Product Overview


APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.0 TDI 8v PD, 16v PD and 16v CR. APR’s ECU upgrade is available 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 on select vehicles.

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.

Volkswagen Group’s 2.0 TDI is found in many vehicle makes and models in the Audi, Volkswagen, Seat and Skoda lineup with an 8 and 16 valve Pumpe Düse and 16 valve Common Rail injection system. Over 75 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 on each variant. 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 horsepower and +50 FT-LBS of torque with no other modifications necessary.

Acceleration Enhancements:
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.

Speed Limiter:
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.
