1.8 TFSI - APR ECU Upgrade

engineAPR is pleased to present the ultimate engine control unit (ECU) upgrade for the 1.8T EA888 Gen 1 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 ECU’s MED 17 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.

Stage I ECU Upgrade

Not only does our Stage I ECU Upgrade give you higher peak numbers of 189 horsepower and 226lb-ft. of torque, but also gains of up to 44 horsepower and 60lb-ft are available throughout the power band!

APR Mobile

APR Mobile is a simple yet powerful tool designed to enhance the APR tuning experience.

APR Mobile

APR Mobile installs on smart phones, tablets and other devices and provides a wireless connection to the vehicle’s engine control unit or ECU. Once connected, the device can be used to access APR’s EMCS program switching features, read and clear fault codes and data log the ECU at high data rates not found on other commercially available tools. The app can also be used to access APR’s latest news articles, locate dealers in APR’s network and review previously saved data logging sessions.

How EMCS Works

Step 1

Press and hold the "set" button on your cruise control. After approximately five seconds, the "check engine" light on your dash will begin to blink once per second. This will tell you that you are activating program one. This blinking sequence will continue for approximately five seconds.

After this five second interval, the "check engine" light will begin blinking twice per second. This will indicate that you have activated the second program. This process is continued to access any remaining programs you may have purchased. (three blinks = program three, four blinks = program four).

Step 2

Once you have activated the desired program, simply release the "set" button. The "check engine" light will stop flashing. Turn the ignition key off for 10 seconds, turn the key back on, and you will be locked in that program until you change it again.

It's that simple.

Available Features

APR's EMCS is a truly modular system that allows for future enhancements and features to be added as they are developed without the need for additional hardware. EMCS makes the following advanced features possible:

  • Program Switching Enables you to swap between two or more engine programs using the cruise control stalk. All cars have stock and standard chipped program versions available. Valet, race-gas, and other specialty programs are available for most models.
  • Fault Code Erase/Throttle Body Alignment (FCE/TBA) Fault Code Erase allows you to erase and reset engine related trouble codes without having to use a specialty tool. Throttle Body Alignment allows you to manually perform throttle-body adaptation.
  • Security Lockout Prevents unauthorized personnel from accessing EMCS functions. The user may select any 2 to 4 digit security code. The security code is entered using the cruise control buttons.
  • Anti-Theft You can render your car immobile to thieves, even if there is an attempt to start the car with your own key! For more information about Anti-Theft, click here.
