 Product Description

The APR 1.8T 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.


APR EMCS Programs & Features:

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.

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.

Program Switching:  Program switching allows the user to cycle through up to four different engine calibrations and operating modes all without
the need for external hardware.

Stock Mode:  By selecting stock mode, the ECU calibration is reset to the factory calibration. The engine will run exactly as it did before
purchasing APR software.

APR Performance Modes:  APR's octane-specific calibrations are available for various premium and race fuels around the world. Each
performance mode is a completely new calibration, altered specifically for the characteristics of the fuel quality selected.

Valet Mode:  APR's Valet Mode protects your vehicle from becoming an expensive toy for unauthorized individuals. By enabling Valet Mode, the
vehicle's performance is extremely limited. Launch control is uneventful, the vehicles top speed is limited to roughly 40 MPH and the engine's
redline is reduced to nearly 5,000 RPM!

Fault Code Erase: Fault code erase allows the user to erase and reset engine related trouble codes and ECU adaptation data without using a
specialty tool.

Security Lockout:  Security lockout prevents unauthorized individuals from using APR's EMCS functionality. When enabled, APR's EMCS features
will appear completely invisible until a user specified 2 to 4-digit security code is entered.

Anti-Theft:  When activated, Anti-Theft prevents the engine from starting even if the factory key is used. The vehicle will be completely immobilized
until a user specified 2 to 4-digit security code is entered.
