  • Coding (FA/VO and FDL editing): Changing parameters within existing ECU software (e.g., turning off legal disclaimers). This is low-risk.
  • Programming (Flashing): Updating the actual firmware version of an ECU. This carries a high risk – a failed flash due to power loss or cable disconnect can brick an ECU.
