That margin is not a mistake. It is simply not tuned for one bike, one climate and one exhaust system.\u003c\/p\u003e\n\u003ch2\u003eBuying With an Exhaust Already Fitted\u003c\/h2\u003e\n\u003cp\u003eThis is the most common situation and the clearest case. A motorcycle running an aftermarket silencer on the standard map is working with a mixture the factory never intended it to have.\u003c\/p\u003e\n\u003ch2\u003eA Component, Not a Project\u003c\/h2\u003e\n\u003cp\u003eSome tuning parts start a conversation that lasts a season. This one is fitted on a Sunday afternoon and then never thought about again, which for most owners is exactly the point.\u003c\/p\u003e\n\u003ch2\u003eNothing Upstream Notices\u003c\/h2\u003e\n\u003cp\u003eThe engine controller issues its instruction and the module modifies it afterwards. From the controller's point of view the motorcycle behaves exactly as it always has, which is why nothing is logged.\u003c\/p\u003e\n\u003ch2\u003eNothing at the Pump\u003c\/h2\u003e\n\u003cp\u003eFuel consumption stays where it was within any margin anybody can measure on a road. Claims in either direction should be treated with suspicion.\u003c\/p\u003e\n\u003ch2\u003eWhy Not Simply Adjust the Fuel Screw\u003c\/h2\u003e\n\u003cp\u003eBecause there is no fuel screw. Injection removed every mechanical adjustment a carburettor offered, and everything that used to be a screwdriver job is now a decision made in software.\u003c\/p\u003e\n\u003ch2\u003eA Single Curve, Not a Compromise\u003c\/h2\u003e\n\u003cp\u003eBecause the module is developed for one engine, the correction can be shaped for that engine's behaviour rather than averaged across a range of machines with different requirements.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eYamaha SR400 (2014–2016)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eJP MJ 008\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eJetPrime\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eCNC-milled Ergal 7075\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eYamaha SR400 (2014–2016)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInstallation\u003c\/th\u003e\n\u003ctd\u003ePlug-and-play, no wiring harness modifications required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"JetPrime","offers":[{"title":"Default Title","offer_id":53636827414794,"sku":"JP MJ 008","price":121.8,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/JP_MJ_008_00_04e9f274-72cb-4523-918a-cfca2c6cbcf6.png?v=1788728649","url":"https:\/\/inter-pace.com\/en-sm\/products\/jetprime-memjet-evo-power-module-yamaha-sr400-2014-jp-mj-008","provider":"Inter-Pace","version":"1.0","type":"link"}
