The Syvecs SYV-4WDCorolla is a professional-grade standalone AWD/4WD controller module for the Toyota GR Corolla. It is designed to provide complete control of the GR-Four all-wheel drive system, especially in track, rally sprint and high-performance street applications where standard AWD logic limits performance.

The system controls the car's center differential and all-wheel drive system with fully adjustable maps and strategies, while maintaining OEM CAN integration and the functionality of the car's other systems.

Key features

Full AWD torque control

• Adjustable front/rear wheel drive distribution for different situations

• AWD engagement control during launch and gear changes

• Map-specific AWD strategy for different surfaces and grip conditions

• Possibility to deactivate or limit AWD (2WD / burnout mode)

• Precise AWD clutch pressure adjustment

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

Driving control & performance

• Better grip in track, rally sprint and winter conditions

• AWD strategies with traction control and launch control functions

• Live map switching with diff mode buttons (AWD Select maps)

• Optimized torque distribution for different speeds, loads and G-forces

The controller utilizes data from the car's CAN bus such as steering angle, brake pressure, RPM, wheel speeds, G-forces and temperatures for precise AWD strategy.

Safety & Security

• Limp protection for slip, temperature and current

• AWD remains active safely even in critical situations

• Protection against solenoid and motor failures

• AWD cooling pump control

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

Data & adjustment

• Over 40 adjustable maps for AWD strategies

• Full adjustment with Syvecs SCal software

• CAN data transmission to other ECUs and instrument clusters

• Support for external sensors and adjustment potentiometers

• Full control over the GR-Four AWD system

• Better starts and better traction control

• Optimized AWD strategy for track and rally use

• Full integration with Syvecs ECU systems
