What is Checksum?
Software file integrity verification and checksum validation process.
Checksum is a mathematical verification value for ECU software file integrity. If not updated after calibration, the ECU may reject the file or the vehicle may not start.
In professional workflows, checksum verification before and after writing is a standard step. Checksum validation is also on the mandatory checklist in Prime Chiptuning file service.
