Run E85 straight from the pump without having to worry about manually calculating your ethanol content percentage! With the AMS CAN Bus 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 Nissan. This flex-fuel system is truly set-it-and-forget-it — once installed and tuned, no further adjustments are needed. With CAN bus integration, it also provides three additional analog inputs for monitoring and failsafe setting, ensuring optimal performance and reliability. The complete kit includes the AMS CAN bus box, ethanol sensor, braided fuel lines, hardware, and a plug & play wiring harness for an easy and quick install. This kit is also directly compatible with EcuTek software to provide a seamless flex fuel calibration solution.

Engineered To Be The Best

AMS Performance is an engineering company first. We have built our decades-long 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 plug-n-play harness, braided fuel lines, and AN fitting connections. Where others use cheap 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 AMS Performance Nissan GTR CAN Bus Flex Fuel Kit are a number of brackets which are designed to secure the various components within the kit to stable locations. Where other kits leave items like the content sensor unsecured to move around in the engine bay, we provide robust 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.

Factory CAN Bus Integration

With this new and improved Can Bus Flex Fuel Kit, our team of engineers have come up with a solution to integrate with the factory CAN bus protocol. This allows for seamless communication with the vehicle’s ECU rather than a piggybacked or hijacked connection from an existing engine system. In addition to this, there are three additional 0-5v analog inputs available through our proprietary CAN bus box. With our CAN bus integration, your tuner can set failsafes that trigger if a sensor detects a reading outside the safe range. These additional analog inputs can be used for monitoring coolant pressure, fuel pressure, exhaust backpressure, crankcase pressure, and various other aftermarket 0-5v analog sensors, seamlessly integrating them into the CAN bus network. This provides enhanced safety measures that were not previously available to your tuner. Through software calibration, individual failsafes can be programmed to activate when pressure is too high or too low, offering an extra layer of protection for your engine, even in extreme conditions. Our team is always looking for ways to improve our products and adapt to stay on top of the latest changes in the industry. These additional safety features give you peace of mind when using the AMS Performance Nissan GTR CAN Bus Flex Fuel Kit, so you can simply enjoy driving your E85 tuned GTR.
