HV High Temp Fast Response Charge-Air & Fluid Sensor — Calibration Table, Pinout & Archive Spec
The HV High Temp Fast Response Sensor (HV-IAT-FR200, archived at $144.00 NZD) uses an exposed micro-bead NTC element in an M10×1.0 housing to achieve sub-1.4-second thermal response up to +200°C. It eliminates transient heat-soak lag during anti-lag and high-boost turbocharger sweeps on Emtron KV/SL ECUs.
