Ethanol Blend Add-On

The Ethanol Blend Add-On provides a revision to your existing tune if you decide to switch to running an ethanol blend (E30, E40, or full E85) after your original calibration. 

How It Works

• Designed for customers who already have an active or completed eTune with us.

• Once you’re ready to run ethanol or E85, purchase this add-on and provide your updated fuel setup.

• Includes revised calibration and datalog-driven adjustments for the blend or full E85 you plan to run.

• Customer must provide accurate ethanol content (tested with an ethanol tester or sensor) to ensure safe tuning.

Important Notes

• Applies only to revisions for ethanol blends or E85 on an existing tune purchased from us.

• Vehicle must be mechanically sound with fuel system components capable of supporting ethanol/E85.

• If additional supporting mods (fuel pump, injectors, turbo, etc.) are added at the same time, a new tune package may be required.

• Non-refundable once the revised calibration file has been sent.
