APR ECU Upgrade Stages

We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Volkswagen GTI (MK8), Audi A3, Cupra Formentor and Leon, and Skoda Octavia with the 2.0 TSI EA888 Gen 4 engine with the Continental Simos 19 ECU! Expect massive gains with up to 328-478 HP with 391-443 FT-LBS of torque on tap, depending on octane and mods! This represents up to 111% more horsepower at the wheels, over stock! Additionally APR Plus is available in the USA which adds a factory term limit matching limited powertrain warranty and is offered on our 87 AKI or 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. 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.


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 328-375 HP and 391-427 FT-LBS with +63-105 WHP and +96-129 WFT-LBS over stock. By adding hardware such as our intake and intercooler, the tune automatically jumps to Stage 2 power levels and produces 345-392 HP and 391-428 FT-LBS with +76-122 WHP and +96-131 WFT-LBS over stock.


For manual transmission vehicles torque can be optionally limited to help alleviate stress on the factory clutch. On DSG/S-Tronic equipped vehicles, torque is also limited, but the limit is removed with our Transmission Control Unit (TCU) upgrade.


This tune is available for 87, 91, 93, 100, and 104 AKI fuel grades, as well as E60-E85 Ethanol in North America and 91, 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 87 or 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.

Upgraded Turbocharger Software (Stage 3)

The APR Stage 3 OEM ECU upgrade is designed for use with the larger OEM Continental turbocharger found on vehicles such as the MK8 Golf R and S3 (8Y)! This tune produces up to 410-478 HP and 400-443 FT-LBS with +142-211 WHP and +119-179 WFT-LBS over stock.


Transmission:

For manual transmission vehicles, torque can be limited to help alleviate stress on the factory clutch, but upgrading is highly recommended. On DSG/S-Tronic equipped vehicles, torque is also limited, but the limit is removed with our Transmission Control Unit (TCU) upgrade.


Fuel grades:

This tune is available for 91, 93, 100, and 104 AKI fuel grades, as well as E60-E85 Ethanol in North America. When selecting a fuel grade, a minimum of that fuel grade must be used. Using higher fuel grades is permissible.


Hardware requirements and recommendations:


  • OEM Golf R/S3 Continental Turbocharger System
  • APR Intake System (to achieve and sustain advertised power levels)
  • APR Intercooler System (to achieve and sustain advertised power levels)
  • APR TCU Upgrade or 6MT clutch upgrade (to run higher torque levels)


No modification is necessary to any exhaust components, fueling system, or sensors!


This upgraded turbo makes several changes to the GTI’s factory intake system, diverter valve, and charge pipes routing. Depending on your current setup, different parts will be necessary.


Turbocharger:

Factory Golf R/S3 Continental Turbocharger (06Q145703G)


Fit Kit:

Factory Oil line (06Q145778D), gaskets, o-rings, and other one-time use bolts will need to be replaced.


Intake Pipes/Hoses:

The intake system requires a different turbo inlet that fits the larger Continental turbo. It also requires a DV recirculation bung. If your intake is stock, run the APR (CI100053) Intake System designed for the Golf R/S3. If you are running the APR (CI100052) Intake System, swap to the APR (CI100053-B) Intake Back Pipe and use the APR (CI100052-C) Turbo Inlet Adapter.


Charge Pipes/Hoses:

The continental turbo moves the factory DV off of the turbo and onto the throttle body inlet pipe, and uses a different DV. The turbo also removes the turbo muffler from the turbocharger. Use the APR (MS100222) Throttle Body Pipe with a factory DV (06N145710B) and DV recirculation hose (5WA145693C). The DV harness will need to be extended, or removed from the loom and relocated. If you have the APR (MS100227) turbo muffler eliminator, remove the eliminator and reuse the Turbo Outlet Hose. If you have the factory hoses, use the APR (MS100225) Turbo Outlet Hose.


Stay tuned for future APR conversion kits to make this process easier!
