Audi RS6 - APR ECU Upgrade
"There is only one APR."
For over 10 years, no one has been able to simulate what APR's ECU Upgrade accomplishes. Our staff of 10 engineers and 30+ employees has broken the mold of "performance tuning" by developing new technology that allows for the development of the highest quality performance available. APR has revolutionized "chip tuning" with unparalleled innovation. There is only one performance engineering firm that offers software so refined and complete with so many options. There is only one APR.
"Extra steps must be taken."
From the development process to the technical features, no other tuner offers the same innovation and refinement that you'll get from APR. Many months have been spent developing the best ECU Upgrade available for the RS6. We go far beyond the traditional steps of just "raising the boost" and "advancing the timing". Extra steps must be taken. Typical data logging software used by most tuners is capable of capturing 4 variables at 3 samples per second. APR's proprietary data acquisition software captures as many as 30 variables at around 22Hz. That's an incredible 55 times more data gathered per second.
"...extra steps other tuners can't take."
To dramatically increase power and maintain factory drivability there are many factors to be considered. One of note is the internal boost-controller, which requests boost according to load measured by the ECU. Inconsistencies and "surging" are things you will not feel in APR software because we properly match the cars actual boost produced with the load-based requested boost from the ECU. This is where "55 times more data" goes from intangible numbers to a smoothness you can feel. It helps duplicate the characteristics normally found only from the factory. Such precise matching you will not find in other software. These are extra steps other tuners can't take.
"...any tuner in any market anywhere in the world."
The APR RS6 ECU Upgrade comes EMCS equipped (Enhanced Modular Chipping System). The "extra steps" don't stop with the software development process. Our ECU Upgrade development far surpasses anything else offered by any tuner in any market anywhere in the world. We have left the traditional method of re-flashing a chip in the 90's and have moved on to the next generation of ECU Upgrade tuning. No longer are you limited to replacing one program with another program. With our EMCS, you can replace one program with four programs and several ECU features. The APR RS6 ECU Upgrade also includes new programming for the transmission computer in the car, raising the shift points by 200rpm.

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 104 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, 95, 98 and 104 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
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.
Installation Options
APR's ECU Upgrade is able to be installed by APR's professional dealer network or by APR directly. Most late model applications are available to be installed via DirectPort programming without removing your ECU or even opening the hood. DirectPort Programming is not available for all 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.
EMCS Module
EMCS Modules are still available for most ECU Upgrade installations. EMCS Modules are required for some older model ECU Upgrade installations where DirectPort Programming is not available. Clients may choose to have an EMCS Module installed over DPP if there is not an APR dealer close by or if the ECU's OEM memory module is too small to accept all EMCS options via DPP.
How to Purchase
APR provides two easy and painless methods to purchase your ECU Upgrade. You may visit any APR Dealer for local installation while you wait or you can remove your ECU and send it directly to APR Headquarters for installation. Typically your ECU is returned the same day we receive it. For ECU removal instructions see our Customer Support page.
If you're sending your ECU in to us, please print out and complete the order form below. Be sure to indicate which programs you would like to purchase, as well as the other information requested. For information on the program options, see above under the EMCS heading.
