S7Plus Standalone ECU Kit for M156/M159

The Syvecs S7Plus Mercedes M156/M159 Plug & Play ECU Kit is the first and only complete standalone engine management solution for the Mercedes 6.3L V8 platform. It offers total control over the C63 AMG (W204) and SLS AMG, replacing the factory Bosch ME9.7 ECUs to unlock the full potential of these engines, whether naturally aspirated or modified with forced induction. Engineered with a high-speed RISC processor and a dedicated FPGA, the S7Plus ensures ignition and injection timing are managed with microsecond accuracy. This precision provides the stability required for high-RPM power delivery and demanding track conditions. The system offers advanced features including full CAN Bus integration for seamless communication with the vehicle's network, retaining OEM controls such as 8 switchable engine maps, traction control levels, and launch settings via the factory stalk or steering wheel buttons. It also maintains full factory gauge functionality, warnings, and diagnostic communications. For performance and forced induction applications, the S7Plus includes dedicated logic for managing supercharger bypass valves on popular conversions (e.g., Weistec), fully adjustable closed-loop boost control with safety trims for turbo speed, air charge, and EGT (requires upgraded MAP sensor), and automatic, real-time flex fuel adjustments for Ethanol content. It also supports rolling anti-lag for instant boost buildup while cruising. Engine protection is a key focus, with configurable safety trips monitoring critical parameters like oil temperature, fuel pressure, and individual cylinder knock. The ECU can trigger a "Limp Home" mode or fuel cut to prevent engine failure if a lean condition or pressure drop is detected. Technical specifications include compatibility with M156 (C63, E63, CLS63, etc.) and M159 (SLS AMG) engines, 22 Inputs and 30 Outputs (High/Low Side Drivers), up to 8 hours of internal data logging at 1000Hz, and 100MHz Full Duplex Ethernet connectivity.
