Syvecs S7Plus Plug & Play ECU Kit | Mercedes-AMG M156 & M159 The Syvecs S7Plus Mercedes M156/M159 Plug & Play ECU Kit is the world’s first and only complete standalone engine management solution for the Mercedes 6.3L V8 platform. This kit provides total authority over the C63 AMG (W204) and the SLS AMG, replacing the factory Bosch ME9.7 ECUs to unlock the true potential of these high-displacement naturally aspirated engines—and their forced-induction counterparts. By utilizing a high-speed RISC processor and a dedicated FPGA, the S7Plus ensures that ignition and injection timing are managed with microsecond accuracy, providing the stability needed for high-RPM power and heavy track use. Total Vehicle & Transmission Integration Unlike generic standalone systems, the Syvecs S7Plus is engineered for full CAN Bus integration, ensuring your Mercedes remains a luxury performance car: TCU Communication: Live tuning of torque control allows for adjusted clutch clamping and optimized shift points in the 7G-Tronic transmission. OEM Controls: Select between 8 switchable engine maps, traction control levels, and launch settings using the factory Cruise Control stalk or steering wheel buttons. Full Dash Functionality: Retains all factory gauges, warnings, and diagnostic communications across the vehicle's network. VVT Control: Complete command over the Variable Valve Timing for both intake and exhaust cams to maximize the V8 torque curve. Performance & Forced Induction Readiness Supercharger Bypass Control: Includes dedicated logic for managing bypass valves on popular M156 supercharger conversions (e.g., Weistec). Turbocharging Support: Fully adjustable closed-loop boost control with safety trims for turbo speed, air charge, and EGT. (Requires upgraded MAP sensor). Flex Fuel Control: Automatic, real-time mapping adjustments based on Ethanol content for maximum power on E85. Rolling Anti-Lag: Build boost instantly while cruising—perfect for high-speed roll racing and overtaking.
