Achtuning is pleased to announce APR’s release of the ultimate ECU Upgrade for the 3.0 TDI!!
After months of long nights and many hours of testing, developing and more testing, APR is 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 faster acceleration, improved accelerator response and more torque across the entire power band.
APR’s 3.0 TDI ECU Upgrade is an expertly recalibrated engine management control strategy that increases horsepower and torque to provide smooth and reliable operation 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 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 Stage I ECU Upgrade
The APR Stage I ECU Upgrade gives you higher peak numbers of 261 HP and 452 FT-LBS of torque. As much as 34 HP and 40 FT-LBS of torque are available through the power band. At 5,000+ lbs., acceleration from a complete stop is challenging. However increasing low-end torque with APR’s Stage I ECU Upgrade, the 3.0 TDI will accelerate with minimal effort. Furthermore power normally drops dramatically from 3,500 RPM to redline, but with APR’s Stage I ECU Upgrade, power is dramatically increased making merging and passing on the highway easier. APR’s ECU Upgrade is the best power per dollar modification for the new 3.0 TDI and gives it just the extra edge these cars lack from the factory without pushing the limits. With factory-like smoothness and drivability, APR’s ECU upgrade will fill the void in an otherwise excellent car.
Beyond power and torque enhancements, APR’s Calibration Engineers were able to increase the vehicles acceleration rate through other calibrations changes. Takeoff limiters are reduced resulting in a more responsive pedal without altering overall throttle pedal sensitivity.
Increased Fuel Economy:
APR’s Calibration Engineers paid close attention to several parameters directly related to fuel economy, especially while cruising at highway speeds. Depending on your driving style and fuel quality, you may see better miles per gallon!
Speed Limiter Removed:
APR’s ECU upgrade increases the vehicle’s top speed limiter for blistering sprints around the track or across the Autobahn without the speed limiter shutting down your fun!
Left Foot Braking:
APR’s Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped 3.0 TDI’s throttle input is disabled while pressing the accelerator and brake at the same time. Left Foot Braking, a common motorsport driving technique, allows the driver complete control over the vehicle’s throttle and braking system, which may give the vehicle the edge it needs at the track. As is with all features APR adds to the ECU, this feature may be removed upon request.

APR EMCS Programs and Features
APR’s patented EMCS, Enhanced Modular Chipping System, brings selectable programs and features to your factory ECU, all without the need to purchase external hardware. Other companies have attempted to imitate EMCS with clumsy external switching devices that only replace or multiply portions of a “base” calibration. However, EMCS has the ability to completely rewrite the entire operating map data, giving each map a complete set of calibration changes. APR’s EMCS features and programs modes are activated via your OEM cruise control buttons. Your cruise control will continue to function as normal.
Program switching allows the user to cycle though different engine calibrations and operating modes all without the need for external hardware.
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 Mode:
By selecting performance mode, the APR’s performance calibration is enabled giving you all the benefits APR software has to offer!
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.
How to use APR EMCS Programs and Features
To Enable EMCS:
Turn the ignition and cruise control to the on position. Do not start the engine.
To Cycle through APR Programs:
Hold “SET” on the cruise control stalk. The check engine light will blink in sets of one to four blinks to indicate programs one through four. Release “SET” during this sequence to select a program. The vehicle may be started.
To use Fault Code Erase:
Hold “RESUME” on the cruise control stalk. The check engine light will begin to blink. Release “RESUME” when the check engine light is flashing in groups of one blink per second. Fault Codes will be cleared.
The APR Development Difference
APR ECU Explorer:
APR’s proprietary ECU Explorer gives APR’s Calibration Engineers unparalleled access to the vehicle’s entire engine management system. Typical commercially available data logging tools, used by most tuners, only allow logging up to 12 engine-operating variables at extremely low data rates. These tools are also limited to a small, specific list of variables. APR’s ECU Explorer is capable of logging every variable found within the ECU. It’s capable of logging well over 100 variables at once with data rates as high as 100 samples per second. Synchronous data logging is available for fine-tuning.
APR ECU Composer with APR Live Tuning:
APR’s proprietary ECU Composer is used for altering the engine management system. With full access to every table, map and variable within the ECU, APR’s Calibration Engineers are not limited to a handful of maps as is common for most tuning companies. ECU Composer takes calibration to a new level on the 3.0 TDI with APR’s Live Tuning. APR’s Calibration Engineers can test calibration changes with a single click of a button to instantly monitor the changes, rather than spending several minutes shutting down the vehicle to reflash the ECU. This allows a level of fine-tuning unmatched in the market.
APR ECU Assembly:
APR’s Electrical Engineers have the ability to alter the code structure of the ECU to add features not available from the factory. On the highly modified end, this allows APR to increase torque levels as if intended by the OEM. For most 3.0 TDI owners, the advantage of this ability is the addition of APR’s patented EMCS Functions. EMCS puts the control of the engine’s operation at your fingertips and allows for additional features and options to be installed to your ECU.
