Unitronic UniFLEX ECU Software - VW/Audi / Mk8 / 8Y / Golf R / S3

Unitronic Stage 1+ E85 Performance Software is precisely calibrated for use with E60-E85 ethanol fuel blends and provides huge power gains over stock while maintaining an OEM-like driving experience with exceptional reliability.

Start/Stop Memory is now enabled and High-Speed Data Logging is also available via UniCONNECT+ for the SIMOS 19.6 ECU.

NOTE: E85 calibrations are not flex fuel calibrations by default, therefore, when using an E85 ECU calibration, the engine is only designed to operate on E85 blends from E60-E85.

Using an E85 calibration with pump gasoline or race gas may result in engine damage.

Unitronic strongly recommends the use of UniFLEX or an Ethanol Content Analyzer, to ensure Ethanol content levels are within the permissible range. When switching between gasoline to ethanol, please use Unitronic’s fuel conversion guide here.

Unitronic Stage 1 TCU Performance Software, Unitronic MPI Upgrade Kit, Unitronic Intake with Air Duct and Unitronic Intercooler are required to achieve advertised power figures.

Performance Software for your ECU Box Code is subject to availability.

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. UniFLEX calibrations also include several new features such as Rolling Launch Control (RLC) and Advanced Thermal Management. Learn more here. 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.

• Optimized Responsiveness, Smoothness, Drivability, and Comfort
  Unitronic’s ECU calibrations are engineered to improve engine response and reduce low-end lag. Unitronic’s 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.
  
  
• 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.
  
  
• Start/Stop Memory Enabled
  Unitronic ECU calibrations now include Start/Stop Memory, which enables the vehicle to now remember the last set position. This feature will be rolled out for all tuned files for the MK8 GTI / R, 8Y S3 and more platforms soon.
  
  
• Rolling Launch Control (RLC) (UniFLEX Exclusive)
  By popular request, Unitronic is proud to announce the addition of Rolling Launch Control into its new UniFLEX calibrations for DSG vehicles. MQ350 (6MT) vehicle support is coming soon. See activation instructions here.
  
  
• Advanced Thermal Management (UniFLEX Exclusive)
  Factory strategies include a tendency to favor higher operating temperatures for targeting maximum efficiency. Unitronic has developed and implemented its Advanced Thermal Management to target lower coolant temperatures based on the current drive mode selected by the driver.
  
  
• High-Speed Data Logging via UniCONNECT+
  For customers looking to gain greater insights about their vehicle's true performance, High Speed Data Logging for the SIMOS 19.6 ECU is now built in to the latest UniCONNECT+ Application allowing enthusiasts to collect high speed data logs at the a much higher resolution than any other publicly available tools can offer.
  
  
• Optimized Maximum Output
  Unitronic’s 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.
  
  
• 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.
  
  
• 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.
  
  
• Speed Governor Removed
  Vehicle speed limiter within ECU is removed. (Subject to transmission rotational speed limit.)
  
  
• Improved Fuel Efficiency
  Optimized timing and injection in cruising condition allows for an improved fuel efficiency, under normalized driving conditions.
  
  
• 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 Unitronic’s 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 Unitronic’s strict standards.
