Do I need to tune my vehicle?

  • Updated
  • No — no special tuning is required. Your vehicle’s stock ECU and factory tune work perfectly with an eFlexFuel kit.
  • eFlexFuel kits are designed to extend your vehicle’s fueling capabilities while working seamlessly with the original setup. If your vehicle runs properly on regular gasoline, it will be ready to run E85 once the eFlexFuel kit is installed.
