Unitronic is proud to be the first to implement native, true, flex fuel code to the factory Bosch MG1CS163 ECU called UniFLEX. Unitronic’s UniFLEX Hardware allows for a plug and play installation through its proprietary UniFLEX Module and a genuine Continental Ethanol Sensor with required fittings and harnesses.

NOTE: The 8Y RS3 uses Unitronic’s UH012-FLA or UH013-FLA UniFLEX hardware kits.

When combined with Unitronic’s UniFLEX-enabled Performance Software Add-On, the factory Bosch MG1CS163 ECU receives ethanol content over the CAN-bus and utilizes this fuel composition data to blend mapping of timing, boost pressure, fueling, and much more completely on-the-fly. This allows for seamless transitions from 100% gasoline to 85% ethanol and anywhere in between, without needing an ECU reflash.

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

Adding even more to the magnitude of this project, Unitronic is proud to introduce its Advanced Features. Thanks to the proprietary ECU code, the Unitronic Advanced Features (UAF) Add-On gives unparalleled levels of control for true adjustability directly from the driver’s seat.
