- Bosch EDC17/Campaigns: Improved support for Bosch EDC17 ECUs, specifically resolving issues with read/write operations on certain "Campaign" versions found in VAG group vehicles.
- Continental/Siemens: Improved reading capabilities for Siemens/Continental ECUs, which are notoriously difficult to read via OBD.
- Denso: Expanded support for Denso ECUs found in Asian vehicles (Toyota, Suzuki) and heavy-duty trucks (Iveco).
- Bosch Motorsport: Added protocols for high-performance Motorsport ECUs.
Checksum Correction Fails
While Kess 5.030 auto-corrects checksums for many ECUs, it fails for some Delphi and Denso units. Solution: Manually correct using WinOLS or ECM Titanium before writing. Never write a file with a bad checksum; it will brick the ECU. Kess 5.030
