Jeep Grand Cherokee PCM/ECU Recovery & Factory Stock Reflash Service

MoPower Calibrations provides professional mail-in PCM/ECU programming for supported Jeep Grand Cherokee applications. This service is for return-to-stock calibration work, software recovery, failed flash recovery, and corrupted or incorrect calibration recovery where the controller and application are supported.

Return Your Grand Cherokee PCM/ECU to Stock

If your Grand Cherokee is currently tuned, loaded with an unwanted aftermarket calibration, or needs a known factory-stock calibration, this service can restore a supported stock tune or perform a factory stock reflash.

Bricked PCM / Failed Flash Recovery

An interrupted flash, failed write, tuner error, or corrupted calibration can leave a PCM or ECU incomplete, unresponsive, or unable to run the vehicle correctly. For supported Jeep Grand Cherokee controllers, MoPower can attempt bench/mail-in programming recovery and stock file recovery.

PCM/ECU No Communication After Flashing

No communication with the PCM, lost communication with the ECU, scan tool communication problems after flashing, or a no-start after failed programming can have more than one cause. Wiring, power, grounds, CAN/network faults, physical controller failure, or other vehicle problems can create similar symptoms. This service addresses supported programming and software-recovery cases only.

Corrupted or Incorrect Calibration

This service can help when a compatible controller has an incorrect calibration, modified calibration, corrupted calibration, unsuccessful tuning write, or incorrect software loaded for the application.

Mail-In PCM/ECU Programming

This is a mail-in service. After ordering, ship your ECU/PCM to MoPower and include your full name, return shipping address, and vehicle VIN number in the box. Missing information can delay service. Return shipping is charged with the order; shipping the ECU/PCM to MoPower is the customer responsibility.
