Description Run E85 straight from the pump without having to worry about manually calculating your ethanol content percentage! With the Nissan Z Flex Fuel Kit you can run gasoline, E85, or any mixture of gas and ethanol with a content rating from 0 to 100% ethanol. Our flex fuel system’s ethanol sensor and electronics instruct your vehicle’s ECU on how to adjust parameters like fueling, boost, and timing to produce the most power possible for a given fuel or mixture of fuels. These adjustments happen seamlessly in the background of your flex fuel tune allowing you to be flexible with what fuel you utilize in your Z. Featuring a Zeitronix CAN Bus content analyzer to directly integrate with the OEM vehicle control systems, this is a set-it-and-forget-it flex fuel system that requires no adjustment once installed and tuned. Our AMS Calibration team has spent countless hours working with EcuTek on their flex fuel development program, meaning the AMS Nissan Z Flex Fuel Kit is now directly compatible with EcuTek calibration software, making tuning a breeze. AMS Performance is an engineering company first. We have built our 20+ year reputation as a leading motorsports aftermarket component manufacturer by creating the highest performing parts through a focused engineering approach to design. This design method allows us to include features not found in any other kits on the market, including a motorsports quality braided fuel lines, and quick connect AN fitting connections. Where others use plastic fittings, low grade rubber fuel hose, and leak prone clamps, we have put together a system that uses the highest quality materials for years of trouble free operation. Also included in the Nissan Z Flex Fuel Kit are a number of brackets which are designed to secure the various fuel lines and components within the kit to OEM bolt locations. Where other kits leave items like the content sensor unsecured to move around in the engine bay, we provide stainless steel brackets to mount these pieces. This is done to prevent any possibility of damage to the lines from continuously rubbing on other components, as well as to prevent fittings from possibly loosening over time, causing a dangerous fuel leak.
