SYVECS SYV-4WD997 AWD Controller for PORSCHE 911 Carrera 4 / 911 Turbo (997.1 / 997.2) 2004–2012

Description SYVECS SYV-4WD997 AWD Controller for PORSCHE 911 Carrera 4 / 911 Turbo (997.1 / 997.2) 2004–2012

The Porsche 997.1/997.2 Syvecs AWD module is a standalone AWD/4WD/centre differential controller designed to control any AWD/4WD solenoid or motor up to a maximum of 30 amps via pin-sharing logic.

Unlike locked OEM controllers, the AWD module provides adjustable powertrain control. It replicates OEM CAN information and uses variables such as steering angle, brake pressure, RPM, TPS, lateral G, longitudinal G, speeds, temperatures, and mode switches within its control strategies.

Using Syvecs Scal software, operators can connect to the device and adjust more than 40 maps controlling the solenoids or motors used in AWD systems.

Note: Firmware and software are updated regularly. Check http://www.syvecs.com/forum/ for the latest versions.

• Limp protection for excessive slip, current, and temperature warns the driver while keeping AWD active.
• Compatible with any engine management system.
• The Porsche 997 Sport Mode button provides switching between AWD Select 1 and 2.
• Burnout mode can be enabled when the handbrake is engaged.

Available Maps:

• 4 x base duty tables
