  • Expect 5-10 Business Day Turn around

Unitronic FLEX fuel enabled ECU Performance Software Calibrations are available for this platform allowing for seamless transitions between 100% gasoline to 85% ethanol and anything in between, without requiring an ECU reflash. This FLEX enabled Software is available for an additional fee and it covers all lower stages up until your highest purchased stage as well. UniFLEX Hardware is required in order to take advantage of these FLEX enabled calibrations. Please contact Unitronic or your local Authorized Dealer to learn more.

Unitronic Advanced Features (UAF) are also available for this platform. Thanks to proprietary ECU code, the Unitronic Advanced Features (UAF) Add-On gives unparalleled levels of control over Pops and Bangs, Launch Control Settings and Rolling Launch Control for true adjustability directly from the drivers seat.

• Immobilize Your Vehicle Instantly

  Enabling or disabling the UniLOCK is simple and can be donewithin seconds right from within the UAF Control appfor iOS and Android mobile devices. Once locked, youll see 222 on the factory torque gauge built into the instrument cluster indicating engine start is currently inhibited. When youre ready to drive again, simply open the UAF Control App and unlock within seconds.

• Feature Drop for Existing UAF (Advanced Feature) Clients

  UniLOCK is the latest Unitronic Advanced Feature (UAF) to drop and as such, is accessible on supported platforms for existing clients with UAF-enabled ECU tunesat no extra cost. Existing clients can reflash the ECU via UniCONNECT+ in order to get the latest UAF features into their ECU.

UNIFLEX:

Unitronic is proud to be the first to implement native, true, flex fuel code to the factory Bosch MG1CS163 ECU called UniFLEX. Unitronics 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 Unitronics UH012-FLA or UH013-FLA UniFLEX hardware kits.

When combined with Unitronics 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 drivers seat.

Exhaust Overrun (Pops and Bangs)

• Adjustable Drive Mode based PnB (Enabled in Dynamic & Performance modes)
• 3 levels of duration (Off, Short, Long)
• 3 levels of intensity (Low, Medium, High)

Adjustable Launch Control

• 8 Adjustable RPM Setpoints (4000-5400)
• 3 adjustable boost levels (Low, Medium, High)

Rolling Launch Control

• User adjustable RPM setpoint
• 3 adjustable boost levels (Low, Medium, High)
  

SFD filters must be unlocked before your ECU can be reflashed or data logs can be collected via the OBD2 port with UniCONNECT+. To learn more about SFD, check out or FAQ’sHERE.

Features

• Engineered with Strict Industry Standards
  With over 10 years of experience with Bosch and Siemens engine management systems and calibrations, Unitronic is able to utilize its expertise, industry leading tools and equipment to ensure an optimal calibration; delivering maximum performance, while maintaining complete OEM-like reliability and drivability.
• Extensively Tested Under Various Driving Conditions
  Development begins using Unitronics in-house Maha Chassis dyno housed in an environmentally controlled cell; closely monitoring a plethora of operational data, utilizing industry leading calibration tools and resources. Beta calibrations are then tested in street and track scenarios, using multiple cars under various driving conditions. This engine calibration strategy ensures Unitronic Performance Software delivers maximum performance, OEM-like drivability and reliability anywhere in the world. Unitronic Performance Software is only released to its Clients once development is thoroughly completed in accordance to Unitronics strict standards.
• Factory Safety Limiters Retained
  OEM fail safes are retained within the ECU calibration. Close monitoring of all operation parameters ensures that engine operation stays within factory components limits, resulting in reliability.
• Optimized Responsiveness, Smoothness, Drivability, and Comfort
  Unitronics ECU calibrations are engineered to improve engine response and reduce low-end lag. Unitronics Performance Software has gained worldwide recognition and is well known for its broad powerband, with smooth power delivery, maximizing responsiveness and area under the curve, under normal and hard acceleration.
• Optimized Maximum Output
  Unitronics ECU Calibrators deliver the maximum power output while staying within the operational limits of the factory engine and drivetrain components. Specifically, this results in the highest engine performance without sacrificing the reliability of the engine, turbocharger, or other engine and drivetrain components.
• Power Delivery Perfectly Optimized Throughout the Power Band
  Aligned with the OEM strategy, the calibration is designed to offer a large flat torque plateau to provide a smooth and linear power band. Maximum torque output is achieved sooner and maintained longer which creates a broader torque plateau and greater area under the curve. This results in an improved acceleration and optimal engine operation.
• Improved Fuel Efficiency
  Optimized timing and injection in cruising condition allows for an improved fuel efficiency, under normalized driving conditions.
• Ignition Timing Precisely Calibrated for Higher Octane Fuel
  Engine calibration optimized to take advantage of higher fuel quality to extract maximum energy from the combustion. Therefore, when using a higher octane fuel, more power and better fuel efficiency will be achieved.
• Speed Governor Removed
  Vehicle speed limiter within ECU is removed. (Subject to transmission rotational speed limit.)
