I’m a Jaguar enthusiast with a particular interest in preserving and modifying the XK8/XKR cars (X100 model).

Recent projects have included:

  • Enabling axle ratio changes by modifying canbus wheel speed messages between the TCM and ECU, using Arduino based module
  • Analyzing the AJ27 ECU firmware using Ghidra:
    • Ghidra loader for IDS AJ27 firmware files
    • Ghidra processor module for 68HC16
    • Ghidra analyzers to find tables and perform stack analysis
    • Ghidra scripts to assist in markup
  • Motorola BDM application for flash code and configuration data extraction, using Arduino based module
  • Writing a benchtop application for AJ27 ECU:
    • flash code extraction
    • reflashing
    • eprom persistent data extraction and overwrite (VIN, etc.)
