IE Audi 2.0T TSI / TFSI EA888 Gen1/2 Performance ECU Tune | Fits Audi B8/B8.5 A4, A5, Allroad, & C7 A6

Unlock the performance potential of your Audi with the Integrated Engineering (IE) 2.0T TSI / TFSI EA888 Performance ECU Tune, designed for compatible Audi B8/B8.5 A4, A5, Allroad, and C7 A6 applications. Developed for the longitudinal turbocharged 2.0L engine platform, this performance software upgrade delivers increased horsepower, stronger acceleration, improved throttle response, and flexible tuning options for stock and modified vehicles.

With advertised performance reaching up to 290 HP on the factory turbocharger and 367 HP with a compatible K04 turbo upgrade, IE offers a progressive tuning solution that allows enthusiasts to increase performance as their vehicle evolves.

The IE tuning platform includes Stage 1, Stage 2, and K04 performance calibrations. Stage 1 is designed to provide noticeable power gains without requiring additional hardware, while Stage 2 takes advantage of upgraded intake, intercooler, and downpipe components to maximize the factory turbocharger's performance. For owners seeking additional power, the K04 calibration supports a compatible upgraded turbocharger configuration.

Featuring POWERlink Bluetooth mobile tuning, the system allows drivers to flash supported ECU calibrations directly from an Apple or Android smartphone. The POWERlink interface connects through the vehicle's OBD-II port and provides access to octane switching, live engine gauges, data logging, diagnostic functions, and compatible tuning updates.

For supported factory Flex-Fuel Audi models, IE also offers TrueFlex ethanol tuning, allowing the ECU to automatically adjust engine calibration according to the fuel and ethanol blend in the tank. This feature takes advantage of the factory ethanol sensor found on compatible 2013–2016 B8 2.0T Flex-Fuel applications.

Additional features include optional Exhaust Crackle for Stage 2 and K04 calibrations, dedicated tuning options for the IE Performance Intake Manifold, and revised engine speed limits for supported manual-transmission configurations.

Manufactured by Integrated Engineering, this ECU tune provides a comprehensive performance upgrade for Audi enthusiasts seeking increased engine output, convenient mobile flashing, and an adaptable tuning platform.

ECU Tuning Stages

Stage 1 ECU Tune

The IE Stage 1 ECU Tune provides a straightforward performance upgrade for compatible vehicles retaining their factory engine and turbocharger hardware.

Advertised Performance Gain: Up to +27 HP

Stage 1 optimizes the factory engine calibration to improve acceleration and power delivery without requiring additional performance components.

An aftermarket intake can be installed to support airflow and provide a more distinctive turbocharger sound, but it is not required for the standard Stage 1 configuration.

Stage 1 Highlights:

• Compatible with factory engine hardware.

• No mandatory performance hardware upgrades.

• Supports applicable 91- and 93-octane calibrations.

• Compatible with supported IE intake upgrades.

• Includes dedicated calibration options for the IE Performance Intake Manifold.

• Supports future upgrades to Stage 2 or K04 tuning.

Stage 2 ECU Tune

The IE Stage 2 ECU Tune is designed to maximize the performance potential of the factory turbocharger when paired with the required supporting modifications.

Advertised Performance: Up to 290 HP

Stage 2 uses revised engine calibration to take advantage of increased intake airflow, improved charge-air cooling, and an upgraded exhaust flow path.

Required Stage 2 Hardware:

• Compatible performance air intake.

• Upgraded intercooler.

• Compatible upgraded downpipe.

Stage 2 also includes the optional Exhaust Crackle feature, allowing owners to add a more aggressive exhaust character during supported operating conditions.

A compatible cat-back exhaust can further enhance the vehicle's exhaust sound.

K04 Turbo ECU Tune

For enthusiasts seeking maximum performance from the supported upgrade path, the IE K04 calibration is designed for vehicles equipped with a compatible bolt-on K04 turbocharger.

Advertised Performance: Up to 367 HP

The upgraded turbocharger provides additional airflow capacity, allowing the engine to deliver stronger mid-range acceleration and increased performance compared with the factory turbocharger configuration.

Required K04 Hardware:

• Compatible performance air intake.

• Upgraded intercooler.

• Compatible upgraded downpipe.

• Supported K04 turbocharger.

The K04 tuning option supports applicable 91-, 93-, and 100-octane fuel calibrations.

An optional Exhaust Crackle feature and dedicated IE Performance Intake Manifold calibration are also available.

TrueFlex E85 Ethanol Tuning

Integrated Engineering TrueFlex technology is designed to take advantage of the factory ethanol-content sensor installed on compatible 2013–2016 Audi B8 2.0T Flex-Fuel vehicles.

Rather than requiring the driver to manually select a fixed ethanol calibration whenever the fuel blend changes, TrueFlex allows the ECU to automatically adjust supported tuning parameters according to the detected ethanol concentration.

This provides compatibility with supported 91/93-octane gasoline, E85, and varying gasoline-ethanol blends.

Important: TrueFlex support requires the appropriate factory Flex-Fuel hardware and compatible ECU software. Do not assume ethanol tuning compatibility with non-Flex-Fuel vehicles or other Audi applications unless confirmed by Integrated Engineering.

Optional Exhaust Crackle

The optional IE Exhaust Crackle feature adds a motorsport-inspired exhaust sound during supported deceleration, throttle release, and gear-change conditions.

This feature is available with compatible Stage 2 and K04 tuning configurations.

A suitable cat-back exhaust can complement the sound characteristics of the selected calibration.

IE Performance Intake Manifold Tuning

All supported IE Stage 1, Stage 2, and K04 ECU tuning stages include dedicated calibration options for vehicles equipped with the IE Performance Intake Manifold.

These manifold-specific files are designed to accommodate the upgraded intake manifold's larger plenum, optimized runner configuration, and removal of the factory runner flaps.

Select the appropriate manifold calibration according to the exact hardware installed on your vehicle.

Hardware Upgrade Guide
