That's also why model selection matters: an adapter for the wrong platform simply won't talk to your car, so pick your exact model from the variant list before ordering. Installation is three screws into the rear of the quick release plus the harness connection, well within reach of a home installer who already has an SCX in the car. If your model variant ships with a fuse tap, it's there because that platform needs a switched power source for the adapter.\u003c\/p\u003e\n\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x OEM Adapter\u003c\/li\u003e\n\u003cli\u003e1x Adapter Harness\u003c\/li\u003e\n\u003cli\u003e3x Installation screws\u003c\/li\u003e\n\u003cli\u003e1x Fuse tap (select model variants only)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNC MX-5 (MT)\u003c\/li\u003e\n\u003cli\u003eNC MX-5 (AT)\u003c\/li\u003e\n\u003cli\u003eND MX-5 (MT)\u003c\/li\u003e\n\u003cli\u003eND MX-5 (AT)\u003c\/li\u003e\n\u003cli\u003eRX-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Zestek Racing USA","offers":[{"title":"NC MX-5 (MT)","offer_id":43549871046723,"sku":null,"price":249.99,"currency_code":"USD","in_stock":true},{"title":"NC MX-5 (AT)","offer_id":43549871079491,"sku":null,"price":249.99,"currency_code":"USD","in_stock":true},{"title":"ND MX-5 (MT)","offer_id":43549871112259,"sku":null,"price":249.99,"currency_code":"USD","in_stock":true},{"title":"ND MX-5 (AT)","offer_id":43549871145027,"sku":null,"price":249.99,"currency_code":"USD","in_stock":true},{"title":"RX-8","offer_id":43549871177795,"sku":null,"price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/edited_orignial_1_to_1_crop_AI_TEST_4babe301-2aa1-4645-a1fe-a900aa893cc7.jpg?v=1785865590"},{"product_id":"mazda-scx-oem-adapter-harness","title":"Mazda - SCX OEM Adapter Harness","description":"\u003cp\u003e\u003cstrong\u003eA spare harness beats a scratched weekend.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eOne pinched wire in the column and your SCX loses its CAN link to the car.

It is the boring, repeatable fueling every serious build needs.\u003c\/p\u003e \u003ch3\u003eWhat You'll Feel\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFaster dyno sessions, because accurate injector data means less time chasing fuel trims\u003c\/li\u003e\n\u003cli\u003eFuel trims that stay put season to season instead of drifting with the weather\u003c\/li\u003e\n\u003cli\u003eSteady AFRs when boost climbs, no lean spikes at the top of the pull\u003c\/li\u003e\n\u003cli\u003eHeadroom to grow the build without touching the fuel system again\u003c\/li\u003e\n\u003cli\u003eCrisp part-throttle response instead of the surge and stumble big injectors are known for\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNominal flow rate: 2600cc\/min at 3.0 bar (43.5 psi)\u003c\/li\u003e\n\u003cli\u003eMaximum differential fuel pressure: 9.0 bar (130.5 psi), requires a minimum of 11 volts\u003c\/li\u003e\n\u003cli\u003eCompatible with methanol, ethanol, and all known hydrocarbon fuels\u003c\/li\u003e\n\u003cli\u003eNot compatible with ethers (MTBE, ETBE, TAME) or nitromethane\u003c\/li\u003e\n\u003cli\u003eUSCAR electrical connector\u003c\/li\u003e\n\u003cli\u003eConfiguration: 60mm body, 11mm adapter top, Denso lower cushion\u003c\/li\u003e\n\u003cli\u003eSupplied as a flow-matched set with Dual Slope Matching for consistent delivery at low pulse widths\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eThe Details\u003c\/h3\u003e\u003cp\u003eThe ID2600-XDS is the biggest injector to come out of the Injector Dynamics and Bosch Motorsport partnership, developed specifically for liquid fuels with corrosion resistant internals for long term ethanol and methanol use. Dual Slope Matching is the difference maker here: matched on static flow alone, injectors this size deviate around plus or minus 5.1 percent at low pulse widths, while Dual Slope Matching brings that down to plus or minus 1.4 percent. One thing to know going in: it needs a minimum of 11 volts and is not compatible with ethers like MTBE or with nitromethane. Every set ships flow matched, and Injector Dynamics publishes full characterization data, including slope, offset (dead time) versus voltage and pressure, and short pulse width behavior, so your tuner can load real numbers instead of chasing fuel trims across the map. Accurate dead times are what make large injectors behave at idle and cruise, and they are the reason these tune quickly and stay tuned. This configuration uses machined top adapters (already fitted) to suit the rail height listed above. The Denso lower cushion seats these in Denso-style manifold bores. If your harness does not have USCAR plugs, plug and play connector adapters are available separately, no cutting or soldering required.\u003c\/p\u003e \u003ch3\u003eKit Includes\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1 - Set of ID2600-XDS Injectors\u003c\/li\u003e\u003c\/ul\u003e \u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2003-2011 Mazda RX-8*\u003c\/li\u003e\n\u003cli\u003e*Secondaries Only\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Injector Dynamics","offers":[{"title":"Default Title","offer_id":43625775726659,"sku":"IDY 2600.60.11.D.2","price":796.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/injector-dynamics-idy-2600-60-11-d-2-13607880360006.jpg?v=1785794092"}],"url":"https:\/\/www.tunedbyshawn.com\/collections\/rx-8.oembed","provider":"Tuned by Shawn","version":"1.0","type":"link"}
