Unitronic® Performance Software is NOW AVAILABLE for the 2.0TSI MLB (CYMC/CYRB) engine found in the 2017+ (B9) Audi® A4®, Audi® A4® Allroad®, A5® Coupe and A5® Sportback. Unitronic’s Performance Software is compatible with UniCONNECT+™, empowering Clients to tune it themselves directly through the OBD-2 port within minutes, from the comfort of their own home or garage.
With baseline figures and data acquisition completed in stock format, Unitronic interprets the data and recalibrates the engine control unit to achieve optimal performance through an increase in boost, optimized ignition timing, lambda, camshaft timing, and much more. Research and development of Unitronic’s Performance Software continues with further dyno, track, and road testing, while closely monitoring running conditions through high-speed data logging tools and equipment to ensure maximum performance is achieved, while maintaining complete OEM-like reliability and drivability.
After hundreds of hours of development time is spent, a multitude of empirical data collected and analyzed, and real-world testing in the field throughout the world is completed, Unitronic Performance Software is fully optimized for maximum performance while staying within the constraints of the OEM hardware to ensure reliability and drivability is maintained, resulting in Stage 1 (91 octane/95 RON)and Stage 1+ (93oct/98 RON) ECU calibrations.
Unitronic’s Stage 1 Performance Software is calibrated for 91 octane fuel (95 RON) and intended for an otherwise completely stock vehicle, producing 303 HP / 336 LB-FT of torque.
Unitronic’s Stage 1+ Performance Software is calibrated for 93 octane fuel (98 RON), also intended for an otherwise completely stock vehicle, producing 311 HP / 346 LB-FT of torque. Stage 1+ also does not require any other supporting hardware modifications!
Unitronic’s Performance Software for the 2018+ B9 A4/A5 is programmable directly through the OBD-II port and is UniCONNECT+compatible. Within minutes, Clients can enjoy a total night-and-day driving experience! UniCONNECT + is Unitronic's End-User Programming and Diagnostic Interface, which provides its Clients the freedom to flash their Engine Control Unit (ECU) from the comfort of their home or garage. It is no longer necessary to schedule an appointment at an Authorized Unitronic Dealer to have your Performance Software installed, removed, upgraded or reflashed. UniCONNECT + empowers its Unitronic Performance Software Clients with the freedom to tune their vehicle at their will.

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.
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.
