Identification: The application queries the vehicle’s VIN (Vehicle Identification Number) via the J2534 device.
Validation: The VIN is sent to the Chrysler server to verify eligibility and retrieve the list of available calibrations.
Comparison: The software compares the current ECU calibration string against the latest available version on the server.
Download: The user downloads the calibration file. Crucially, this is a "smart download" if supported, retrieving only the differences (delta files) to save bandwidth, or a full binary image.
Reprogramming: This is the critical phase. The application puts the ECU into "bootloader" mode. It erases the old flash memory and writes the new binary.
Verification: A checksum is performed to ensure data integrity.
