APR - ECU Upgrade - Audi B8.5 A4, C7 A6 2.0T TFSI Valve Lift - Including Flex Fuel Vehicles
APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.0T EA888 Gen 2 engine with Audi Valve Lift! 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. 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.
Stage I ECU Upgrade:
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 284 horsepower and with 334 ft-lbs of torque 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 57 horsepower and 85 ft-lbs of torque. By adding E85 to the tank on the Ethanol compatible variants, automatic Ethanol map blending adds even more power, resulting in 85 horsepower and 135 ft-lbs of torque. The increase in power directly translates to an exceptionally quicker and more enjoyable vehicle.
By simply adding an APR downpipe exhaust system, APR's Stage II software takes performance even further. on 93 AKI fuel peak figures of 302 horsepower and 334 ft-lbs of torque were achieved. Again, by adding E85 on flex fuel compatible variant, 318 horsepower and 405 ft-lbs of torque was achieved!
K04 ECU Software:
Using 93-octane fuel, the APR K04 Turbocharger System produces an astonishing 344 horsepower and 369 ft-lbs of torque. Unlike the factory turbocharger, power stays strong and doesn’t dramatically taper towards the vehicle’s new 7,100 RPM redline. Ethanol 'flex fuel' compatible engine variants can take advantage of automatic E85 map blending to acheive up to 374 horsepower and 408 ft-lbs of torque simply by filling the tank! APR’s calibration experts have safely maximized the full power potential of the turbocharger unit, while keeping reliability at the forefront of their calibration strategies.
The ECU’s MED 17 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! Ethanol 'flex fuel' compatible engine variants can take advantage of automatic E85 map blending to add power simply by filling the tank.
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
