– APR ECU Upgrade

APR is pleased to present the ultimate ECU Upgrade for the 2.7T engine. After months of long nights and many hours of testing, development and more testing, we are pleased to offer you an ECU recalibration that is second to none. APR’s extensive research and development provides you with a powerful ECU Upgrade with no loss of drivability or reliability.

Expect huge increases in low-end torque, improved throttle response and a smoother, more powerful top end.

The APR 2.7T ECU Upgrade is an expertly recalibrated engine control strategy that remaps the boost pressure, timing and air fuel ratios to provide smooth and reliable power as if intended by the OEM. APR’s ECU Upgrade is developed to work within the OEM and Tier 1 Supplier specifications for engine component stress tolerances and performance specifications. APR’s ECU Upgrades are available in octane specific versions to allow you to take full advantage of the fuel quality available in your area.

APR’s patented EMCS functionality puts the control of the engine’s operation at your finger tips and allows for additional features and options to be installed to your OEM ECU.

Stage I Performance

EMCS

EMCS is APR’s revolutionary patented Enhanced Modular Chipping System. EMCS is an industry leading technology that brings many new features to the automotive enthusiast. This technology was developed exclusively by Audi Performance Racing, LLC and demonstrates APR’s continued commitment to lead the industry with the most technologically advanced products available.

Want chipped mode? Want to be able to switch back to your stock settings? Want a race mode to run 100 octane fuel at the track? How about a valet mode that limits power?

EMCS is the lone technology on the market that can give you all of these options. No changing of the chip or ECU is required. These programs are available at the touch of a button.

Other companies have attempted to imitate EMCS with clumsy external switching devices that only replace portions of a base calibration. EMCS is still the only Bosch Motronic Engine Management System enhancement that gives the ECU the ability to completely rewrite the entire operating map data when selecting different programming options. This allows for completely new and independent calibrations for each program selected giving you the best, most powerful and complete Stock Modes, 91, 93 and 100 octane Performance Modes and Valet Modes.

APR’s EMCS features and program modes are activated via your OEM cruise control buttons for ease of use and stealth. Your cruise control will continue to function as normal, but will give you the ability to scroll through the programs you have purchased with your APR ECU Upgrade. The procedure is simple and involves only two steps.

How EMCS Works

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.

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 .

Installation Options

APR’s ECU Upgrade is able to be installed by APR’s professional dealer network or by APR directly. Some applications are available to be installed via DirectPort programming without removing your ECU or even opening the hood. Some ECUs must be removed from the vehicle for DirectPort Programming.

DirectPort Programming is not available for all late 1990 / early 2000 models and in these rare cases EMCS Modules are able to be soldered to the ECU. In the event there is not an APR dealer near, you also have the option to remove your ECU and send it to APR Headquarters for installation.
