It uses Hall Effect sensors to determine engine speed and position, allowing it to operate in either fixed or variable timing mode. In variable mode, spark advance is adjusted based on manifold pressure and RPM, with base timing set from the engine's data plate at installation. Because it relies on solid-state industrial-grade electronics rather than points, condensers, rotors or caps, the unit is designed to require no scheduled maintenance or overhauls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSpark plug gap : Aviation spark plugs gapped .016 to .036\u003c\/li\u003e\n\u003cli\u003eHarness type : Slick style harness\u003c\/li\u003e\n\u003cli\u003eHarness shielding : Shielded aviation harness\u003c\/li\u003e\n\u003cli\u003eInput voltage : 6-30 volts\u003c\/li\u003e\n\u003cli\u003eAvg. current @2700 : 500mA\u003c\/li\u003e\n\u003cli\u003eStart behavior : Retards spark to TDC for starts\u003c\/li\u003e\n\u003cli\u003eIgnition advance : Up to 38 degrees, RPM \u0026amp; MP based\u003c\/li\u003e\n\u003cli\u003eSensor type : Hall Effect sensors provide velocity and position input\u003c\/li\u003e\n\u003cli\u003eManifold pressure sensor range : 6-74 inHg\u003c\/li\u003e\n\u003cli\u003eOperational temp range : -35 to 250 F\u003c\/li\u003e\n\u003cli\u003eMinimum MTBF : 2000 hrs\u003c\/li\u003e\n\u003cli\u003eInspection interval : No interval inspections\u003c\/li\u003e\n\u003cli\u003eRPM range : 0-3500\u003c\/li\u003e\n\u003cli\u003eSpark energy : Minimum 35mJ spark energy, 50mJ nominal energy\u003c\/li\u003e\n\u003cli\u003eRuntime reference : Run it to 2,400 hours of SIM operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePlease Note\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIf your aircraft battery is located in the tail, a longer power wire must be purchased separately.\u003c\/li\u003e\n\u003cli\u003eIncluded power wire harness is 84\" long, 14ga. wire with inline fuse holder, 10A fuse and ring terminals.\u003c\/li\u003e\n\u003cli\u003eIncluded manifold pressure hose is 36\" long, 1\/8\"ID x 1\/4\"OD high temp. rubber hose.\u003c\/li\u003e\n\u003cli\u003eEngine STC paperwork and Airframe STC paperwork are included in the box.\u003c\/li\u003e\n\u003cli\u003eVariable timing mode requires: normally aspirated engine\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Aircraft Spruce","offers":[{"title":"Default Title","offer_id":51718571589938,"sku":"08-17074","price":3227.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0886\/9494\/8146\/files\/08-17074.png?v=1788554322","url":"https:\/\/www.fractionairparts.com\/products\/surefly-sim4p-4-cylinder-impulse-coupled-magneto-replacement","provider":"FractionAIR Parts","version":"1.0","type":"link"}
