Syvecs Calibration Switch The Syvecs Calibration Switch is a high-quality rotary selector that allows drivers to change engine maps and vehicle strategies on the fly without the need for a laptop. Connected to a single analog input on the Syvecs ECU, this switch provides an intuitive way to toggle between different levels of performance, fuel types, or safety settings. Whether you need to switch from a low-boost street map to a high-boost track map, adjust traction control sensitivity, or toggle between Pump Gas and E85 blends, the Syvecs Calibration Switch provides tactile, reliable control from the driver's seat. Performance and Precision Engineering Designed for motorsport use, the switch features a positive detent "click" for each position, ensuring the driver can change modes confidently even while wearing racing gloves. Multi-Position Versatility: Available in multiple configurations (typically 10 or 12 positions) to suit complex calibration requirements. Voltage Ladder Logic: Uses a high-precision internal resistor array to output specific voltage steps for each position, allowing the ECU to identify the selected map with 100 percent accuracy. Compact Mounting: Designed for easy dashboard or center console installation with a standard rotary dial and labeled bezel. Universal Compatibility: Works with all Syvecs Engine Management Systems, including S7, S8, S12, and Direct-Fit kits. Calibration and Wiring Data The switch operates on a 0V to 5V scale. In the Syvecs SCal software, the user assigns the corresponding analog input to "Cal Switch" and defines the voltage thresholds for each position. Standard Voltage Steps (Typical 12-Position): Position 1: 0.42V Position 2: 0.83V Position 3: 1.25V Position 4: 1.67V Position 5: 2.08V Position 6: 2.50V Position 7: 2.92V Position 8: 3.33V Position 9: 3.75V Position 10: 4.17V Electrical Pinout: Red Wire: 5V Supply (from ECU 5V Ref) Blue/White Wire: Signal Output (to ECU Analog Input) Black Wire: Ground (to ECU Sensor Ground)
