APR 3.6L FSI VR6 ECU Upgrade

Automobile Magazine Review of APR Software

APR is pleased to present the ultimate ECU Upgrade for the 3.6L FSI VR6 with Bosch MED17 Engine Management.

After long nights and many hours of testing, developing and more testing, we’re 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 throttle response and more power across the entire power band.

APR’s 3.6L FSI VR6 ECU Upgrade is an expertly recalibrated engine control strategy that primarily remaps the engine’s air fuel ratio and ignition timing, within the factory Bosch MED17 ECU, 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. Available in octane-specific variations, APR’s calibrations allow you to take advantage of fuel quality available in your area. APR’s patented EMCS functionality puts the control of your engine’s operation at your fingertips 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 287 HP/274 FT-LBS on 93 (R+M)/2 octane and up to 294 HP/276 FT-LBS on 100 (R+M)/2 octane race fuel. As much as 14 HP and 24 FT-LBS of torque are available through the power band. APR’s ECU Upgrade is the best power per dollar modification for the new 3.6L FSI VR6 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.

rabbitAcceleration Enhancements:
Beyond power and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the 3.6L FSI VR6 through other calibrations changes. Throttle and ignition delays are removed resulting in a more responsive pedal without altering overall throttle sensitivity.

ecoIncreased 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!

vmaxSpeed 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 BrakingLeft Foot Braking:
APR's Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped 3.6L FSI VR6’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 3.6L FSI VR6 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 comple

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

StockStock 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.

PerformanceAPR Performance Modes:
APR's octane-specific calibrations are available for various premium and race fuels around the world. Each performance mode is a comple

y new calibration, altered specifically for the characteristics of the fuel quality selected.

fault code eraseFault 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 lockoutSecurity Lockout:
Security lockout prevents unauthorized individuals from using APR's EMCS functionality. When enabled, APR's EMCS features will appear comple

y invisible until a user specified 2 to 4-digit security code is entered.

anti theftAnti-Theft:
When activated, Anti-Theft disables throttle input, even if the factory key is used. The vehicle will be immobilized until a user specified 2 to 4-digit security code is entered.

Valet ModeValet Mode:
APR's Valet Mode protects your vehicle from becoming an expensive toy for unauthorized individuals. By enabling Valet Mode, the vehicle's engine and top speed will be greatly limited.

APR Mobile

APR Mobile is a simple yet powerful tool designed to enhance the APR tuning experience.

The APR Development Difference

APR ECU ExplorerAPR 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 ComposerAPR 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 3.6L FSI VR6 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 AssemblyAPR 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 add forced induction to naturally aspirated vehicle as if intended by the OEM. However, for most 3.6L FSI VR6 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.
