The Syvecs SYV-4WD991 is a professional-grade standalone AWD/4WD controller module for the Porsche 991.1 and 991.2 Carrera 4 and Turbo models. It is designed to provide complete control of the 991 chassis' all-wheel drive system, especially for track, drag and high-performance project builds where standard AWD logic limits performance.

The system enables fully adjustable torque distribution and AWD strategy with OEM CAN integration and works with any engine management system.

Key features

Full AWD torque control

• Adjustable front/rear wheel drive distribution for different situations

• AWD strategies during launch and gear changes

• Map-specific AWD adjustment for different grip conditions

• Possibility to deactivate AWD or enter burnout mode

• Control of AWD solenoids up to 30A with pin-sharing logic

OEM AWD controllers are locked down with no adjustment options – Syvecs allows for fully customizable AWD operation.

Driving control & performance

• Better grip in track and drag use

• AWD strategies with traction control and launch control functions

• Map change with OEM Sport Mode button (AWD Select modes)

• Optimized torque distribution based on speed, load and G-forces

The controller utilizes vehicle CAN data such as steering angle, brake pressure, RPM, throttle position, G-forces, temperatures, and wheel speeds to generate precise AWD strategies.

Safety & Security

• AWD remains active in critical situations

• Overheating and overcurrent protections

• AWD cooling pump control

Standard controllers can completely disengage AWD under load – Syvecs safely maintains control.

• Support for external sensors and adjustment potentiometers
