APR Audi A4/A5/Q5 3.0 TFSI ECU Upgrade
APR 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.
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 ECU Upgrade
The APR Stage I ECU Upgrade gives you higher peak numbers of 436 horsepower and 372 ft. of torque, but also gains of up to 168 horsepower and 128 lb-ft are available throughout the power band with 93 AKI fuel! Even more was acheived with higher octane race fuel. 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 of 184 horsepower over stock, a second dropped sprinting from 0-60 mph and over 7 seconds faster in a 62-124mph sprint! Software is included as a free upgrade for APR Stage I customers with the purchase of an APR Supercharger Pulley Upgrade.
Beyond horsepower 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, throttle lag commonly noticed at slow speeds and while reapplying throttle has been reduced.
Increased Fuel Economy:
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.
Left Foot Braking:
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.

|- 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 VAG. | RON = ROW Fuel Grades | AKI = NAR North American (RON+MON)/2 Fuel Grades.|
|- Reported wheel figures measured using APR's in-house Dynapack Dynamometer with a US Spec Q5 (272 PS model), using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications.|
