Description

Overview

APR's ECU Upgrades are the best dollar-per-horsepower modification one can make to improve engine performance. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR's optimization of the factory engine management system to take full advantage of the engine's capabilities, without needing any end user adjustment. The ECU Upgrades are available with various features and supported octane levels and each stage is compatible with most typical bolt-on modifications. The software is installed to the vehicle's factory ECU through the OBD-II port, resulting in a clean and headache-free install. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!

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.

APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.0T EA888 Gen 3 engine!

APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 2.0T engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install.

APR ECU Upgrade Stages

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.

APR Stage 1

The APR Stage 1 ECU Upgrade is the first step towards tuning your engine. It produces up to 357-381 HP and 349-392 FT-LBS of torque. Optional low torque files are available for use with the Stock TCU on the 6 speed DSG/S Tronic, or stock clutch. Optional torque limited files are available to limit wheel spin on FWD applications. APR Spark Plugs are recommended.

APR Stage 1 is available for 91 AKI, 93 AKI, and 100 AKI in North America, and 95 RON, 98 RON, 102 RON, and 104 AKI in the Rest of the World.

To get more power, the vehicle can be outfitted with an upgraded intake, intercooler, catback exhaust and other small modifications without requiring any new modification to the ECU. For those looking for even more power, check out our Stage 1 ECU upgrade. APR recommends using colder heat-range spark plugs (Ex: NGK-R7437-9), properly gapped to a tighter gap (Ex: 0.024" ±0.002" or 0.6mm ±0.05mm), properly installed and torqued

APR Stage 2

The APR Stage 2 ECU Upgrade is the next step towards tuning your engine. It produces up to 372-387 HP and 367-409 FT-LBS of torque. Optional low and medium low torque files are available for use with the Stock TCU on the 6 speed DSG/S Tronic, or stock clutch. Optional torque limited files are available to limit wheel spin on FWD applications. Additionally this stage is available with optional crackle modes. The more aggressive modes increase the length, duration, intensity, and operating modes of the crackle. APR Spark Plugs are recommended.

APR Stage 2 is available for 91 AKI, and 93 AKI in North America, and 95 RON, and 98 RON in the Rest of the World.

APR Stage 3 DTR6054

The APR Stage 3 ECU Upgrade is the next step towards tuning your engine. It produces up to 410-491 HP and 370-425 FT-LBS of torque. Use this tune with the APR DTR6054 turbocharger.

APR Stage 3 Plus EFR7163

The APR Stage 3+ ECU Upgrade is the next step towards tuning your engine. It produces up to 470-536 HP and 425-474 FT-LBS of torque. Use this tune with the APR EFR7163 turbocharger and APR MPI/LPFP (NAR) or LPFP/HPFP (ROW) fueling upgrade.

APR Stage 3+ is available for 91 AKI, 93 AKI, 100 AKI, and 104 AKI in North America, and 95 RON, 98 RON, 104 AKI, and 108 AKI in the Rest of the World.

Enhance your exhaust note just like Audi’s latest RS models! The APR Exhaust Crackle, lovingly called “pops and bangs” by many, adds a distinct crackle to the exhaust note upon lifting off the throttle, gear changes on a manual, decelerating, or while free revving at a stand standstill. This optional feature is available at no cost, at the time of flashing, for most compatible ECUs at stage 2 and higher stages. For convenience, the feature is only enabled when the vehicle is placed into sport/race mode. Lastly, for safety, this feature has built in hardware protection limits, and will only function when it’s considered safe to do so. We offer this in both a "soft" and "aggressive" mode as illustrated below with our 2019 Golf R featuring a full APR Valved Catback Exhaust System.

Who we are - We’re a global automotive engineering firm nestled in Opelika, Alabama. Our 80,000ft² state-of-the-art facility is home to some of the best engineers in the industry, who have mastered hundreds of engine management systems. We have multiple engine and chassis dynos, and the resources necessary to create our ECU Upgrades in-house, from the ground up! We're not a new company either. We've been around since the 90's and we have a strong financial backing to ensure we'll be here to support you for decades to come!

What we do - We optimize everything to make your engine more powerful. We adjust air-fuel ratios, advance ignition, increase boost pressure, alter cam positions and lift profiles, and more, all depending on the type of engine and management system, of course! We don’t take shortcuts, and we don’t take risks. We do it the right way.

How we differ - With our proprietary calibration and direct ram access data logging tools and operating system code changes, we’re able to make some of the strongest and fastest ECU upgrades, without needing costly end user adjustments. We work with the ECUs intelligent modeling and closed-loop systems, and beta test in multiple environments to create upgrades that work no matter where you drive!
