"There is only one APR."

For over 10 years, no one has been able to simulate what APR's EMCS does. 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 "chipping" 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 chip available for the 997 Carrera S. 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 997 Carrera S upgraded chip comes EMCS equipped (Enhanced Modular Chipping System). The "extra steps" don't stop with the software development process. Our chipping hardware 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 chip 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.

All APR Porsche ECU applications come loaded with the following EMCS options. For more information on EMCS and how it works, check out the EMCS page.

• Stock Program
  
• Chipped Program (91 or 93 octane)*
  
• Valet Program
  
• Race Program (100 or 104 octane)*
  
• Security Lock Out Feature
  
• Fault Code Erase and Throttle Body Alignment
  
• Anti-Theft System

*when running a particular octane specific program, fuel containing that octane or higher must be used. Example: If running the 93 octane program, do not use less than 93 octane fuel. However, higher octane fuel, such as 94 octane, is fine.

All of these features come standard with the APR ECU upgrade and each mode can be selected at the touch of a button.

 APR ECU Modification Order Form(119K pdf)

A third option is to order a spare ECU and have us install the modified chip before sending it on to you. This will allow one to swap the stock engine computer back in when getting the car serviced. The spare ECU's that we sell are new factory units. Because of this, there are no refunds on spare ECU's, only on the APR software. For more information on this, see the Terms and Conditions of Sale.
