Do not disable the knock control completely. The simos18.1 uses Ionization current sensing (measuring combustion via the spark plug). If you turn this off, the ECU goes into limp mode immediately.
The is a high-performance Engine Control Unit (ECU) found in many modern Volkswagen Group (VAG) vehicles, particularly those powered by the 1.8L and 2.0L TSI/TFSI petrol engines. As part of the MQB platform, this ECU is central to the performance and drivability of popular models like the VW Golf GTI, Audi S3, and various Skoda and SEAT variants. 1. Technical Architecture At its core, the Simos 18.1 simos18.1
Simos 18.1 is a cost-optimized yet capable ECU for mid-range MQB turbocharged engines. It is for high-horsepower builds (above 450hp) due to injection timing limits and weaker torque model, but it is well understood and tunable via OBD tools with RAM-patch unlock. Do not disable the knock control completely
The simos18.1 is a 32-bit engine management system based on an Infineon Tricore architecture (specifically the TC-1796 or TC-1797 family). It succeeded the earlier simos16 and simos12 units, bringing significant improvements in processing speed and real-time computing. The is a high-performance Engine Control Unit (ECU)
Researchers have identified "leaks" in early CBOOT versions that allow for the promotion of forged security headers, making it possible to install custom firmware on these ECUs. Common Troubleshooting VW_Flash/README.md at master - GitHub
