Unitronic UniFLEX Kit for 2.5TFSI EVO (DAZA)

Tired of trying to get that perfect ethanol mix? Want an easier way to get all the fun of running e85 without trying to do all the calculations? Unitronic hears you and they have a solution.

Introducing Unitronic’s UniFLEX Hardware Kit! This kit includes all the necessary components to make flex fuel integration as effortless as possible. The kit is comprised of their proprietary UniFLEX ethanol device, a genuine Continental ethanol content sensor that includes all the required fittings and harnesses, which allows for a true plug and play installation. 

The Unitronic FLEX enabled ECU Software Suite is sold as a $500 add-on for the 2.5TFSI EVO (DAZA) platform. After you purchase this add-on, Unitronic FLEX enabled files will be available for you up to your highest purchased ECU Software stage. So if you go from Stage 1 to Stage 3 ECU software, you WON'T need to purchase the FLEX add-on again in order to move up to one of our Stage 3 FLEX enabled ECU calibrations.

Ethanol is a renewable biofuel made from various plant materials, most notably corn. Since the growth, production, distillation and shipping are all mostly local, this fuel is often times lower in cost, making it more affordable than gasoline in some cases. You may have heard of Ethanol referred to as E85, which is a common term used to describe the fuel that contains up to 85% ethanol, hence E-85. The remaining concentration is usually gasoline and other additives. In reality, E85 can have varying concentrations of ethanol — aftermarket or race-grade E85 fuels will often contain 85% or higher concentrations of ethanol, but most of the pump-grade E85 that you’ll find at your local gas station will contain between 50% to 85% ethanol.

E85 fuel contains significantly more oxygen, burns cooler and has a much higher resistance to knock compared to conventional gasoline, which unlocks massive performance potential when combined with ECU Performance Software calibrated to maximize potential while using E85. The higher the concentration of ethanol, the more potent of a performance potential it has, as E85 with higher ethanol content allows for more ignition timing, etc.

At the heart of this, Unitronic’s UniFLEX Hardware Kit includes all the necessary components including plug-n-play wiring harnesses and accessories to make flex fuel integration as effortless as possible. Not only is it easy to install, Unitronic’s UniFLEX hardware also offers a multitude of additional benefits over any of the existing solutions on the market.

Unitronic’s UniFLEX Hardware Kit offers a multitude of benefits that make this a game changer:

• CAN integration of ethanol content data streamed to the ECM
• Plug-n-play harness! You won’t need to cut, splice, or do any ECM re-pinning
• Bluetooth connectivity with Unitronic’s UniE85 Manager App, meaning wireless connectivity with both iOS and Android     mobile devices.
• View ethanol content & fuel temperatures in real time with the UniE85 Manager app.
• Customize sensor calibration offsets and CAN integrations.
• Built in E85 mix calculator allows you to easily obtain any desired fuel blend.
• Over the air updates!

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

Unitronic has also implemented its own error handling routines, failsafes, and other safety mechanisms, triggering limp mode and custom fault codes, to protect against implausibilities, lost ethanol content sensor signal, and more.By popular demand, Unitronic has implemented its Wastegate Rattle Fix into all Stage 2 and Stage 3 FLEX enabled ECU calibrations. The wastegate is the mechanism that controls boost pressure, which in the case of the DAZA, is a vacuum controlled internal wastegate style. In factory trim, without any vacuum being applied to the wastegate actuator, like when driving at partial throttle, the wastegate flap sits in an open position, which is what causes the rattle sound to be audible. With Unitronic's Wastegate Rattle Fix, adjustments have been applied to the wastegate controls to hold the flap shut to eliminate the rattling sound.With the unique ability to blend mapping of timing, boost pressure, fueling, and so much more, Unitronic’s UniFLEX enabled ECU Performance Software and UniFLEX Hardware allows users to seamlessly transition from 0% to 85% ethanol content - in layman’s terms, 100% gasoline to 85% ethanol and anywhere in between, without needing to refresh. So E30, E70, E85, its ready for anything.

ADDITIONAL FEATURE ADDED - ROLLING ANTI LAG

By popular request, Unitronic is also proud to announce the addition of Rolling Anti Lag (RAL) into these new FLEX enabled calibrations.

FUNCTION USAGE: Turn cruise control ON, but not activated. Hold down cruise control stalk downwards (decrease speed, -), then go wide open throttle WOT. You can do this with your left fingers, while both hands are on the steering wheel with ease.

PRECONDITIONS FOR FUNCTION TO BE ACTIVE: 70degC coolant temp minimum threshold, more than 1000rpm engine speed, more than 30kph vehicle speed, and more than 45% throttle position. The function will be activated for 6 seconds maximum and can't be re-activated for 15 seconds refresh time.

This function is very hard on the engine and its components - IT IS NOT FOOL PROOF. It's easy to melt an engine to the ground with it. Use it wisely and at your own peril.

ADDITIONAL FEATURE ADDED - WASTEGATE RATTLE FIX

By popular demand, Unitronic has implemented its Wastegate Rattle Fix into all Stage 2 and Stage 3 FLEX enabled ECU calibrations. The wastegate is the mechanism that controls boost pressure, which in the case of the DAZA, is a vacuum controlled internal wastegate style. In factory trim, without any vacuum being applied to the wastegate actuator, like when driving at partial throttle, the wastegate flap sits in an open position, which is what causes the rattle sound to be audible. With Unitronic's Wastegate Rattle Fix, adjustments have been applied to the wastegate controls to hold the flap shut to eliminate the rattling sound.

ADDITIONAL FAILSAFES AND OTHER SAFETY MECHANISMS

Unitronic has also implemented its own error handling routines, failsafes, and other safety mechanisms, triggering limp mode and custom fault codes, to protect against implausibilities, lost ethanol content sensor signal, and more.

When a vehicle is flashed with a Unitronic FLEX enabled ECU calibration and cruise control is set to OFF, the factory power gauge will now show ethanol content percentage. Best of all, cruise control functionality remains unaffected and the power gauge works like stock, showing engine power when the cruise control is turned on and/or engaged. 

Unitronic’s E85 Manager application offers another way for you to wirelessly monitor ethanol content, calculate future gas/ethanol content blends depending on your performance goals and more while using your mobile device’s Bluetooth connection. Compatible with iOS and Android devices.

With extensive knowledge and experience working with the 2.5TFSI EVO (DAZA) platform over the years, Unitronic is confident that its new UniFLEX Hardware and Software offerings will perfectly compliment your vehicle. Thanks to the added convenience of being able to use gasoline or ethanol on-the-fly with mobile and CAN-bus integration, this highly anticipated package is sure to impress customers and enthusiasts all around the world.

So what are you waiting for? Get your Unitronic UniFLEX kit today and unlock the power of your 2.5TFSI EVO (DAZA).
