Description
The Syvecs VAG MQB4 AWD Controller module is a standalone AWD/4WD/Centre Diff controller. It has been designed to control the haldex system on VAG group MQB cars.
The MQB version of the controller replicates all the OEM CAN information. It also picks up lots of variables 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. This is unlike the OEM controllers which shut down the outputs. This is not ideal with high horsepower!
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.
Syvecs VAG MQB4 AWD Controller Calibration Switch
With the use of the Syvecs 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.
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.
