AI summary
Firmware Specification & Technical Report: Version 3.5
1. General Overview & Identification
Target Hardware Platform: SE8M5PS (ECU/TCU Controller Family)
Software Version: v3.5.3.5 (Internal revision counters: 00 03 00 05 03 05)
Release Identifier (ASCII): SE08-2.3D11A06
Build / Release Date: Encoded as 2904012 (April 29)
Binary Integrity: Fully verified against redundant production binaries (File 1 and File 4 show 100% bit-for-bit parity).
2. Memory Layout & Map Architecture (0x0DFE00 – 0x0DFEB0)
Memory Bank Allocation: Calibration map tables are mapped to the higher memory bank 0xFF (prefixed with opcode/bank descriptor 79 FF).
Vector Table Offsets:
Base map pointer begins at address 0xFF0608.
Subsequent map vectors increment dynamically across the table (e.g., 0xFF06A0, 0xFF073C, 0xFF0874, up to 0xFF0CF0).
Table Alignment: Each 16-bit pointer entry is 16-byte aligned using the standard padding byte 0x44 (and trailing 0xFF boundaries).
Relative Geometry: Preserves standard map spacing (+0x98 / +0x9C bytes between consecutive map blocks).
3. Metadata & Checksum Block (0x0DFFD0 – 0x0DFFFF)
Descriptor Header: Resides at 0x0DFFD0, holding the active version string 32 39 30 34... along with the core project ASCII identifier SE8M5PS.
Block Integrity / CRC: Address 0x0DFFF0 contains the release-specific calibration checksum and verification block, properly terminated with the synchronization word AA 55.
4. Cryptographic Signature & Configuration Area (0x140000 – 0x1402FF)
Release Signature Header (0x140000 – 0x14003F):
Payload Hash / Digital Signature: 59 0C 4D 92 86 D4 12... (Offset 0x140000).
Initialization Vector / Crypto Header: 13 B9 31 DD ED 49 C3... (Offset 0x140010).
Explicit Release String: Plaintext ASCII identifier SE08-2.3D11A06 located at offsets 0x140020 – 0x140037.
Calibration & NVRAM Initialization (0x140200 – 0x1402FF):
Begins with the valid sync word 0xA55A and format version flag 0x0001.
Contains a 240-byte zero-padded (0x00) memory space reserved for dynamic runtime parameters, adaptation data, and DTC/NVRAM storage.
File read by custom made k-line dumper software.

Based on the binary structures, hexadecimal layouts, metadata headers, and firmware lineage analyzed across the dumps, here is a comprehensive technical summary of this ECU:
ECU Technical Profile & Architecture Summary
1. Identification & Platform Details
Manufacturer / Hardware Family: Delphi SE08 (referenced internally by the platform tag SE8M5PS).
Software Version: v3.5.3.5 (internal revision counter sequence: 00 03 00 05 03 05).
Full Part / Calibration Number: SE08-2.0SPMB00043D11A0647 (ASCII decoded at offsets 0x140020 – 0x14003F).
Build / Release Date: Encoded as 2904012 (April 29 release).
2. Memory Organization & Flash Layout
Map Table Vector Block (0x0DFE00 – 0x0DFEB0):
Contains a pointer lookup table referencing the physical locations of calibration maps.
In earlier revisions (v2.0, v3.1), maps resided in flash bank 0xFE (base address 0xFED750).
In the v3.5 revision, expanding code size pushed calibration tables into higher bank 0xFF (starting at 0xFF0608 with opcode/bank prefix 79 FF).
The internal layout and relative geometry of the calibration maps remain consistent (+0x98 and +0x9C byte spacing between vectors), aligned to 16-byte boundaries with 0x44 padding.
Metadata & Checksum Header (0x0DFFD0 – 0x0DFFFF):
Stores hardware tags, build counters, and calibration CRCs.
Uses the standard embedded synchronization/termination marker AA 55 at 0x0DFFF6.
3. Security, Authentication & NVRAM (0x140000 – 0x1402FF)
Cryptographic Release Block (0x140000 – 0x14003F):
Payload Signature / Hash: 59 0C 4D 92 86 D4 12 5F 9A 40 7B 1B 0A 8F 1D AE (offset 0x140000).
Initialization Vector (IV) / Crypto Key: 13 B9 31 DD ED 49 C3 F5 F3 42 83 70 91 AC 40 CB (offset 0x140010).
Explicit Model String: Contains cleartext ASCII string SE08-2.0SPMB00043D11A0647.
Calibration / Adaptation Descriptor (0x140200 – 0x1402FF):
Sits at fixed offset 0x140200, beginning with standard sync magic word 0xA55A and format version flag 0x0001.
Contains a 240-byte zero-initialized sector (0x00) dedicated to runtime NVRAM adaptation buffers, fault code logging (DTCs), and vehicle configuration data.
