Identification looks like this:

VIN number: 1C4RJFCM5EC531366

Part number: 05150767AC

Serial number: T00YF1234H1514

Software version: 68270626AE

Calibration file: MAW4J4W270XX02H

CVN number: EDD3BF04

To see the CVN, you need to hold down the Shift key.

Reading: EDC17CP27 – via the OBD port, can be done with the engine running. For EDC17C49/C79, try reading in the vehicle; if that doesn’t work (and if there’s a “gateway”), direct connection to the ECU port is required. Reading time is up to 10 minutes. After reading, you’ll get a file that also contains the Bosch number: 10SW002641_68270626AE_MAW4J4W270XX02H-20181203-002526.bin

The pinout for EDC17C49/C79 can be found on the evc.de website.

Second option:

Writing: Only calibrations are written, so you either modify the one that was read or find a file by software version or calibration file. Files read in BSL (boot mode) are suitable. In case of a communication interruption, simply restart the writing process; you can turn off the ignition if needed. IMPORTANT: If you get a P0633 error after writing, it’s likely that the tuner forgot (or doesn’t know how) to mask this error. Some tools, like K-Tag, perform this automatically, and many users may not realize this.
