ECRI Allows you to update calibrations on 2007+ Jeep Wrangler and Gladiator. Just plug the ECRI device in your OBD port (2018+ Jeeps require a security bypass be plugged in as well) and open the ECRI app to get started. ECRI allows you to view and update calibrations like tire size, TPMS threshold, TPMS disable, axle gear ratio, transfer case gear ratio and more!
ECRI devices are reusable on multiple vehicles. Each vehicle requires an unlock, which can be purchased now or later in the ECRI app.
