Please note, all DirectPort upgrades must be done IN-HOUSE at one of NGP's two locations. Email for all inquires on sending in your ECU for upgrading at NGP.

APR is pleased to present the ultimate ECU Upgrade for the Porsche 997 911 3.6L engine. After months of long nights and many hours of testing, development and more testing, we are pleased to offer you an ECU recalibration that is second to none. APR's extensive research and development provides you with a powerful ECU Upgrade with no loss of drivability or reliability. Expect increases in low-end torque, improved throttle response and a smoother, more powerful top end.

 "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 ECU Upgrade available for the 997 Carrera. We go far beyond the traditional steps of just "leaning out the air fuel ratio" 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. 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.

The APR 997 3.6L ECU Upgrade comes EMCS equipped (Enhanced Modular Chipping System). The "Extra steps" don't stop with the software development process. Our ECU Upgrade 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 ECU Upgrade 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.
