APR Presents the B8.5 A4 / A5 / Q5 & C7 A6 2.0 TFSI VL (Flex/Non Flex) ECU Upgrade! APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.0 TFSI 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 patented EMCS functionality puts the control of your engine’s operation at your fingertips and allows for additional features and options to be installed to your OEM ECU. The Bosch MED17 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 from idle to redline.
APR’s ECU Upgrade increases turbocharger boost pressure and optimizes cam timing, valve lift, ignition 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. Using APR’s proprietary high-speed data logging suite, the calibration team closely monitored the effects of these changes to ensure a powerful ECU upgrade without derogating the engine’s drivability or reliability. APR’s ECU Upgrade will provide an excellent leap in power and torque while retaining OEM knock control sensitivity and other built in safety features. The result is safely achieved power, optimized for various fuel grades found around the world. We call it Performance Without Compromise! 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, a free upgrade to existing APR Stage I customers, takes performance even further. 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! APR’s ECU upgrade is the best power per dollar modification for the new 2.0 TFSI engine and takes the vehicle’s performance to similar levels typically reserved for higher output, sporty models, without pushing the limits. With factory-like smoothness and drivability, APR’s ECU upgrade will fill the void in an otherwise excellent vehicle. Beyond power and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle through other calibrations changes.
Ignition delay is reduced resulting in a more responsive pedal without altering overall throttle sensitivity. Furthermore, drivability was greatly improved by reducing the throttle lag commonly noticed at slow speeds and while reapplying throttle after decelerating. 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! 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! 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.
As is with all features APR adds to the ECU, this feature may be removed upon request. E85 only supported on flex fuel supported models. These models have a silver metal intake manifold. Max rev limit TCU controlled on automatic transmissions. APR recommends and tuned with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode. Max increases are based on APR's actual measured stock values and not those reported by VW. Reported wheel figures measured on APR's in house Dynapack Dynamometer with a 2014 A5 (217hp) AWD with 8 speed tiptronic transmission, using SAEJ1349 correction and an average of multiple runs. Crank figures estimated based on the measured wheel figures. Results will vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, and other modifications. Data collected at the same location via a Racelogic P-Box with ESP/ASR off, Dynamic mode and Sport mode.
