APR Tuning

APR tuning for Audi automobiles is derived from extensive development and testing by APR LLC, an Audi tuning and automotive engineering firm founded in 1997 and operating out of Alabama in the USA. APR specializes in developing aftermarket performance products for Audi and other VAG vehicles.



APR Tuning Features

The APR ECU upgrade program remaps boost pressure (where applicable), timing and air-fuel ratios to provide smooth and reliable power. APR's ECU upgrade is developed to work within the OEM and Tier 1 supplier tolerance specifications for engine component stress, and APR tuning is available in octane-specific versions to allow full adaptation to your local fuel quality.

APR's ECU upgrade promises no loss of drivability or reliability, large increases in low-end torque, improved throttle response and a smoother, more powerful top end. It also does not require additional hardware or a transmission software upgrade to achieve its advertised power claims.

APR's Audi tuning is encrypted to protect your ECU map and to make it invisible to your local Audi dealer, and APR offers a 6-hour free trial on its Stage 1 software for potential customers.


APR Enhanced Modular Chipping System (EMCS)

APR's patented Enhanced Modular Chipping System brings many new features to the Audi enthusiast. EMCS offers several modes for your Audi: Stock (factory settings), Performance (91 and/or 93 octane), Race (100 octane fuel for track use), and Valet to limit power.

These modes are fully integrated into your Audi's OEM cruise control buttons for stealth and ease of use. Cruise control functions will continue to operate as usual, but with the additional ability to scroll through the APR programs installed. At the touch of a button, APR's EMCS system is able to completely rewrite the entire tuning map and replace it with the program of your choice. New APR programs can also be added on to the modular system without the need for additional hardware.

Additionally, APR's EMCS provides several unique features. Fault Code Erase allows you to erase and reset engine-related trouble codes without having to use a specialty tool like the VAG-COM. Throttle Body Alignment allows you to manually perform throttle-body adaptation. The Security Lockout feature prevents unauthorized personnel from accessing EMCS functions with a 2- to 4-digit security code entered via the cruise control buttons. And an Anti-Theft mode is available to render your car immobile to thieves, even if there is an attempt to start the car with your own key.
