NRG Ops Bluetooth Evo X/RA Flex Fuel System

(3 customer reviews)


NRG Ops is happy to announce a Bluetooth flex fuel system for the 4B11T platform!
This kit is 100% plug and play, so installation is a breeze. With the ability for your ECU to see the ethanol content in the fuel and your ability to monitor it via your smart device, never worry about filling up again.

  • Fuel-It! flex fuel module with built-in Bluetooth.
  • Plug and play wiring for 4B11T equipped Evo X’s and Ralliarts.
  • OE GM/Continental flex fuel ethanol content sensor.
  • Stainless braided PTFE fuel line, with protective black coating. Pressure tested to ensure no leaks.
  • Spin-on EFI fittings. No more worries about clip on EFI fittings leaking or coming off.


  • Truly PnP. No cutting, soldering, splicing, etc. (EDM/AUDM will have to use an included add-a-fuse and pin the ECU).
    *Innovate/Zeitronix gauges are NOT plug-and-play and require wiring and mounting.*
  • Compatible with Tephra V3 ECU ROMs.
  • Ethanol content can be viewed via the Fuel-It! app for both iPhone and Android devices or logged via any Mode23 device.

Output voltage range: 0-5v (0% ethanol to 100% ethanol)

  1. Robert D

    Best plug and play kit there is on the market. Easy viewing with your phone on the Fuel It App ( yes it costs a few dollars, stop being cheap, you bought a $30k car). 100% plug and play, unlike anything else on the market. Will tell all my friends to buy just this kit, as I have seen the others on the market first hand.

  2. Carlos G

    Completely plug and play and works great! Having the app tell you the E content helps avoid setting up another gauge and running wires. Install is a breeze when you follow the simple instructions

  3. Rex

    Great product and convenient viewing of ethanol content.
