The core of Unitronic's UniFLEX Hardware Kit comprises a comprehensive set of essential components, complete with user-friendly plug-and-play wiring harnesses and accessories, designed to streamline the process of integrating flex fuel. Installation is not only straightforward but also brings many advantages that outshine any currently available solutions.

Note this kit does NOT come with an Ethanol Sensor! 

Ethanol, a sustainable biofuel, is derived from various plant sources, with corn being one of the most prominent. This eco-friendly fuel is often more cost-effective than gasoline, thanks to its predominantly local supply chain encompassing growth, production, distillation, and distribution. You may be familiar with Ethanol, referred to as E85, a common designation for fuel consisting of up to 85% ethanol (hence the "E-85" moniker), with the remaining composition typically comprising gasoline and additives. However, it's important to note that E85 can have variable ethanol concentrations. While specialty or high-performance E85 fuels often contain 85% or more ethanol, the E85 commonly available at local gas stations generally falls within the 50% to 85% ethanol range.

E85 fuel stands out due to its notably higher oxygen content, cooler combustion characteristics, and superior resistance to engine knocking when compared to traditional gasoline. This unique combination of properties unlocks significant performance potential, especially when paired with Engine Control Unit (ECU) Performance Software specifically tuned to harness the advantages of E85. Notably, the more significant the ethanol concentration, the more substantial the performance potential, as E85 with a higher ethanol content facilitates advanced ignition timing and other enhancements.

To facilitate the installation of the UniFLEX device within the engine bay, Unitronic specifically designed an aluminum mounting bracket that features numerous mounting points, allowing customers to install their UniFLEX device in vertical or horizontal orientation on their MQB chassis vehicles.

Unitronic's E85 Manager allows you to wirelessly view your vehicle’s current ethanol content and integrate this fuel composition data over your vehicle's CAN-BUS when combined with the UniFLEX module, an Ethanol Content Sensor and ECU Performance Software calibrated to add Flex Fuel functionality while using your mobile device's Bluetooth connection.

The included E85 Mix Calculator allows you to calculate current and future gas/ethanol content blends to ensure you can achieve your target ethanol content using your fuel tank size, current fuel level, current ethanol content, target ethanol content, and more!

• Customize Sensor Calibration Offsets and CAN integrations**

• E85 Mix Calculator

• OTA Updates

**Even if you’re not using UniFLEX with Unitronic’s Flex-enabled ECU Performance Software calibrations, customizable CAN integrations are available for use with other tuner’s ECU calibrations, negating the need to run additional wires to the ECU, through the firewall into the passenger compartment, or the need to keep additional accessories connected to the vehicle’s OBD2 port. We encourage you and your tuner to learn more about the customizable CAN integrations available with UniFLEX!
