Syvecs Fast Response Air Temp Sensor The Syvecs Fast Response Air Temp Sensor is a high-performance open-element thermistor designed for precision intake air temperature (IAT) monitoring. Based on the widely used GM open-element architecture, it is engineered to provide the rapid thermal tracking required for high-boost forced induction systems. Its open design allows airflow to pass directly over the sensing element, providing response times significantly faster than standard brass-encased fluid temperature sensors. This sensor is a vital component for accurate air charge calculation, allowing your Syvecs ECU to apply real-time ignition timing and fueling corrections to protect the engine during high-load conditions. Performance and Precision Engineering The sensor is built for professional motorsport environments where standard sensors may suffer from heat soak or lag. Open-Element Design: Provides a rapid response time, ensuring the ECU sees temperature shifts during a pull or under anti-lag conditions. Thermal Stability: Features a wide operating range from -40C to +135C. Rugged Construction: Built with a heavy-duty brass body and high-temperature internal sealing. Full Compatibility: Works with all Syvecs Engine Management Systems as well as other standalone ECUs. Calibration and Wiring Data This sensor is an NTC (Negative Temperature Coefficient) thermistor. While Syvecs software (SCal) contains this sensor in its built-in database, the following resistance data can be used for manual entry. Note: Syvecs ECUs typically use a 3k Ohm internal pull-up resistor. Resistance Table: -40C = 100,700 Ohms 0C = 9,420 Ohms 20C = 3,400 Ohms 40C = 1,450 Ohms 80C = 332 Ohms 100C = 177 Ohms Electrical Pinout: This is a non-polarized 2-wire sensor. Pin A: Signal (Connects to ECU Analog Input) Pin B: Sensor Ground (Connects to ECU Sensor Ground) Technical Specifications Feature Details Part Number SYV-ACT Process Connection 3/8 NPTF Thread Response Time Less than 10 Seconds Accuracy +/- 1C Operating Range -40C to +135C Supply Voltage 5V via 3k pull-up Construction Brass body with Open-Element cage Weight 20g
