New AT Protocol Release!
🎁 Wrapping up the year with a long-awaited release!
ZF 6HP TCUs, used in BMW E-Series (and Alpina) automatic gearboxes, are now supported with Normal Read (NR) via OBD using your AT Tool.
⚙️ Protocol status: This release is available as an Open BETA. It is immediately accessible to all users, as the protocol has proven to be stable and fully operational.
That said, since not every variant could be tested in-house, your feedback will be highly valuable to help us confirm full coverage.
A little end-of-year gift for all our users. 🎉
