APR dont do the diesel tuning.
They do
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 OEM knock control sensitivity and other built in safety features. This results in an exciting and powerful upgrade.
