BMW via OBD on KESSV2

If you already own a KESSv2, you won’t need to buy anything! You just have to connect your tool, read the ID of the ECU and, thanks to the OBD Virtual Reading mode*, in a few seconds you’ll have at your disposal the related Original File. The Virtual Reading feature has never been so effective! Alientech currently has 16000 Original Files exclusively dedicated to the BMWs.

The new protocols 628 and 629 will allow you to read the ID, execute WRITE, perform the RECOVERY procedure and access the TOOL menu. Moreover, through the TOOL menu, you will be able to manually Backup and Restore the CAFD File (the CAFD File, or CAF-Datei, is the configuration file of the ECU): however, this operation is automatically performed during the writing procedure.

These new protocols, developed in collaboration with BMW as well as Mini Chiptuners, include the following advanced features:

• Automatic recognition of the Modified File. The protocol will unlock the ECU via OBD and will proceed with programming the whole Modified File.
• Recent modification updating. In case the ECU has been previously modified and new modifications are applied, the protocol will only write the latter. Programming will be much faster, since only a partial writing of the calibration zone is performed.
• Automatic checksum correction. The file downloaded through Virtual Reading is open, compatible with any remapping software and doesn’t require specific checksum correction procedures. The file is automatically corrected by KESSv2.
• File compatibility. In case the Original File wasn’t available in the VR Data Bank, it’s possible to read the whole file using K-TAG and write it using KESSv2.
• Writing recognition of an Original File. When rewriting the Original File, the protocol will recognize it and restore the ECU to factory setting, living thus no sign of the previous modifications.
