{"product_id":"three-step-module-selector","title":"MSD 8737 - Three Step Module Selector","description":"\u003cp\u003eAs an example, we'll use a drag car with a Three Step Module Selec­tor plugged into the rpm socket of a 7AL-2 Ignition. The different rpm modules are activated when 12 volts are applied to a corresponding wire. By connecting one wire to the line-lock circuit, one module will be activated during the burnout. This helps keep tire temperatures consistent. When the line-lock button is released, the limit turns off. When you're on the starting line, you can activate the second limit through the clutch or trans switch. This provides a steady and consis­tent rpm for firm holeshots every time. When no modules are selected, the remaining high limit is active to protect the engine in the event of driveline failure.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eLaunch rev limiter\u003c\/li\u003e\n\u003cli\u003eBurnout rev limiter\u003c\/li\u003e\n\u003cli\u003eSet 3 RPM limits:\u003c\/li\u003e\n\u003cli\u003eTop End rev Limiter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e MSD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Air and Fuel Delivery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmission Code:\u003c\/strong\u003e 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epart type:\u003c\/strong\u003e Engine RPM Limiter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Module Selector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSub Category:\u003c\/strong\u003e Fuel Injection System and Related Components\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Manufacturer's Limited 1 Year Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWarranty:\u003c\/strong\u003e Manufacturer's Limited 1 Year Warranty\u003c\/p\u003e","brand":"MSD","offers":[{"title":"Default Title","offer_id":45520786980999,"sku":"MSD8737","price":308.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4008\/1543\/files\/8737_01.jpg?v=1788269315","url":"https:\/\/checkout.northernperformance.ca\/products\/three-step-module-selector","provider":"Northern Performance","version":"1.0","type":"link"}
