Review on Enhance Performance with ECRI Calibration Module for 2007-17 Jeep Wrangler JK - Unlock Features via in-App Purchase PER Vehicle by Ken Reed

Revainrating 5 out of 5

Works easy but follow the order to connect.

Works fine but you have to follow the order they don't show on their website. Turn the car to the working position without starting, connect the device and open the app. Otherwise no connection will be established. From now on, change whatever you want, then click Write. Put the tires up 2 inches, add 2 inches to the size he loaded and pinned it with my GPS and speedometer. In addition, the TPMs parameters were lowered due to the large tires, which also worked.

Pros
  • Absolute Legend
Cons
  • Hard to say
