Stop Guessing. Start Knowing Your Exact Ethanol Content.

Running E85 on your turbocharged 3.4L Toyota? 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.

Why You Need an Ethanol Sensor

E85 pumps rarely dispense true E85. Seasonal blends can drop into the E50 range without notice. If youre 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 youre running E85, a flex fuel sensor isnt optional, its essential.

Power, consistency, and safety all start with knowing exactly whats in your tank.
