Description
Run E85 without limits — no switching maps, no guessing ethanol content, just pure performance. The AMS Performance CAN Bus Flex Fuel Kit for the Nissan Z (RZ34) is your one-and-done solution for safely running ethanol blends from 0 to 100%. Whether you’re filling up with pump gas, E50, or full E85, the system auto-adjusts timing, boost, and fueling in real-time — giving you maximum power and reliability without lifting a finger.
This kit features true CAN bus integration and works seamlessly with EcuTek tuning software, making calibration simple and powerful. It even includes three additional 0-5v analog inputs so you can add fail-safes and monitor vital pressures like fuel, coolant, or crankcase — giving tuners the tools they need to protect your engine at any power level.
The plug-and-play wiring harness, braided -6AN fuel lines, and race-grade fittings make installation clean and easy. Built with CNC-machined anodized brackets, the entire setup bolts directly to OEM mounting points for a rock-solid fit and OEM-level finish. No zip ties, no loose sensors, no shortcuts.
AMS Performance took the guesswork out of ethanol tuning — this kit is the ultimate “set it and forget it” upgrade for any boosted Nissan Z.
