Syvecs AWD/4WD Controller - VAG MQB Haldex GEN5

The Syvecs MQB AWD module is a standalone AWD/4WD/Centre Diff controller designed to control the haldex system VAG group MQB cars. This includes the following and more.

Audi S3
Seat Leon Cupra
VW Golf R7.1
VW Golf R7.5

Please note this unit will not work with the RS3/TTRS, you will require the Special controller from Iroz motorsport for this. Please see the dedicated product page for the RS3/TTRS 4wd module

The OEM haldex controller 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 MQB 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, Yaw, 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 Drive Mode Button on the MQB is used for Map switching so allows users to be able to change between Awd Select 1, 2, 3 which means all the maps below can be adjusted. You can also enable the burnout mode to be active when Hazards are on or if handbrake is present.

Live adjustment potentiometers which gives drivers the ability to adjust the AWD Duty on the move or go 2wd from the flick of a switch.

Datastream

The Syvecs AWD Unit also has a dedicated Can bus transmit area where users can send variables from the AWD to external control units for monitoring or to OEM Canbus system via custom Identifiers and byte structuring

Sensors / Switches

External sensors can be connected to the AWD module and then linearized in our Scal Software

When the AWD is fine tuned to suit torque and chassis setups then huge improvements can be gained with our modules in acceleration as Adam showcases below
