APR 2.0 TSI Gen3 ECU Upgrade

engineAPR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.0 TSI EA888 Gen 3 engine. APR’s ECU upgrade is available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU.

The ECU’s Simos 12 / 18 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.

APR's Calibration Engineers spent months calibrating the engine management system, including many hours of chassis dyno development. With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque across the entire power band. APR’s ECU Upgrade increases boost pressure, optimizes ignition timing, cam timing, lambda and more to produce higher output!

APR’s ECU Upgrades provides an excellent leap in horsepower and torque while retaining OEM knock control sensitivity and other built in safety features. This results in an exciting and powerful upgrade, optimized for various fuel grades found around the world

APR ECU Upgrades


The APR Stage I ECU Upgrade is designed to work without requiring other changes to the vehicle’s hardware. With the ECU Upgrade alone, APR’s Calibration Experts measured higher peak figures of 302 ft-lbs of torque and 261 horsepower with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 67 ft-lbs of torque and 52 horsepower. Even higher figures were acheived using 100 AKI octane race fuel. The increase in power directly translates to an exceptionally quicker vehicle. Using advanced GPS measuring devices, APR’s engineers conducted several acceleration tests. During the 60-130 MPH sprint, the APR Stage I equipped vehicle crossed the finish line 4.829 seconds quicker, resulting in an excellent 20.66% improvement!

The APR Stage II ECU Upgrade is designed to work with APR’s Exhaust Downpipe. When combined with APR’s Intake System, peak power and torque figures grew further to 280 horsepower and 321 ft-lbs of torque. The additional hardware allowed the turbo to spool faster and power carried better towards redline, resulting in up to an additional 40 ft-lbs of torque and 25 horsepower.

rabbitAcceleration Enhancements:
Beyond horsepower and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle through other calibrations changes. Ignition delay is reduced resulting in a more responsive pedal without altering overall throttle sensitivity. Furthermore, throttle lag commonly noticed at slow speeds and while reapplying throttle has been reduced.

ecoIncreased Fuel Economy:
APR’s Calibration Engineers paid close attention to several parameters directly related to fuel economy, especially while cruising at highway speeds. Depending on driving style and fuel quality, better miles per gallon may be achieved.

vmaxSpeed Limiter:
APR’s ECU upgrade increases the vehicle's top speed limiter for blistering sprints around the track or across the Autobahn without the speed limiter shutting down the fun.

Left Foot BrakingLeft Foot Braking:
APR's Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped vehicle's throttle input is disabled while pressing the accelerator and brake at the same time. Left Foot Braking, a common motorsport driving technique, allows the driver complete control over the vehicle’s throttle and braking system, which may give the vehicle the edge it needs at the track.

The APR Development Difference

DirectPort ProgrammingAPR DirectPort Programming:
APR’s DirectPort Programming is now available! Any APR Dealer in the world, connected to the Internet, has direct access to APR’s latest ECU upgrades for loading directly over the vehicle's OBD-II port. This completely eliminates the need to remove and open the ECU for currently available files and can be uninstalled at any time!

APR ECU ExplorerAPR ECU Explorer:
APR’s proprietary ECU Explorer gives APR’s Calibration Engineers unparalleled access to the vehicle’s entire engine management system. Typical commercially available data logging tools, used by most tuners, only allow logging up to 12 engine-operating variables at extremely low data rates. These tools are also limited to a small, specific list of variables. APR’s ECU Explorer is capable of logging every variable found within the ECU with far more variables logged at once, at very high data rates.

APR ECU ComposerAPR ECU Composer:
APR’s proprietary ECU Composer is used for altering the engine management system. With full access to every table, map and variable within the ECU, APR’s Calibration Engineers are not limited to a handful of maps as is common for most tuning companies.

APR ECU AssemblyAPR ECU Assembly:
APR’s Electrical Engineers have the ability to alter the code structure of the ECU. Through code levels changes, APR's Engineers are able to add features to the ECU. Other changes allow higher torque limits than those achievable through only modifying calibration data or using piggyback devices as is the case for many tuners. This allows APR's engineers to often not require transmission software to meet or exceed advertised gains. On the highly modified end, this often allows APR to make turbo upgrades operate without the need for external manual controllers.
