APR's EMCS software is available for the 150 horsepower (112Kw) A3 and the later VVT (Variable Valve Timing) cars. The software for the A3 is available in a 1.0 bar configuration and 196 horsepower (146Kw) and 240 ft. lbs (325Nm) of torque. On the later VVT motor, which also as a different turbocharger specification, the horsepower gains are increased to around 207 horsepower (154Kw) but with same torque. Our software is designed to operate within the turbochargers' efficiency range whilst producing huge increase in low end torque, improved throttle response and a much smoother, more powerful top end. Unlike other "chip tuning companies", we do not max out the boost pressure sensor in order to boost spike and give high initial torque readings. Although this maybe good for marketing purposes, it not only creates surge during acceleration at low RPM, but also reduces the life expectancy of the turbocharger considerably.

The EMCS is operated via a pushbutton that can be installed anywhere in the car and uses the engine check light on the instrument cluster to identify program changes.

All APR chip upgrades use encryption, which serve several purposes. First, it keeps prying eyes out of our software and prevents lesser companies from copying the chip and degrading the product. Secondly, the encryption prevents the dealer from flash programming the ECU. Also, all APR software is undetectable to a dealers VAG diagnostic tool.

All APR chip software comes with lifetime free upgrades. There is also a lifetime warranty against defects in the software or soldering. All chip upgrades have a 30-day Money Back Guarantee.

EMCS

(Only available for cars with drive by wire)
EMCS is available for this car. 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. EMCS 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.

EMCS consists of three important parts that work together as a cohesive unit: the EMCS module (which is soldered to the engine computer board), the EMCS on-board software (the software that is on the module), and the support software that is used to program and reprogram the module.

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:

FlipSwitch
Enables you to swap between two or more engine programs on-the-fly using a pushbutton. All cars have stock and standard chipped program versions available. Valet, race-gas, and other specialty programs are available for some 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.

User Reprogramming and Reconfiguration
Gives the user the ability to reprogram their ECU with the latest software updates and to reconfigure their ECU for different preferences or to function with different hardware. This function requires the optional programming adaptor.

EMCS PRICING

All APR chips now include EMCS hardware. EMCS options are available at an additional cost over the normal price of a chip. Please remember that even if you do not purchase any of the following options, you will still be able upgrade to these options from most any internet accessible computer at a later date.

Above the price of the chip for your car, the following options can be added to your ECU:
