Description SYVECS S7Plus-BE46 Engine ECU S7Plus Kit for BMW M3 (E46)

The Syvecs BMW E46 M3 Standalone ECU Kit brings an entirely new level of engine management control to the BMW M3 platform, featuring the world's first fully standalone ECU solution for the S54 engine.

Compatible with manual transmission vehicles only. The plug-in kit provides a comprehensive range of advanced motorsport and performance features.

Key Features:

• Full live tuning; complete OEM VANOS control; Flex Fuel capability; optional cruise control; flat-shift functionality; four pedal-to-throttle maps; selectable engine maps, boost levels, traction control settings, and launch control strategies through a 12-position rotary switch.
• Adjustable launch control with anti-lag strategies and Torque ramp-in maps; rolling anti-lag and pit lane limiter strategies; four target slip maps; traction control using wheel speeds, steering angle, and lateral G-force inputs; ignition-retard or fuel-cut Torque reduction; adjustable post-launch Torque ramp control; customizable throttle blip strategies.
• Dual closed-loop lambda control using LSU4.9 wideband sensors, sold separately; control of OEM and supplementary injectors; support for high- and low-impedance injectors; adjustable injector dead-time compensation and end-angle control; closed-loop boost control; exhaust gas temperature monitoring and trimming; fuel pump control and fuel pressure monitoring; individual-cylinder closed-loop knock control and optional cylinder shutdown.
• Up to eight hours of onboard data logging at rates up to 1000 Hz; RJ45 Ethernet communications; anti-theft and valet modes; configurable engine protection; support for MAP sensors up to 7 Bar; integration of external sensors, including crankcase pressure and Suspension Shock absorber / Damper position; support for alternative drive-by-wire Throttle bodies; wet and dry nitrous oxide control; CAN Bus integration; built-in oscilloscope functionality; and control of active aerodynamics, Exhaust Valves, Cooling systems, and other external vehicle functions.

Frequently Asked Questions:

OBD port and vehicle diagnostics: Standard BMW diagnostic tools can still read and clear fault codes from systems such as ABS, DSC, and body modules. The engine ECU will no longer be accessible through BMW diagnostic software. Engine diagnostics and fault management are performed through Syvecs SCal software.

Traction control operation: The Syvecs traction control system offers improved performance over the factory strategy. The OEM ESP button can be assigned within SCal using AN20, allowing traction control settings to be adjusted or disabled.

Fuel consumption gauge with larger injectors: The fuel consumption calculation can be adjusted under SCal, Fuel Consumption, Injector Consumption Scaling. A suitable starting point is injector size divided by 60.

Switching between calibrations and maps: The recommended solution is a Syvecs Calibration Rotary Switch, available through Syvecs or an authorized dealer. It provides instant access to multiple maps, traction settings, boost levels, and launch control configurations.

Fueling and ignition for turbocharged applications: The supplied base calibration uses the naturally aspirated Alpha-N strategy. For forced-induction applications, a MAP sensor can be connected to a spare ECU input. Additional fueling can be configured under Run Mode, Fueling, Corrections, Simple Manifold Pressure Multiplier. Ignition timing can be adjusted under Run Mode, Ignition, Corrections, Simple Manifold Pressure Adder.

Wideband lambda sensor support: The kit supports dual LSU4.9 wideband lambda sensors as standard and can also be built with an option for dual NTK sensors.

Additional parts: Turbocharged or supercharged applications require an external MAP sensor wired into the plug-in adapter.
