Syvecs S7D Plug And Play ECU Kit Audi S3 8V

The Syvecs MQB Plug in ECU is a fully integrated engine management solution designed for Volkswagen-Audi Group (VAG) MQB-platform vehicles equipped with CJXB, CJXC, and closely related engine variants.

Rather than being limited to a single model, this kit supports all MQB-based vehicles using the same engine architecture, delivering a true plug-and-play installation that connects directly to the factory wiring loom with no cutting, splicing, or permanent modification required.

Once installed, the Syvecs ECU unlocks an entirely new level of control and functionality while retaining all standard OEM vehicle operations, making it suitable for both advanced road cars and high-performance motorsport builds.

Supported Platforms (Engine Dependent)

Vehicles based on the MQB platform using CJXB / CJXC or closely related engine codes, including (but not limited to):

• Volkswagen Golf R (Mk7 / 7.1)

• Audi S3 (8V)

• Audi TT S / TTS (8S)

• SEAT Leon Cupra (MQB)

• Škoda Octavia RS (MQB)

(Exact compatibility depends on engine code and vehicle configuration)

Key Advantages

• True Plug-and-Play Integration
  Direct connection to the OEM wiring loom with factory connectors.

• Full OEM System Retention
  Dash, CAN communications, safety systems, diagnostics, and drivability are preserved.

• MQB-Wide Compatibility
  One solution covering multiple VAG models sharing the same engine architecture.

• Motorsport-Grade Engine Control
  Designed for applications where factory ECUs or reflashes become restrictive.

• Scalable for Future Upgrades
  Ideal for big-turbo, ethanol, and high-power configurations.

Advanced Control & Feature Capability

Depending on calibration and vehicle configuration, the Syvecs MQB Kit enables:

• Fully configurable boost control

• Flex-fuel / ethanol strategies

• Advanced torque and traction management

• Custom CAN integration with vehicle systems

• Support for high-flow injectors and upgraded fuel systems

• Motorsport-level engine protection strategies

• Launch control, flat-shift, and advanced driver aids

• High-speed data logging and analysis

All tuning is performed using Syvecs SCal software, providing professional calibrators with complete visibility and control over engine strategy, safety systems, and performance logic.

Designed for Performance Without Compromise

Unlike ECU reflashes that work around factory limitations, the Syvecs MQB Plug-and-Play ECU Kit replaces those limits entirely, while still behaving like a factory vehicle when required.

This makes it ideal for:

• High-power street cars

• Track and time-attack builds

• Motorsport applications

• Customers who want total control without losing OEM integration

Features available with the kit:

• Live tuning of every aspect of the engines calibration, including signals sent to the DSG
• Full Direct Injection and pump control
• 8 Injector support with 4 port injectors
• Torque Control
• Ability to select desired engine map, boost level, traction and launch control levels through steering wheel buttons
• Fully adjustable launch control with anti-lag strategies and ramp in maps
• Full variable valve timing control
• Flex Fuel control
• Cruise control
• Fully functional with every other ECU on the Car
• Closed loop dual Lambda control
• Fully adjustable closed loop boost control with launch level adjustments and trims for turbo speed, air charge, engine coolant temp, exhaust gas temperatures etc..
• Monitor and trimming of exhaust gas temperatures
• Flat Shift
• Built in data logging using a market leading analysis software of up to 8 hours, with data rates at up to 1000hz
• Rolling antilag / pit lane limiter strategies, great for building boost on a roll
• Antitheft and valet modes
• Super fast connection via RJ45 ethernet port for live tuning anywhere in the world or even remotely if on track if connected to a wireless unit.
• Adjustable traction control strategies based on lateral G and individual wheel speed monitoring.
• 4 programmable target slip maps. An immediate torque reduction can be applied by the ECU via ignition retard or a fuel cut.
• Configurable engine safety trips on all important parameters like oil temperature, oil pressure.
• Fuel pump control of both main, and sub pumps, as well as relative fuel pressure monitoring and limiting in the event of fuel pressure dropping on boost.
• 4 different pedal to throttle angle maps with multipliers for different parameters e.g. speed. Again adjustable via steering wheel buttons
• Configurable individual cylinder closed loop knock control, to suit any cylinder modification with adjustments to frequency, windows for listening and gains for each cylinder.
• Ability to trigger full cylinder shutdown in severe knock conditions.
• Change torque reduction levels on shifts. Essential for very high power applications where the maximum reduction available via the stock ECU is not enough to prevent damage to components
• Ability to change torque ramp in after launch
• Change throttle blip requests to match your torque band. Especially useful on oversized turbo installations.
• Run up to 7bar map sensors
• Control high or low impendence injectors
• Control up to 4 additional injectors for high power installations where staged injection may be required
• Change injector dead times based on voltage levels for proper control
• Change injector end angle to ensure injection point is properly calibrated
• Ability to fit any type of external sensor to monitor and trigger safety trips from anything from crank case pressure to damper position
• Ability to use any size DBW throttle body e.g. Chevrolet LS7
• Wet and Dry – Wet and dry nitrous control with ability to drive solenoids directly and control n20 heaters via pressure monitoring
• Ability to control any external vehicle features based on sensor inputs e.g. adjustable rear wing linked to G force or exhaust control valves
• Connect any race series dash or even one of our Syvecs edition SDM displays
• View any input live with built in scope up to 1000hz
• And much, much more!
