Ruzic Engineering GTR 4WD Torque Split ControllerDesigned and Optimised for Circuit Racing 
The Nissan Skyline GTR has the ability to proportion drive torque to the front wheels at a continuously variable rate. The on board 4WD computer determines the torque split based on sensor inputs. The maximum torque to the front wheels can be up to 50%. The 4WD Controller has been designed to alter the lateral G Force signal read by the 4WD computer. This in turn allows the device to alter the way the torque split is applied to the front wheels. It will apply the front wheel drive earlier, or later, depending on the setup. The device has five different ‘maps’ (each with 32 individual set points for fine tuning) that can be used to alter the front torque split. These range from a simple line, to curves that allow the car to run as factory during low G Force curves, but apply more front torque for higher G Force curves. By using an external toggle switch it makes it possible to setup two different handling strategies and transfer between them instantly. This feature allows the driver to optimize handling for different corner types at the race track. It is possible to have one setup for high speed corners and a different setup for off camber switchbacks. With the device connected to the lateral G, longitudinal G and 4WD percentage signals, the user can perform handling analysis and determine how each map and scale factor setting is affecting the traction circle and grip of each turn at the track. Data logging can be performed by using a memory option. The device will log to a laptop, or external memory. The data logging can log values at rates up to 20 samples per second. Features
