  • Engineered with Strict Industry Standards: With over 10 years of experience in Bosch and Siemens engine management calibration, Unitronic is able to utilized its industry leading tools and equipment to assure a calibration
  • Extensively Tested Under Various Driving Conditions: Development begins using its in-house engine dyno housed in an environmentally controlled cell; closely monitoring a plethora of operational data, utilizing industry leading calibration tools and resources. Additional validation and results comparison are completed using its in-house Maha Chassis dyno as a second step of product development. Beta calibrations are then tested in race and street scenarios, using multiple cars throughout the world 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.
  • 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 an OEM-like drivability and reliability.
  • Engine Temperature Protection (Rev Limit based on Engine Coolant Temperature): Engine speed limit protection active under warm-up to prevent potential damage when coolant temperature is not within operation range.
  • Optimized Responsiveness and Drivability: Professionally calibrated to improve engine response and reduce drive-by-wire lag. Optimized torque curve for more low end torque and faster turbo spool.
  • Optimized Smoothness and Driving Comfort: Due to the large flat torque curve, the calibration offers a smooth operation under normal and hard acceleration. This results in linear acceleration with constant torque without low end torque peak that will cause loss of traction and uncontrollable power surge, at the expense of high engine speed power.
  • Optimized Maximum Output: Unitronic development team delivers the maximum power output while staying within the operational limits of the factory components used. Specifically, this results in the highest engine performance without sacrificing the reliability of the engine, turbocharger, or other engine 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 under cruising condition for an improved fuel efficiency.
  • Speed Governor Removed: Vehicle speed limiter within ECU is removed. (If automatic, subject to transmission rotational speed limit)
  • 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.

Performance Gains: +84HP / +108TQ

  • Stage 1+

    Very good flash had a few minor issues installing on my side called Unitronic got it figured out in 10 minuets very good customer service. Overall makes my 1.8mk7 pull a lot harder very satisfied with this product.

  • Night and day!

    Low end torque is unbelievable, everyone who drove it went crazy!!! Top end is almost stock ish but that power from a dog is incredible, the car feels soooo different.

  • Can't get over how great the Unitronic folks were to work with on my 2016 A3 1.8T Stage 1+ ECU tune! The notes say that not all 2016+ models are supported and to contact the vendor to verify. I didn't have a rev. # on my car that was compatible (had 0002 and needed 0004), dealer refused to get me on rev 0004 or greater.
    John and Patryk, at Unitronic, provided the rev 004 to allow me to upgrade. They also warned that I needed a TCU to go with it.
    The ECU alone has made an enormous difference ... Was already running a new intercooler, turbo discharge, intake kit, diverter valve, perfomance exhaust, inlet pipe, throttle pipe and the tune has made the biggest differnce by far! Car is quicker off the line and fabulous on the Highway! Pushes you back in the seat regardless of the drive mode D or S! Can't wait to do Stage 2 IS20.
