Description
The Unitronic UniFLEX Hardware Kit (with Sensor) for 2.5TFSI EVO is a plug-and-play flex fuel solution engineered to provide seamless ethanol integration for Audi RS3 and TT RS Quattro vehicles. Equipped with a genuine Continental ethanol content sensor, this kit allows precise ethanol content monitoring and control for fuel blends up to 85% (E85), delivering optimal performance, efficiency, and reliability.
Designed for convenience, the UniFLEX Hardware Kit includes all required harnesses, fittings, and proprietary UniFLEX ethanol device for effortless installation. Bluetooth® connectivity via the Unitronic UniE85 Manager App (iOS/Android) enables real-time monitoring of ethanol content and fuel temperature, as well as calibration adjustments and CAN integration for advanced control.
When paired with Unitronic FLEX-enabled ECU software, this system allows drivers to blend timing, boost, and fueling maps dynamically, transitioning from 0% to 85% ethanol or 100% gasoline to E85 without ECU reflashing. Over-the-air (OTA) updates ensure continued compatibility and functionality.
