APR ECU Upgrade - 3.0T TFSI - C6 A6 & Q7 - Simos 8.3

APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 3.0 TFSI!

APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 3.0T engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through APR's CCD Simos 8.3 models.

APR ECU Upgrade Stages

APR’s ECU Upgrades are available in multiple stages, supporting various octanes both with or without any hardware modifications. Specific software is available for use with APR's Supercharger Drive Pulley upgrade, while all stages are fully compatible with an upgraded intake, supercharger cooler, exhaust system, or other minor bolt on modifications.

APR Stage I ECU Upgrade

The APR Stage I ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 356-388 HP with 349-364 FT-LBS of torque. Gains as high as 81-114 HP and 65-91 FT-LBS of torque are available throughout the power band, making the vehicle exceptionally quicker in all scenarios. To get more power, the vehicle can be outfitted with an upgraded intake, supercharger cooler, exhaust system and other small modifications without requiring any new modification to the ECU. To run APR's Supercharger Drive Pulley upgrade, APR’s Stage II ECU Upgrade is required.

For the next step in increased power, APR Stage II ECU Upgrade is available for use with APR's Supercharger Drive Pulley upgrade.

APR Stage II ECU Upgrade

The APR Stage II ECU Upgrade is the next step towards making more power! This upgrade requires an APR Supercharger Drive Pulley, and produces 375-408 HP with 373-389 FT-LBS of torque. Gains as high as 100-135 HP and 79-107 FT-LBS of torque are available throughout the power band. An APR's Supercharger Drive Pulley upgrade is required. No ECU modification is necessary to run an upgraded intake, supercharger cooling system, exhaust system, or other small engine modifications.

APR ECU Upgrade Standard Features:

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. 

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.

Motorsport Rev Limiter: APR’s Motorsport Rev Limiter allows the engine to reach max RPM without the ECU slowing down acceleration nearly 150 RPM earlier. The result is more power to redline and a definable redline feeling as seen on Audi Quattro GMBH vehicles such as the RS4, RS5 and R8.

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.
