If you're running E85 and/or plan to run port injection in your hi-power S58, you need this kit!

Our new Plug & Play Hi-Flow Canbus Integrated Flex Fuel Kit offers a few new features:

• In addition to knowing your exact ethanol content in real-time via the JB4 mobile app, the ethanol content is also sent to the ECU for those of you running a flex fuel flash from MHD, ECUtek, BM3, and others.  Note:  If you are running BM3, your harness will require a different connection point.  Please reference this install guide for those connections.  https://youtu.be/ldptxK0fQrY?si=MLwZmPgfPjP5sHr5
