Jeep Wrangler JL, Jeep Gladiator JT 2018-newer Calibration FAQs

Additional Help


Device Not Connecting

  • Bluetooth needs to be enabled on the device and for the app (iOS & Android). Android: ECRI needs location permissions to scan for the device.
  • If "ECRI" on the device is lit red, it is discoverable and awaiting connection.
  • If "ECRI" on the device is lit green, the app is connected.
  • If the device is not lit, unplug and plug back in.
  • The device powers off after 30 seconds without connection. This prevents excess battery drain and provides a layer of security to prevent unintended access to your vehicle.

Speedometer Not Accurate After Calibration

  • The tire size entered is the size on the sidewall and it needs to be reduced (typically 1") to account for tire "squish" from weight of vehicle.
  • The settings are not taking effect (see support item below about this).

Settings Not Taking Effect

  • JL/JT Models can require a longer "off" period after programming. If this is happening, do the following after programming:
    • Turn ignition off
    • Open the driver door
    • Exit the vehicle with the keyfob
    • Close the driver door
    • Wait at least 5 minutes to ensure all modules power down
  • This ensures all modules power down. When modules power back up, they check with other modules on the vehicle for new settings and self-update at that time.
