APR Tuning

APR’s ECU upgrades are available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU.

Your cars’ 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 spend 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 ignition timing, cam timing, lambda 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, optimized for various fuel grades found around the world.

Yes, APR has a DSG tune just for your DQ250 gearbox!

APR is pleased to present the ultimate transmission control unit (TCU) upgrade for the DQ250 Exx & Fxx DSG and S tronic transmissions! APR’s TCU upgrade is available in engine and power level specific variations and is conveniently flashed to the vehicle’s factory TCU through the OBD-II port. APR’s DirectPort Programming Suite allows the end user to customize the TCU upgrade to their individual needs.

APR’s TCU upgrade enhances the driving experience by incorporating many of the same features typically reserved for high-end Audi Quattro GmbH RS models. Under blistering, wide-open throttle acceleration, the transmission shifts even more quickly than before with a higher rev limit. However, during normal, day-to-day driving, the TCU Upgrade delivers a smooth, yet responsive and refined driving experience.

Limited Lifetime Warranty
All APR TCU Upgrades include a limited lifetime warranty against defects in the software, and to provide free updates and reflashes as they become available. Labor or shipping charges are not included in the warranty and are at the discretion of the place of install.

Hi! No you don’t need to purchase any hardware for APR Stage 1 as the tune safely maximises the capabilities of the existing factory hardware. This ensures that your vehicle does not require any modifications that may catch the eye of the local law enforcement but still get the gains that are present in your marques’ higher end vehicles.

APR’s ECU upgrades are one of the best horsepower-per-dollar modifications for your engine. The APR Stage I ECU Upgrade is designed to work without requiring other changes to the vehicle’s hardware. With the ECU Upgrade alone, APR’s Calibration Experts measured higher peak figures of torque and horsepower. Large gains were seen throughout the power band, including additional torque and horsepower. Even higher figures were achieved using race fuel.

Of course, when you’re looking at adding additional APR hardware. The APR Stage II software takes performance even further!
