    APR High Output 2.0 TSI Gen 3 ECU Upgrade

    / / APR, Automotive, Latest posts, News, Performance

    APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.0T 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 and 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, valve lift, 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 Stage I ECU Upgrade

    APR’s ECU upgrades are one of the best horsepower-per-dollar modifications for the new 2.0T engine. 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 379 ft-lbs of torque and 354 horsepower with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 98 ft-lbs of torque and 74 horsepower. Even higher figures were achieved using race fuel. For those looking for a more modest bump in horsepower and torque, lower output software is available.

    Acceleration 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.

    Increased 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.

    Speed 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 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.

    – APR recommends and tuned with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode.
    – Max increases are based on APR’s actual measured stock values and not those reported by VW. | RON = ROW Fuel Grades | AKI = North American (RON+MON)/2 Fuel Grades.
    – Reported wheel figures measured using APR’s in house Dynapack Dynamometer with a US Spec 2015 Golf R, in FWD mode, using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications.

    Acceleration Results

    Dyno testing is a great way to gauge power increases over the entire rev range but may not translate to real world performance. Through GPS based acceleration testing, APR’s Engineers were able to verify increases made on the dyno translated to a faster and quicker vehicle on the street.

    APR DirectPort Programming:

    APR’s proprietary DirectPort Programming is now available for the Simos 12.x and 18.x ECU! Any APR Dealer in the world, connected to the Internet, can gain direct access to APR’s latest ECU upgrades for loading directly over the vehicle’s OBD-II port. This eliminates the need to remove and open the ECU for currently available files and can be uninstalled and reverted to the factory unmodified stock software file at any time!

    APR ECU ExplorerAPR ECU Explorer:

    APR’s proprietary ECU Explorer gives APR’s Calibration Engineers exceptional access to the vehicle’s entire engine management system. Typical commercially available data logging tools, used by many 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. It’s capable of logging well over 100 variables at once with data rates as high as 100 samples per second.

    APR 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 many tuning companies. ECU Composer takes calibration to a new level with APR’s Quick Flashing. APR’s Calibration Engineers can reflash the ECU in seconds, rather than waiting lengthy periods of time between each flash, making testing various changes much easier.

    APR 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.
