Its fuelling is about managing an engine that produces more torque than the chassis wants.\u003c\/p\u003e\n\u003ch2\u003eLoad and Revs\u003c\/h2\u003e\n\u003cp\u003eThose two axes define every operating point an engine ever reaches. A map with enough cells describes the whole of it, which is what complete management of the fuel map actually means.\u003c\/p\u003e\n\u003ch2\u003eResolution Matters\u003c\/h2\u003e\n\u003cp\u003eA map with too few cells forces the unit to interpolate across large gaps, and the engine feels it. Enough resolution is what makes small, local corrections possible at all.\u003c\/p\u003e\n\u003ch2\u003eFull Load Is Easier\u003c\/h2\u003e\n\u003cp\u003eWide open throttle is one line through the map and a dyno reads it quickly. It is also the region a road rider visits least, which is worth remembering before spending a day on it.\u003c\/p\u003e\n\u003ch2\u003eThe Standard Sensor Is Not Enough\u003c\/h2\u003e\n\u003cp\u003eA narrowband oxygen sensor only reports near stoichiometric. It cannot tell you what the mixture is doing at full load, which is exactly where you need to know.\u003c\/p\u003e\n\u003ch2\u003eNo Subscription\u003c\/h2\u003e\n\u003cp\u003eThe software is supplied, the maps belong to the owner and nothing is rented. In a market moving the other way that is worth saying out loud.\u003c\/p\u003e\n\u003ch2\u003eOn a Road Bike\u003c\/h2\u003e\n\u003cp\u003eWorth it if the motorcycle is genuinely modified and the owner enjoys the work. Otherwise the preset module reaches most of the benefit for less money and no evenings.\u003c\/p\u003e\n\u003ch2\u003eOn a Twin\u003c\/h2\u003e\n\u003cp\u003eWidely spaced firing events make mixture errors easy to feel. Owners of large twins usually notice the improvement from careful mapping before anybody else does.\u003c\/p\u003e\n\u003ch2\u003eWhen It Is Finished\u003c\/h2\u003e\n\u003cp\u003eWhen another session produces no change you can measure and none you can feel. Beyond that point the work is a hobby rather than an improvement, which is a perfectly good reason to continue.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eYamaha V-MAX (2009–2016)\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 CJP 084H\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 V-MAX (2009–2016)\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":53637212340490,"sku":"JP CJP 084H","price":200.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/JP_CJP_084H_00_1df0a26e-66e7-4ea2-9174-37a1a829d21e.png?v=1788760908","url":"https:\/\/inter-pace.com\/en-na\/products\/jetprime-programmable-control-unit-yamaha-v-max-2009-jp-cjp-084h","provider":"Inter-Pace","version":"1.0","type":"link"}
