Peak Performance Anywhere You Go

With the unique ability to blend mapping of timing, boost pressure, fueling and much more, Unitronic's FLEX enabled ECU Performance Software and UniFLEX Hardware allows users to seamlessly transition from 0% to 85% ethanol content — or said another way, 100% gasoline to 85% ethanol and anywhere in between, without needing an ECU reflash.

Ethanol Monitoring Within Your Digital Dash

When a vehicle is flashed with a Unitronic FLEX enabled ECU calibration and cruise control is set to the OFF position, the factory power gauge will now show ethanol content percentage. Best of all, cruise control functionality remains unaffected and the power gauge works like stock, showing engine power when the cruise control is turned on and/or engaged.

Unitronic E85 Manager iOS/Android Application

Unitronic's E85 Manager application offers another way for you to wirelessly monitor ethanol content, calculate future gas/ethanol content blends depending on your performance goals and more while using your mobile device's Bluetooth connection. Compatible with iOS and Android devices.
