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.
  • Our new Hi-Flow kit includes 3/8" (6an) stainless steel braided lines with our exclusive custom billet fittings
  • Our new custom fitting now makes adding port injection easier than ever.  Simply remove the 1/8" NPT fitting and add one of our optional port injection lines.

This complete plug and play kit to installs in 15- 30 minutes.

Our CANbus ECA is compatible with JB4 as well as flash only applications like MHD, BM3, and EcuTek that read the standard 0xEC flex fuel CANbus address format .

     *We have also made it optional  to purchase all the items ala-cart should you choose but for the kit to work it must include the Fuel Lines, Ethanol Sensor, and CANflex analyzer.

    *Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated.
