A Master reads unencrypted files; a Slave exchanges encrypted files with one designated Master. The choice therefore defines both the technical workflow and the calibration team behind the partner.
How a Slave workflow operates
The local professional identifies, diagnoses, reads and writes the vehicle. The Master decrypts, calibrates and returns the encrypted file. This allows each party to focus on its core work.
Choosing responsibly
Compare support, turnaround, validation, pricing framework and exit conditions—not only file cost. A Master tool provides freedom, but also requires calibration software, knowledge and validation capacity.
Frequently asked questions
Can a Slave use any file provider?
No. Its encrypted files can only be processed by its designated Master.
