The 8Y RS3 was one of the first platforms to arrive equipped with the new Bosch® H80 MG1CS163 ECU hardware, which is a highly sophisticated controller, that introduced new challenges in not only finding a solution to gain access to reflash the new ECU hardware, but also get oriented with the new strategies found in this new MG1CS163 ECU type, while simultaneously introducing new innovation features and solutions.

Unitronic Software Engineers quickly developed an ECU unlock solution, but due to the unique nature of these new H80 MG1 ECUs, Unitronic requires ECUs to be sent to its Headquarters for unlock operations to be performed. With over 20 years of experience in this market, it was evident that some customers would not want any downtime associated with the ECU unlocks, so Unitronic is happy to offer three options regarding the ECU Unlock, in efforts to offer a variety that will suit everyone's preferences.

UNIFLEX:

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.

UNITRONIC ADVANCED FEATURES (UAF):

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.
