APR 1.8 TSI/TFSI Longitudinal ECU Upgrade
APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 1.8 TFSI 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. APR’s EMCS functionality puts the control of the engine’s operation at your fingertips and allows for additional features and options to be installed to the OEM ECU.
The Bosch MED17 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 turbocharger boost pressure and optimizes cam timing, ignition timing, lambda and more to produce higher output. Using APR’s proprietary high-speed data logging suite, the calibration team closely monitored the effects of these changes to help ensure an enjoyable driving experience.
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!
Stage I ECU Upgrade
Not only does our Stage I ECU Upgrade give you higher peak numbers of 210 horsepower and 285lb-ft. of torque, but also gains of up to 69 horsepower and 103lb-ft on the 160 HP engine and 91 HP and 115lb-ft on the 120 HP engine are available throughout the power band!

APR EMCS Programs and Features
APR’s EMCS, Enhanced Modular Chipping System, brings selectable programs and features to your factory ECU, all without the need to purchase external hardware. Others have attempted to imitate EMCS with external switching devices that only replace or multiply portions of a “base” calibration. However, EMCS has the ability to completely rewrite the entire operating map data, giving each map a complete set of calibration changes. APR’s EMCS features and programs modes are activated via your OEM cruise control buttons. Your cruise control will continue to function as normal.
To learn how to activate the programs and features, choose the vehicle's cruise control type from APR EMCS Owner's Manual.
Program Switching:
Program switching allows the user to cycle through up to four different engine calibrations and operating modes all without the need for external hardware.
Stock Mode:
By selecting stock mode, the ECU calibration is reset to the factory calibration. The engine will run as it did before purchasing APR software.
APR Performance Modes:
APR's octane-specific calibrations are available for various premium and race fuels around the world. Each performance mode is a completely new calibration, altered specifically for the characteristics of the fuel quality selected.
Fault Code Erase:
Fault code erase allows the user to erase and reset engine related trouble codes and ECU adaptation data without using a specialty tool.
Security Lockout:
Security lockout prevents unauthorized individuals from using APR's EMCS functionality. When enabled, APR's EMCS features will appear completely invisible until a user specified 2 to 4-digit security code is entered.
Anti-Theft:
When activated, Anti-Theft prevents the engine from starting even if the factory key is used. The vehicle will be completely immobilized until a user specified 2 to 4-digit security code is entered.
Valet Mode:
APR's Valet Mode protects your vehicle from becoming an expensive toy for unauthorized individuals. By enabling Valet Mode, the vehicle's performance is extremely limited.

The APR Development Difference
APR 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 without a trace!
APR 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 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 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.
