GT-R35 Syvecs AWD Controller

Description

GT-R35 Syvecs AWD Controller

Introducing the new Syvecs R35GTR AWD module which is a standalone AWD/4WD/Centre Diff 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 optimize control and provide the best performance available from the powertrain.

The R35GTR 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 R Mode Button on the R35GTR 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 Snow mode is active, Hazards are on, or if the handbrake is present.

Syvecs also sells an optional loom to allow external Burnout switches to be mounted and Live adjustment potentiometers which give drivers the ability to adjust the AWD Duty on the move or go 2wd from the flick of a switch.

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!

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.

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

AutoShift

The Syvecs AWD unit has a spare output that can be used for sending an output signal (lowside) to a Shift light or an Up-Paddle lever.
This is particularly useful with high power applications as drivers won’t pull the paddle quick enough in the lower gears and miss the optimal
shift point or hit the rev-limiter.

On Firmware level 1.15 + , a change light strategy is present which can be used to replicate an Upshift paddle on the car. This can be done
based on speed, tps and rpm.

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
