Kefico CPGDSH2.2x.x / CPEGD2.20.x Series

These ECUs are powered by the Infineon Tricore TC1782 MCU and feature 2.5 MB of internal flash memory.

• CAN-bus Access (FID: 251):

  • Functionality: Allows reading the full flash and writing the calibration area through the CAN-bus.

  • Checksums: Automatic checksum correction is provided.

  • Supported ECUs: Includes CPEGD2.20.1, CPEGD2.20.2, CPEGD2.20.3, CPEGD2.20.4, CPGDSH2.26.1, and CPGDSH2.24.4.

• BSL-mode Access (FID: 253):

  • Functionality: Allows both reading and writing the full flash with checksum correction in Boot Strap Loader (BSL) mode.

Kefico CPGPSH2.14.1 / CPEGP2.10.1 Series

These ECUs utilize the Infineon Tricore TC1728 MCU with 1.5 MB of internal flash memory.

• CAN-bus Access (FID: 303):

  • Functionality: Supports reading the full flash and writing the calibration area via CAN-bus.

  • Safety: Features automatic checksum correction.

• BSL-mode Access (FID: 304):

  • Functionality: Supports full flash reading and writing with checksum correction specifically for BSL-mode operations.

Important Implementation Notes

• Connection Constraints: While these modules are designed for CAN-bus operations, certain vehicle configurations may not permit communication via the standard OBD2 plug. In these instances, a bench connection must be used for reading and writing.

• Tool Purpose: BitBox is used for the transfer of data (reading/writing). If you intend to modify the parameters within these files, you would typically use an editor like BitEdit.
