eFlexFuel Kit Chevy Silverado 4.8 - eFlexFuel Technology

eFlexPlus

Install eFlexPlus, fill up with E85, and Drive – that’s it! It has never been easier (or safer) to harness the performance of E85:

  • Drive on E85, Gasoline, or any blend of the two
  • Fully Automatic: No tuning, changing maps, or adjustments required
  • Choose between Eco, Dynamic, & Sport Driving Modes, adjust cold-start fueling, monitor Ethanol content and Duty Cycle, and more via smartphone with our eFlexApp
  • “Under-the-hood” installation that doesn’t touch your factory ECU, OBD, or trigger a Check Engine Light
  • We verify your vehicle’s E85 compatibility, including fuel injectors, fuel pump, fuel lines, and any modifications done
  • Everything needed to run E85 & DIY install is included
  • Make more power, lower operating temperatures, and reduce emissions on E85!

The eFlexPlus E85 flex fuel kit automatically adjusts and optimizes fueling based on the E85 mix in your tank, eliminating knock and maximizing engine performance in the process. eFlexPlus is the easiest way to convert your vehicle to a true flex fuel, E85-or-Gasoline capable vehicle. You will make more power with our eFlexPlus kit, however for those looking to fine tune their fueling, we recommend taking a look at our eFlexPro kit.

eFlexPro2

Simply install the eFlexPro 2 and you're ready to start pumping E85 into your tank to make more HP/TQ. You'll see significant power gains running our default driving modes, but take things to another level with safe DIY tuning to optimize Ethanol performance for your specific vehicle.

  • The eFlexPro includes all eFlexPlus features in addition to the following Pro-only features
  • Improved fuel control capabilities
  • Upgraded Control Unit hardware
  • Upgraded wiring harness with two optional 0-5V Analog Inputs
  • Patent pending Virtual Load Sensor - no tapping into an external load sensor required!
  • Connect your aftermarket wideband sensor to datalog and create E85 specific fueling maps
  • Detailed Ethanol AFR tuning via our eFlexTuner Windows software


Have an aftermarket wideband?

If YES, we strongly recommend our eFlexPro system. Your aftermarket wideband can be connected directly into the eFlexPro harness to fine-tune fueling and dial in ethanol AFR’s with our free eFlexTuner Windows software. Select the eFlexPro drop-down to learn more.

Vehicles with upgraded injectors and/or big power adders (aftermarket forced induction, cams, etc.) are recommended to go with our eflexpro kit for detailed fine-tuning and fueling capabilities.
