The system independently detects crankshaft and camshaft position signals, providing more accurate engine speed and crank angle data for advanced engine management and tuning.\u003c\/p\u003e \u003cp\u003eThe factory SR20DET system generates the crankshaft position signal through the cam angle sensor. Timing chain movement can introduce significant signal variation, particularly at high engine speeds. By separating the crankshaft and camshaft signals, the HKS kit enables more stable engine speed recognition under high-load and high-RPM operating conditions.\u003c\/p\u003e \u003cp\u003eThe kit uses a dedicated ATI crank damper pulley with an integrated trigger wheel. The trigger phase is optimized according to the crankshaft sensor position to support reliable engine starting. Dedicated harnesses, brackets, and related installation components simplify fitment, while the harness incorporates noise countermeasures and can replace aged factory wiring.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eSeparately manages crankshaft and camshaft position signals\u003c\/li\u003e \u003cli\u003eImproves crank angle and engine speed signal accuracy\u003c\/li\u003e \u003cli\u003eReduces signal variation caused by timing chain movement\u003c\/li\u003e \u003cli\u003eSupports stable signal recognition at high engine speeds and under high load\u003c\/li\u003e \u003cli\u003eExpands engine management and tuning capabilities\u003c\/li\u003e \u003cli\u003eIncludes a dedicated ATI crank damper pulley with an integrated trigger wheel\u003c\/li\u003e \u003cli\u003eOptimized trigger phase supports reliable engine starting\u003c\/li\u003e \u003cli\u003eDedicated harness includes countermeasures against electrical noise\u003c\/li\u003e \u003cli\u003eReduces peak crankshaft torsional vibration at resonance points\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eSpecifications:\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eCompatible Engine: SR20DET\u003c\/li\u003e \u003cli\u003eTrigger Wheel Configuration: 36-2\u003c\/li\u003e \u003cli\u003eTrigger Wheel Phase: 180 degrees out of phase\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eInstallation Notes:\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eRequires an ECU that supports custom sensor configuration, such as the HKS F-CON V Pro\u003c\/li\u003e \u003cli\u003eInstallation and calibration require advanced technical knowledge\u003c\/li\u003e \u003cli\u003eIncorrect installation or calibration may result in serious engine problems or engine damage\u003c\/li\u003e \u003cli\u003eInstallation and setup through an HKS Power Writer Shop are recommended\u003c\/li\u003e \u003cli\u003eDeteriorated ignition coils may generate electrical noise that interferes with ECU signals and causes incorrect engine speed recognition\u003c\/li\u003e \u003cli\u003eReplacement with HKS SUPER FIRE RACING COIL PRO 43005-AN004 or 43005-AN005 is recommended when the ignition coils are worn\u003c\/li\u003e \u003cli\u003eCompatibility with naturally aspirated SR20DE engines has not been confirmed\u003c\/li\u003e \u003cli\u003eS15 vehicles using an HKS F-CON V Pro require a fuel cell or equivalent fuel system modification because the factory canister system uses solenoid control and may leave insufficient control channels available\u003c\/li\u003e \u003c\/ul\u003e ","brand":"HKS","offers":[{"title":"Default Title","offer_id":44332340609204,"sku":"45999-AN004","price":3874.64,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/2605\/3812\/files\/hks-45999-an004_20-1_1_26544177-5257-4e0a-81d7-016f61a34403.jpg?v=1785828220","url":"https:\/\/atomic-shop.eu\/products\/hks-45999-an004-crank-angle-sensor-conversion-kit-sr20-for-nissan-180sx-rps13-sr20det-engine-silvia-s13-s14-s15-sr20det-engine","provider":"ATOMIC-SHOP Performance Parts \u0026 Motorsport Equipment - EU","version":"1.0","type":"link"}
