The Syvecs R35 GT-R AWD Module is a standalone AWD / 4WD / centre diff controller designed to control any AWD/4WD solenoid or motor up to a maximum of 30 amps via pin sharing logic. OEM controllers are locked down and not adjustable; fitting the Syvecs AWD Module opens up a whole new level of control so you can optimise the powertrain's performance.
The R35 GT-R version replicates all the OEM CAN information and also picks up variables from the OEM CAN bus to feed the control strategies, including steering angle, brake pressure, RPM, TPS, lateral G, yaw, longitudinal G, speeds, temperatures and mode switches.
The R Mode button on the R35 GT-R is used for map switching, allowing users to change between AWD Select 1 and 2. Burnout mode can be set to activate with Snow mode, with the hazards on, or when the handbrake is applied. Syvecs also sells an optional loom for external burnout switches and live adjustment potentiometers, giving the driver the ability to adjust AWD duty on the move or switch to 2WD.
Limp protection options cover large slip, high current and high temperatures. They warn the driver but keep AWD active, unlike the OEM controllers which shut the outputs down entirely, which is far from ideal with high horsepower.
Calibration (over 40 maps via Scal software)
- 4 x base duty tables
- 4 x adders with enable maps: left foot braking, front slip, rear slip, centre slip
- 4 x multipliers with enable maps: steering angle, AWD temp, AWD pressure, AWD potentiometer
- Tyre diameter adjustment under sensors
- 2WD / burnout mode via dedicated switched input, CAN bus message or OEM functions
- Limiters: maximum duty, launch control limit, duty rate of change, decay/hold functions
- Limp mode: over current, over slip and over temp protection
- AWD cooling pump control logic
- Dedicated CAN bus transmit area for sending variables to external control units or OEM CAN systems via custom identifiers and byte structuring
- External sensors can be connected and linearized in Scal
