Show original supplier description
The Unitronic UniFLEX Hardware Kit & bracket provides essential components for seamless flex fuel integration. This kit enables true plug-and-play installation with its proprietary UniFLEX ethanol device and all required harnesses. A key feature is the Bluetooth connectivity, allowing wireless control and monitoring through the Unitronic UniE85 Manager App for iOS and Android devices. The app enables users to view ethanol content, utilize a fuel blend calculator, customize sensor calibration offsets, and receive over-the-air (OTA) updates. This hardware kit requires Unitronic FLEX enabled ECU software, which is sold separately and incurs an additional fee. Compatible software includes Stage 1, Stage 1+, Stage 2, and Stage 3 FLEX calibrations, designed for various octane levels and E85 blends, including specific calibrations for TTE700 and TTE777 turbochargers. The software also features Rolling Anti Lag (RAL) and a Wastegate Rattle Fix. This product is specifically designed for the 2017-2020 Audi RS 3 2.5TFSI EVO and the 2018-2022 Audi TT RS 2.5TFSI EVO. It is explicitly stated that this kit is NOT FOR THE DNWA ENGINE CODE.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout.
