While the specific features of a patched firmware can vary widely depending on the device and the nature of the patch, here are some general possibilities:

The firmware is stored as a . This is the compiled code that tells the microcontroller (usually a Microchip PIC18F458) how to communicate with the car’s CAN-bus and K-Line systems. Why Use a "Patched" HEX File?
