APR 3.0 TDI ECU Upgrade
APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 3.0 TDI V6. APR’s ECU upgrade is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU. APR’s EMCS functionality puts the control of the engine’s operation at your fingertips and allows for additional features and options to be installed to the OEM ECU.
The ECU’s Bosch EDC engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.
APR's Calibration Engineers spent months calibrating the engine management system, including many hours of chassis dyno development. With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque across the entire power band. APR’s ECU Upgrade increases boost pressure, optimizes fuel injection and more to produce higher output!
APR’s ECU Upgrades provides an excellent leap in horsepower and torque while retaining built in safety features. This results in an exciting and powerful upgrade.
Stage I ECU Upgrade
Volkswagen Group’s 3.0 TDI is found in many vehicle makes and models in the Audi and Volkswagen lineup. Over 45 engine codes exist today with hundreds of ECU revisions across the world. In many cases, the same engine is offered in high, medium and low output models simply through factory ECU tuning alone. However, some models are more capable than others due to the supplied components such as the turbocharger, fueling system and other emissions related pieces.
The APR ECU Upgrade maximizes output in each scenario. Depending on the vehicle and attached components, torque and power output with APR’s ECU upgrade will vary. APR’s Stage I ECU Upgrade can result in a gain of +30-60 horsepower and +30-90 FT-LBS of torque with no other modifications necessary.
Beyond horsepower and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle through other calibrations changes. Injection delay is reduced resulting in a more responsive pedal without altering overall throttle sensitivity. Furthermore, throttle lag commonly noticed at slow speeds and while reapplying throttle has been reduced.
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 driving style and fuel quality, better miles per gallon may be achieved.
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 the fun.
Left Foot Braking:
APR's Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped vehicle'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.
The APR Development Difference
APR DirectPort Programming:
APR’s DirectPort Programming is now available! Any APR Dealer in the world, connected to the Internet, has direct access to APR’s latest ECU upgrades for loading directly over the vehicle's OBD-II port. This completely eliminates the need to remove and open the ECU for currently available files and can be uninstalled at any time!
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 with far more variables logged at once, at very high data rates.
APR ECU Composer:
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.
APR ECU Assembly:
APR’s Electrical Engineers have the ability to alter the code structure of the ECU. Through code levels changes, APR's Engineers are able to add features to the ECU. Other changes allow higher torque limits than those achievable through only modifying calibration data or using piggyback devices as is the case for many tuners. This allows APR's engineers to often not require transmission software to meet or exceed advertised gains. On the highly modified end, this often allows APR to make turbo upgrades operate without the need for external manual controllers.

How to purchase
Please use the APR Dealer Locater Tool to locate an APR Dealer, confirm availability and schedule an appointment.
Please note vehicle manufacturers issue many ECU part numbers and revisions throughout their vehicle lineup. As such, some ECUs may be temporarily unavailable as new parts and/or revisions are released. If the vehicle’s ECU part number and revision is known, availability can be checked at any APR Dealer.
