Low torque files are necessary on manual transmission vehicles using the factory clutch. Low torque files are also necessary on DSG/S-Tronic vehicles unless running our TCU upgrade. Only use fuel equal to or higher than specified. Never use a lower octane fuel. Always follow our fuel guide, especially with race fuel and Ethanol, where available. Dynos are for reference only. Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number.

  • Question

    Hello, What is the 0-60 time on the stage 2 E60-E85 Ethanol Mk8 Golf R?

    By Joseph Shafiei on April 9, 2023

    Answer
    We went from 4.0 to 3.32 on Stage 1 93. No other mods. Stock wheels and tires. I don't have Stage 2 or E85 times.

  • Question

    I have a 2022 VW Arteon R Line, that shares the same engine with the Golf R (EA888Gen4). Would this fit my car or is this specific just for the GolfR?

    By Thomas Miles on June 21, 2023

    Answer
    It eventually will, but the ECU is on a slightly different operating system we haven't released yet. Stay tuned for a release!

APR ECU Upgrade Stages

We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Volkswagen Golf R (MK8), Arteon, and Audi S3 (8Y) 2.0 TSI EA888 Gen 4 engine with the Continental Simos 19 ECU! Expect massive gains with up to 398-455 HP with 385-436 FT-LBS of torque on tap, depending on octane and mods! This represents up to 43-51% more horsepower at the wheels, over stock! Additionally APR Plus is available which adds a factory term limit matching limited powertrain warranty and is offered on our 91 AKI ECU upgrades!


Our new suite of Simos 19 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 retain your last used mode, properly rescaled the boost and power gauges, developed a linear and flat torque curve, and linearized the throttle pedal.


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. On 6MT equipped vehicles, you’ll achieve full torque, but on DSG equipped vehicles, torque will be limited at the factory limits until our TCU upgrade is added. Furthermore more we’ve added and calibrated protection routines for turbocharger pressure ratios, shaft speed, exhaust pressure, intake air temperature, coolant temperature, oil temperature, lambda, fueling system limitations, and more.


Our ECU Upgrades are available in multiple configurations. Installation of additional performance hardware, such as an intercooler or intake systems, may provide further performance improvements.

Performance Stages

OEM TURBO SOFTWARE (STAGE 1 AND STAGE 2)

The APR Stage 1 and Stage 2 ECU upgrades are designed for use on the factory turbocharger. The ECU alone with no hardware mods produces 398-442 HP and 385-430 FT-LBS with +64-112 WHP and +76-118 WFT-LBS over stock. By adding hardware such as our intake and intercooler, the tune automatically jumps to Stage 2 power levels and produces 410-455 HP and 389-436 FT-LBS with +74-123 WHP and +80-125 WFT-LBS over stock.


Optional Low Torque Files

For manual transmission vehicles, this file helps alleviate stress on the factory clutch. Upgrade the clutch to run the high torque file.

On DSG/S-Tronic transmission vehicles, running this file is necessary to prevent slip. Run our TCU upgrade to remove torque caps and to prevent slip.


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


APR Plus is optionally available and adds our limited powertrain warranty to this stage. It's available for 91 AKI fuel grade 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.
