Delicious Tuning CAN Gateway Flex Fuel Kit – Subaru WRX (2015–2021)

The Delicious Tuning CAN Gateway Flex Fuel Kit is a seamless, plug-and-play E85 solution designed specifically for the Subaru WRX (2015–2021). Built with FutureFlex Technology, this system integrates directly with the latest COBB NexGen OTS maps and Green Speed-compliant ProTunes while retaining full OEM sensor functionality.

With native CAN communication, ethanol content data—and optional fuel pressure data—can be viewed directly on the COBB Accessport screen and recorded in datalogs. Installation is fully reversible and requires only a few simple connections in the engine bay, along with a pass-through CAN connector for clean ECU communication. No changes to the factory fuel rail or regulator are required.

The CAN Gateway Flex Fuel System accurately measures ethanol content and sends precise data to the ECU. The ECU then dynamically adjusts air/fuel ratios, ignition timing, boost targets, cam angles, traction control, and more based on the ethanol percentage—ensuring smooth and safe operation whether running pump 98, E85, or any blend in between.
