bFlash now supports the Porsche / Audi ASG1 over OBD, on cars such as the Porsche Taycan and Audi e-tron GT.

The new protocol uses OBD Virtual Read (VR) to read the ECU, and then allows a full flash*, including ASW. You aren’t limited to calibration changes: you can write the complete software, straight through the OBD port.

And in it’s bFlash fashion: it’s quick too 😉. The first flash takes about 4 min 30, and each flash after that takes about 1 minute.

*Full flash can be obtained by contacting our support team.We are excited to announce expanded coverage for the Bosch DQ381 TCU, found in Volkswagen Group vehicles from 2021+ onwards.
