APR Audi C6 A6 and Q7 3.0 TFSI ECU Upgrade

engineAPR is pleased to present the ultimate engine control unit (ECU) upgrade for the 3.0 TFSI V6. APR’s ECU upgrade is 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 on Simos 8.4/8.5 models and through APR's CCD on Simos 8.3 models.

The ECU’s Simos 8 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 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.

APR Stage I and Stage II+ ECU Upgrades


The APR Stage I ECU Upgrade gives you higher peak numbers of 313 horsepower and 323-ft. of torque measured at all 4 wheels, but also gains of up to 95 all wheel horsepower and 75lb lb-ft are available throughout the power band!

For those demanding more torque, The APR Supercharger Pulley Upgrade is the answer. Spinning the supercharger faster increases air flow allowing for higher boost levels and more power. The gain in torque is felt immediately, but the results are present across the entire powerband. Expect gains up to 347 all wheel horsepower with 93 octane fuel! Software is included as a free upgrade for APR Stage I customers with the purchase of an APR Supercharger Pulley Upgrade.
