APR ECU Software 3.0TFSI S4 S5 B8

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. 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.

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.

Stage 1: APR’s Stage 1 ECU upgrades are one of the best horsepower-per-pound 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 510NM of torque and 441HP with 98 octane fuel. Large gains were seen throughout the power band, including an additional 98NM of torque and 98 horsepower. Even higher figures were achieved using race fuel. The increase in horsepower and torque directly translates to an exceptionally quicker vehicle.

Stage 2: For those demanding more torque, The APR Supercharger Pulley Upgrade is the answer, whether single or dull pulley to unleash the full potential. Spinning the supercharger faster increases air flow and allows for excellent gains over stage I alone. The gain in torque is felt immediately, but the results are present all the way to redline adding up to 147NM and 148HP with 98 RON octane fuel! Stage 2 Software is an additional cost upgrade for APR Stage 1 customers with the purchase of an APR Supercharger pulley upgrade kit.

Key Features:

- Acceleration enhancements! Throttle lag commonly noticed at slow speeds and while reapplying throttle has been reduced.

- De-limited! 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.

- Improved 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.

- 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.
