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.
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.
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.
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.
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.
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.
