 35" tires I was able to re-calibrate speedometer including auto trans.

This works just as expected. I have changed both tire size and pressure sensor settings, and both worked just fine.

I have a 6 inch lift with 33’s on my 2017 jeep jk. Bought this to fix my shifting issues and it sure did. Jeep shifts smoother and runs great. Simple and easy to use.

Great product, easy to use, does more than others. I'd recommend not keeping it in your glovebox. (mine was stolen)

Easy to use, can carry it in Glove Box.
