The Simos18 is a series of ECUs (Engine Control Units) utilized in a broad range of Volkswagen AG vehicles. The ECUs are manufactured by Continental-Siemens and are based on the Infineon Tricore CPU.
An Engine Control Unit accepts stimulus from various sensors attached to an engine, and is responsible for then running the control systems driving the engine itself. Such inputs include one or several cam angle sensors, crankshaft trigger sensors, air pressure sensors, and position actuators for the accelerator pedal, throttle plate, and turbocharger actuators. This document is not intended to explain engine control principles from a base level and assumes the reader is familiar enough with engine control systems to recognize the value in replacing the calibration data used in tuning the ECU's control systems.
The Simos18 contains either the Infineon SAK-TC1791S-384 F200EP processor ("Simos18.1") or the SAK-TC1791S-512 F240EP processor ("Simos18.10").
