    APR ECU Upgrade Stages

    We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Audi B9 A4 with the 2.0 TSI EA888 Gen 3B engine with the Bosch MG1 ECU! Expect massive gains with up to 242-267 HP with 330-363 FT-LBS of torque on tap, depending on octane and mods! Additionally APR Plus is available in the USA which adds a factory term limit matching limited powertrain warranty and is offered on our 91 AKI ECU upgrade!


    Our new suite of MG1 ECU software comes after months of extensive research and development that is typically absent from the aftermarket. Our upgrade makes the engine more powerful and more exciting. We’ve extensively calibrated the system to work flawlessly in various driving conditions while retaining safety routines to protect your engine in the most demanding scenarios. This was all made possible by our engineering team's pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After many hours of testing and tuning we created new calibrations that are fine tuned for several octanes and contain hundreds of map changes, with a vast array of safety features built in.


    The result of this work is nothing short of astounding. Not only have we increase power, we’ve added many safety routines to ensure the engine and components are protected under demanding scenarios. Additionally we’ve added features to enhance the driving experience! We’ve added brake boosting / left foot braking, removed the vehicle speed limiter, raised the standing limiter, set auto start/stop to default off, and enabled burnout mode which is activated during a lunch by hitting the throttle kick down switch.


    To protect the engine and components we’ve spent a considerable amount of time tuning safety routines, some of which were not active from the factory. The engine has advanced LSPI protection to prevent the engine from damage when being lugged in the tallest gears. Excessive intake air temperature, which is common on a dynamometer, will cause power to reduce to protect the engine. Furthermore more we’ve added and calibrated protection routines for turbocharger pressure ratios, shaft speed, exhaust pressure, intake air temperature, turbo discharge temperature, coolant temperature, oil temperature, lambda, fueling system limitations, and more.

    Performance Stages

    OEM Turbo Software

    The APR Stage 1 ECU upgrades are designed for use on the factory turbocharger. The ECU alone with no hardware mods produces 242-267 HP with 330-363 FT-LBS with +54-77 WHP and +93-127 WFT-LBS over stock.


    This tune is available for 91, 93, 100, and 104 AKI fuel grades, as well as E60-E85 Ethanol in North America and 95, 98, 104, and 108 RON fuel grades, and E60-E85 Ethanol in the ROW.


    APR Plus is optionally available and adds our limited powertrain warranty to this stage. It's available for 91 AKI fuel grades in the USA and requires the use of original factory or APR approved hardware only.


    When selecting a fuel grade, a minimum of that fuel grade must be used. Using higher fuel grades is permissible.
