Stop Guessing. Start Knowing Your Exact Ethanol Content.
Running E85 on your turbocharged vehicle? Ethanol content at the E85 pump can vary from E50 to E85 or higher depending on season and station. Regular premium gas can have up to 10% ethanol at some stations. No more calculating gallons at the pump and guessing ethanol percentage. Just open the app and know.
Key Features
• Real-time ethanol content monitoring via Bluetooth
• Displays exact ethanol percentage (E-content) in the Fuel-It! or JB4 app
• 0–5V analog output for JB4 or flash tuning integration
• Genuine Continental ethanol sensor for OEM-grade accuracy
• Plug and play fuel line integration
• Ethanol safe PTFE fuel lines and fittings
• Installs in approximately 30 minutes
• No cutting or permanent modification required
Why You Need an Ethanol Sensor
E85 pumps rarely dispense true E85. Seasonal blends can drop into the E50 range without notice. If you’re tuning for ethanol, this matters.
With this kit you can
• Dial in your exact E85 blend every fill-up
• Avoid running too much ethanol on a pump gas map
• Maximize timing and boost safely on ethanol maps
• Maintain consistent performance at the track
• Protect your engine from unknown fuel mixtures
The Bottom Line
If you’re running E85, a flex fuel sensor isn’t optional, it’s essential.
Power, consistency, and safety all start with knowing exactly what’s in your tank.
