Syvecs 4WD/AWD Controller Porsche 991.1 / .2

Syvecs Standalone AWD Controller | Porsche 911 (991.1 / 991.2)

The Syvecs Porsche 991 Standalone AWD Controller is the ultimate performance upgrade for the 991.1 and 991.2 chassis drivetrain. While the factory Porsche Traction Management (PTM) is highly capable, it is programmed with conservative, safety-biased logic that often limits performance on high-horsepower cars. The Syvecs unit replaces the factory AWD module to provide absolute authority over the center coupling, allowing for custom torque distribution that transforms the 991 from a safety-oriented GT into a precision-balanced weapon.

By taking control of the electronically controlled multi-plate clutch, this controller allows for a level of chassis tuning previously reserved for Weissach engineers. It is the definitive solution for eliminating mid-corner understeer and maximizing the effectiveness of the AWD system in high-torque Twin Turbo applications.

Dynamic Torque Vectoring & Integration

The Syvecs AWD Controller is a fully programmable motorsport computer that communicates fluently with the Porsche high-speed CAN bus:

• OEM Drive Mode Integration: The controller reads the factory Normal, Sport, and Sport Plus settings. You can assign a unique AWD map to each mode—allowing for a playful, rear-biased "Sport" logic and a maximum-traction, rock-solid "Sport Plus" logic.

• Launch Control Mastery: Specifically designed to work with Porsche’s PDK launch strategies. The controller "pre-loads" the AWD system the moment it detects Launch Control activity, ensuring the front wheels are fully engaged before the torque hits the ground, resulting in record-breaking 0-60 and 60-130 times.

• Live Sensor Processing: The unit processes real-time variables including Steering Angle, Lateral-G, Brake Pressure, and Individual Wheel Speeds. It dynamically adjusts the AWD clutch clamping pressure in milliseconds to provide grip exactly when it’s needed.

• Burnout Mode: Enables the ability to instantly decouple the front axle for 2WD operation. This is essential for tyre warming at the drag strip or for dyno testing on 2WD rollers.

Performance & Safety Features

• AWD Protection Logic: The Syvecs controller monitors internal AWD clutch temperatures and pressure. If the system detects overheating during extreme track use, it triggers a safety strategy to protect the mechanical components—preventing the "AWD Overheat" errors common on tuned 991s.

• User-Programmable Maps: Via the Syvecs SCal software, tuners can create custom duty tables based on any CAN variable. You can increase front-drive during high-speed stability runs or reduce it during tight, low-speed cornering to improve turn-in and rotation.

• Plug & Play Installation: Designed to plug directly into the factory wiring loom. The installation is fully reversible and requires no permanent modifications to the vehicle's electrical system.

Technical Specifications

The Standard for Porsche Performance

For 991 Turbo owners pushing 1000hp+, the factory AWD logic is the "weak link" in achieving consistent sub-2.5s 0-60mph times. The Syvecs AWD Controller ensures that the front tires are utilized effectively to pull the car forward rather than just reacting to rear-wheel spin. It is the professional choice for tuners who demand a car that is as stable at 200mph as it is aggressive off the line.
