Unitronic® Performance ECU/TCU Software is now available for the B9 Audi® RS 4 & RS 5® equipped with the 2.9TFSI EA839 (DECA) engine.* With testing and validations completed, power outputs are increased by up to +118HP / +149LB-FT with Unitronic Stage 1+ E85 Performance Software for a maximum of 571HP / 574LB-FT when combined with Unitronic Stage 1 AL552 TCU Performance Software for seamless operation.** These software upgrades are entirely compatible with our UniCONNECT+ cable, empowering Clients to tune their vehicles directly through the OBD-2 port within minutes, from the comfort of their own home or garage.
AVAILABLE UNITRONIC SOFTWARE
With extensive experience and a solid foundation of Performance Hardware and Software offerings for the B9 platform, Unitronic Engineers recalibrated the BOSCH MG1 ECU in the RS 4 & RS 5 with total boost regulation control, optimized ignition timing, lambda, camshaft timing and much more. Research and development continued with further dyno 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.
AL552 TCU PERFORMANCE SOFTWARE
Unitronic is proud to release its Stage 1 TCU Performance Software for the AL552 8-speed ZF gearbox, which is calibrated for use specifically with Unitronic's Stage 1 and Stage 1+ ECU Performance Software for MY2018-MY2021 vehicles. (Free for Unitronic ECU customers)
Unitronic Engineers identified gearbox originating torque limitations on the TCU side of the AL552 transmission. In order to overcome these limitations, while ensuring proper torque management and operation, TCU Performance Software is required. Stage 1 TCU Performance Software calibrations necessarily increase the torque limiter to provide seamless torque management and harmonious operation with the corresponding Unitronic ECU calibrations and further enhance the user experience. This TCU Performance Software can be flashed from home via UniCONNECT+ as well.
For MY2022+ vehicles, TCU tuning is not required as Unitronic has developed special ECU Performance Software which incorporates a proprietary "gBX" solution. These "gBX" ECU calibrations were developed specifically for MY2022+ vehicles and allow Unitronic to deliver a full torque experience without transmission tuning.
AVAILABLE UNITRONIC HARDWARE
In order to maximize performance of the 2.9TFSI EA839 engine, Unitronic developed a complete Intake System which consists of an upgraded Air Duct, Air Box and Dual Turbo Inlet, all constructed with high-quality 2/2 twill carbon fiber. Combined, this Intake System dramatically improves airflow with gains of up to 38% over the factory equipment while supporting both the stock turbochargers and TTE720 hybrid turbochargers via Unitronic's clever 48mm and 51mm adapter rings. As with all Unitronic Intake Systems, this unit provides improved throttle response, seamless integration and perfect fitment while greatly enhancing turbo induction sounds as well.
ECU SOFTWARE FEATURES
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.
This platform is supported with Unitronic’s UniCONNECT+ cable, empowering you to tune your vehicle from the comfort of your own home or garage. The cable and associated software allows you to install, and upgrade, your new Unitronic ECU/TCU tunes, flash back to stock file in addition to reading and clearing DTCs. This is a perfect option for people who like to be autonomous or who don't have a Unitronic Authorized Dealer nearby!
