Fitting the Corolla GR AWD module provides a new level of control and prevents instant AWD dropouts on the circuit. It replicates all OEM CAN information and uses variables from the OEM CAN system within its control strategies, including steering angle, brake pressure, RPM, TPS, lateral G, yaw, longitudinal G, speeds, temperatures, and mode switches.\u003c\/p\u003e \u003cp\u003eThe Corolla GR differential mode buttons provide live switching between AWD Select 1, 2, and 3 duty maps to adjust AWD clamping. Burnout mode can also be activated using the hazard lights, Handbrake, or an external switch.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eAn optional loom supports external burnout switches and live adjustment potentiometers, allowing AWD duty adjustment while driving or 2WD activation at the flick of a switch. This is for rally cars only and must be ordered with the unit.\u003c\/li\u003e \u003cli\u003eLimp protection is provided for excessive slip, high current, and high temperatures, warning the driver while keeping AWD active rather than shutting down the outputs.\u003c\/li\u003e \u003cli\u003eSyvecs SCal software provides access to more than 40 maps for controlling the solenoids and motors used in the AWD system.\u003c\/li\u003e \u003cli\u003eExternal sensors can be connected to the AWD module and linearized using SCal software.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Firmware and software are updated regularly.

It slowly reduces current to the AWD solenoid instead of fully releasing it like the OEM controller. The rear axle is disengaged only when 2WD mode is active or the Handbrake is pulled.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eQuestion:\u003c\/strong\u003e Can the module provide more than 70% rear bias, and does its 30\/70% rear bias feel different from the stock system?\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAnswer:\u003c\/strong\u003e The module can run more RWD bias than the OEM unit. Testing by a dealer on an advanced MAHA dyno achieved slightly more Torque at the rear than the OEM unit by increasing current through the solenoid. This is fully adjustable in the software, and the base map sets Track mode to use this higher current and duty.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eQuestion:\u003c\/strong\u003e What are the benefits if rear bias and clutch-pack temperature limits remain similar to stock?\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAnswer:\u003c\/strong\u003e The fully adjustable unit allows live RWD bias adjustment through the software, OEM buttons, or external potentiometers. The control strategy can be configured for tyre sizes, engine Torque curve, temperature-limit requirements, and other vehicle specifications. Toyota uses the unit for rally builds for these reasons.\u003c\/p\u003e \u003ch3\u003eSpecifications:\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eMaximum Current: 30 amps via pin sharing, HBR1 and HBR2 or HBR3 and HBR4\u003c\/li\u003e \u003cli\u003eCurrent Monitoring: Onboard monitoring of each output\u003c\/li\u003e \u003cli\u003eCAN Bus: 2 x configurable transmit channels via SCal software\u003c\/li\u003e \u003cli\u003eAnalog Inputs: 4 x inputs for assigning a burnout switch, adjustment potentiometer, pressure sensor, and temperature sensor\u003c\/li\u003e \u003cli\u003eABS Sensor Inputs: 4 x magnetoresistive inputs for direct speed monitoring\u003c\/li\u003e \u003cli\u003eUSB Connection: Dedicated SCal software with full calibration control\u003c\/li\u003e \u003cli\u003eMain Power Control: Circuit controlled by the ignition switch\u003c\/li\u003e \u003cli\u003eProtection: Reverse-polarity protection\u003c\/li\u003e \u003cli\u003eEnclosure: Weatherproof\u003c\/li\u003e \u003cli\u003eTemperature Capability: 125°C\u003c\/li\u003e \u003cli\u003eOperating Voltage: 6–25 V\u003c\/li\u003e \u003c\/ul\u003e","brand":"SYVECS","offers":[{"title":"Default Title","offer_id":43130110214324,"sku":"SYV-4WDCorolla","price":1254.74,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/2605\/3812\/files\/syvecs-syv-4wdcorolla.jpg?v=1789644840","url":"https:\/\/atomic-shop.eu\/products\/syvecs-syv-4wdcorolla-awd-controller-for-toyota-gr-corolla-gzea14","provider":"ATOMIC-SHOP Performance Parts \u0026 Motorsport Equipment - EU","version":"1.0","type":"link"}
