APR 3.0T SUPERCHARGED V6 ECU UPGRADE (B8 S4&S5 / B8.5 S4&S5 / A6 / A7 / Q5 / SQ5 / Q7)

APR Stage 1 ECU Tune

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’s ECU upgrades are one of the best horsepower-per-dollar modifications for the 3.0T 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 up to 372 ft-lbs of torque and 444 horsepower with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 98 ft-lbs of torque and 134 horsepower. Even higher figures were achieved using race fuel. The increase in horsepower and torque directly translates to an exceptionally quicker vehicle.

Gains over Stock 

Stage 1 – 91 Octane gas – 433HP / 364 Ft-lbs of Torque = 124 HP Gain over stock / 90 Tq over stock

Stage 1 – 93 Octane gas – 444HP / 372 Ft-lbs of Torque = 134 HP Gain over stock / 98 Tq over stock

Stage 1 – 100 Octane gas – 459HP / 380Ft-lbs of Torque = 150 HP Gain over stock / 155 Tq over stock 

Acceleration Enhancements

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.

Speed Limiter   

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.

30 Day Money Back Guarantee

All APR ECU Upgrades include a 30-day money back guarantee with no questions asked. If for any reason the owners is dissatisfied with the APR ECU Upgrade, they may return to the place of purchase for a full refund, provided they are within the 30 day period from the time of the initial purchase. **Refund is on ECU Software only, there is a labour fee applied to flash the vehicle back to factory
