This kit gives you the ability to control timing electronically through a Holley EFI ECU (or other standalone engine management system \/ ignition controller). At the heart of the kit is the 3-wire Hall-Effect Sensor that is easier to set up, less susceptible to EMI\/RFI interference\/noise, and less likely to have false signals than other methods (Distributors and VR Magnetic Sensors). In addition, they are less prone to mechanical failure since there are no wear parts. With the included high quality timing pointer and the use of a direct bolt-on, degreed balancer (see below list for recommendations), you'll be able to adjust timing in the precise increments required for your engine. • Coyote 556-173 We recommend using ATI 918047-MSD but will also work with 918047N and 918047NA • LS 8 inch 556-174 Designed to work directly with ATI 917302, 918852, 917264 or 917242 • LS 7.28 inch 556-175 Designed to work directly with ATI 917777, 917211 or 917234 • LS 6.56 inch 556-176 Designed to work directly with ATI 917776 or 917215\u003c\/div\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMost accurate way to your electronic fuel injection (EFI), can be installed as 12-1 or 12x\u003c\/li\u003e\n\u003cli\u003ePowerful magnets embedded in a 3\/8-inch thick billet 6061-T6 aluminum wheel\u003c\/li\u003e\n\u003cli\u003e3-wire Hall-Effect Sensor that is not easily susceptible to EMI\/RFI Interference\u003c\/li\u003e\n\u003cli\u003eEngine specific kits include a direct bolt-on billet aluminum pick up bracket\u003c\/li\u003e\n\u003cli\u003eRigid mounting that will not flex and cause timing fluctuation\u003c\/li\u003e\n\u003cli\u003eEasy to install much like traditional MSD Crank Kits\u003c\/li\u003e\n\u003cli\u003eIncluded installation instructions cover mechanical setup and provide step-by-step Holley EFI Software Setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cstyle\u003e\u003c\/style\u003e","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":43995519025365,"sku":"556-180","price":276.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2493\/0960\/files\/556-180-a3c01b95274247f4b177a7f4959df600be4889e8.jpg?v=1738372552","url":"https:\/\/moderndaymuffler.com\/products\/universal-8-inch-12-1x-crank-trigger-wheel-556-180","provider":"Modern Day Muffler","version":"1.0","type":"link"}
