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

Revainrating 3 out of 5

Works perfectly! 2013 Jeep Wrangler JK

Works great! If you are having trouble connecting your phone to the module, make sure Bluetooth and location services are turned on. Otherwise, you'll get a message that it's been disabled and the app needs to be restarted over and over again. Also, make sure to record the program only with the engine off and the ignition on, as indicated in the appendix. Attempting to write while driving, such as B. during tachometer calibration, will result in loss of tachometer function until you follow the correct writing procedure.

Pros
  • Trial for one year
Cons
  • Weight
