AMS Performance Nissan Z CAN Bus Flex Fuel Kit w/ Fuel Filter

Take the guesswork out of running ethanol-based fuels with the AMS Performance CAN Bus Flex Fuel Kit for the Nissan Z — now bundled with our high-performance in-line fuel filter for complete protection and reliability. This all-in-one solution lets you run gasoline, E85, or any blend in between (0–100% ethanol), while the system automatically adjusts fueling, boost, and timing in real-time based on ethanol content. No manual calculations or switching maps are required — just fuel up and drive. The kit is fully compatible with EcuTek tuning software, making calibration simple and seamless.

Ethanol’s cleaning properties can dislodge years of sediment from fuel tanks and lines, potentially causing damage to injectors or internal components. That’s why we include our AMS in-line fuel filter — a critical safeguard designed specifically for the VR30 engine. It helps prevent common OEM fuel system failures often seen with ethanol use, especially at higher blends like E50 or E85. With integrated CAN bus support, the system also provides three analog inputs for additional sensors or failsafe programming. Everything you need is included: AMS CAN bus box, ethanol sensor, fuel filter, braided fuel lines, plug-and-play wiring harness, and hardware. This is the ultimate set-it-and-forget-it flex fuel upgrade — engineered for power, protection, and peace of mind.

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 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 AMS Performance Nissan Z CAN Bus 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 and CNC machined anodized aluminum 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.

Performance Filtration

We designed this custom filter housing for use specifically on the RZ34 Nissan Z with VR30 engine so that it can be bolted directly to the vehicle’s chassis in OEM bolt locations. Other kits on the market or universal DIY options use an unsecured generic housing, but our design allows us to integrate a mounting solution so you can securely mount the filter unit.  This is a safety feature as much as it is an aesthetic one, as it 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 Z CAN Bus Flex Fuel Kit, so you can simply enjoy driving your E85 tuned Z.
