An IC programmer for cars is used to read, write, and modify data stored in integrated circuits (ICs) found in automotive electronic modules. It plays a crucial role in ECU (Engine Control Unit) tuning, immobilizer data extraction, and EEPROM/Flash memory editing. Technicians use it to repair or clone ECUs, especially when replacing damaged control units. IC programmers can access chip-level data, enabling advanced diagnostics and customization. They support a variety of automotive IC types, including EEPROMs, microcontrollers, and flash chips. These tools are widely used in automotive electronics repair, key programming, and mileage correction.
