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!
