Introducing the new Syvecs Toyota CorollaGR AWD module which is a standalone AWD/4WD/Centre Diff controller designed to take full control of the AWD system in a CorollaGR.

OEM designed controllers are locked down and not adjustable, but by simply fitting the CorollaGR AWD Module a whole new level of control is available and no more AWD instant drop outs on the circuit!

The Corolla GR 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.

The Diff Mode Buttons on the Corolla is used for Map switching which allows users to be able to change between AWD Select 1, 2 and 3 duty maps live to adjust the AWD clamping.  You can also enable the burnout mode to be active when Hazards, Handbrake, or external switch is active.

Syvecs also sells an optional loom to allow external Burnout switches to be mounted and 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. (Rally Cars only and must be ordered with the Unit) Please contact USR if you have questions.

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 or mid corner!

With the use of 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.

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