How-To

1. Obtain ECU
2. Take external pics
   • Mostly for all the numbers and letters/the stickers
3. Open ECU
4. Remove PCB
5. TAKE MORE PICTURES (before you touch anything else)
   • The code on the plug socket
   • The microprocessor
   • The EPROM (if there is one)
   • Any and all visible marking on components
   • The entire board on both sides
6. RECORD all components with visible markings, decode resistor values
   • This means a table with the PCB Silkscreen references and the components values
