Unitronic UniFLEX Hardware Kit for 2.0TSI EVO4

Unitronic’s UniFLEX Hardware Kit includes the key components to make flex fuel integration as effortless as possible. Comprised of our proprietary UniFLEX ethanol device and all required harnesses, this kit allows for true plug and play installation. NOTE: This particular kit does not include an ethanol content sensor.

UniFLEX is also Bluetooth® enabled, allowing for wireless connectivity with iOS and Android mobile devices using the Unitronic UniE85 Manager App.

Unitronic E85 Manager is available for download on the App Store and Google Play Store.

NOTE: While this kit works with all 2.0TSI EVO4 vehicles, only the MK8 GTI is currently supported with FLEX enabled ECU Software. MK8 Golf R and 8Y S3 FLEX enabled software support is coming very soon.

NOTE: It is strongly recommended to use the UniFLEX Bracket for best experience.

NOTE ON SOFTWARE: Unitronic FLEX Enabled ECU Software is required and not included.

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.
