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

Works flawlessly. I don't think they could have made it any easier if they tried. 10/10 would buy again in a heartbeat.

took longer to get out of the box than it did to program for larger tires

Excellent, had a re-gear in the last 30-days and having was vital for OBD reset.

Works exactly as described. I was able to reconfigure wheels sizes to fix speedometer being off after lift kit, larger wheels, and 6.4L Hemi swap in 2016 Jeep Wrangler Rubicon.

Must have if you've change you tires for bigger.

Used it to turn off TPMS and set tire size for larger tires, super easy to use!

Just have to say how pleased I am with the AEV Procal module. It only took 2 minutes to calibrate my speedometer and gained about 6 more mpg. The shifting is much smoother and doesn’t downshift at every small hill. Also changed the TPMS low tire light to come on at 24 psi. Highly recommend!

This product is unbeliveable. Its easy to use and it is super accuate. I needed this to shut off my TPMS and to change my tire diameter. It took me longer to read the manual then it did for the actual programming to happen

Spedometer calibration alone makes it a must have.

Great product! Super easy to use. I immediately noticed a difference in the performance and shifting of my Jeep. Prior to using this, I installed slightly larger tires. For about a year I've put up with my jeep not shifting correctly. Too low of gear when it needed to be higher, to high of a gear when driving uphill. Instant fix, totally recommended!!!
