Porsche 997.1/.2 4WD Controller




Introducing the new Porsche 997.1 / 997.2 Syvecs AWD module which is a standalone AWD/4WD controller designed to control any AWD/4WD Solenoid/Motor to a maximum of 30 Amps via pin sharing logic.

OEM designed controllers are locked down and not adjustable, but by simply fitting our AWD Module a whole new level of control is available. The unit allows users to optimise control and provide the best performance available from the powertrain.

The 997.1 / 997.2 version of the controller replicates all the OEM CAN information as well as pick up lots of variable from the OEM Can to link into the control strategies like Steering Angle, Brake Pressure, Rpm, Tps, Lateral G, Long G, Speeds, Temperatures and mode switches

Limp Protection options for large slip, high current, high temps which warn the driver but keep awd active unlike the OEM controllers which shut down the outputs which is not ideal with high horsepower!

Works with any Engine management System

The Sport Mode Button on the 997’s is used for Map switching so allows users to be able to change between Awd Select 1, 2, which means all the maps below can be adjusted. You can also enable the burnout mode to be active when the handbrake is present.













With the use of our Scal Software, users can connect to the Device and adjust over 40 maps to adjust the control of the solenoids/motors used in the AWD systems.

Firmware and Software gets updated regularly, check out http://www.syvecs.com/forum/ to make sure you have the latest!
