APR Stage 1 ECU Remap 2.5TFSI - RS3 8P/TTRS 8J

APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.5 TFSI. 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 on early ROW models and through APR's CCD on newer models. 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 on select models.

The APR Stage 1 ECU Upgrade gives you higher peak numbers of 410 horsepower and 606NM. of torque, and gains of up to 76 horsepower and 129NM are available throughout the power band!

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.
