Why You Need an Ethanol Sensor in your Bronco?
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.
