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.
