The Bosch Motorsport LWS7.3.6 steering wheel angle sensor provides absolute steering angle measurement across ±780° (more than two full turns) and real-time angular velocity up to 1,016 °/s via CAN at 500 kbaud. Both channels are output on a single 4-pin connector — no separate power and signal wiring required beyond the CAN bus connection.
The sensor uses the Giant Magneto Resistive (GMR) effect to detect absolute angular position: toothed measuring gears with different tooth ratios and integrated magnets produce field changes at GMR elements as the shaft rotates. A microcontroller inside the sensor processes the GMR signals and calculates absolute position — meaning the sensor knows its angle from power-on without requiring a calibration rotation or homing procedure at startup. This is the correct behaviour for a racing application where the car may start with the steering at any angle.
Two separate CAN IDs are used: 0x2B0 for the steering angle channel and 0x7C0 for the angular speed channel. Verify these IDs do not conflict with other devices on the CAN bus before installation.
The LWS connector kit is stocked separately and includes the mating 4-pin connector with pins and seals for harness construction.

What You Can Do With It
- Feed steering angle directly to the VCU MS 50.4 for stability and traction control input
- Log steering angle and angular rate in WinDarab V7 for driver coaching and setup analysis
- Use as ABS M5 input for yaw-referenced brake bias modulation
- Measure understeer/oversteer response by comparing steering angle to lateral acceleration (MM7.10 or MM5.10)
- Connect directly to the ECU or data logger via CAN without signal conditioning
