IE Audi 2.0T TSI Gen 3 Performance ECU & TCU Tune | Fits Audi B9 A4 & A5 Quattro

Unlock hidden performance from your Audi B9 A4 or A5 2.0T with the IE Performance ECU Tune. This advanced calibration delivers significant horsepower and torque gains over stock while maintaining smooth daily drivability and reliability. Flash your new tune easily from your Apple or Android device using IE’s POWERlink Bluetooth technology — no workshop visit required.

Leading Features

Innovative mobile tuning via the POWERlink Bluetooth app (Apple & Android)
Thrilling power and acceleration improvements
TrueFlex flex-fuel tuning included (adapts to ethanol blends automatically)
Multiple octane files supported: 91, 93 & 104 AKI (95, 98, 108 RON)
Stage 1 for stock and basic bolt-on hardware
Stage 2 option for aftermarket downpipe support
Optional matching transmission (TCU) tune available

Easy At-Home Tuning

The IE POWERlink Bluetooth dongle plugs into your vehicle’s OBD-II port and communicates with the POWERlink app to flash your new tune, switch fuel maps, perform diagnostics, view live data, and more — all from your phone.

TrueFlex Ethanol Support

Ethanol is high-octane rocket fuel, and IE’s TrueFlex tuning automatically adjusts for ethanol content in real time. This allows you to run ethanol blends smoothly and safely while maximizing performance gains.

ECU Tuning Stages

Stage 1 adds impressive horsepower and torque gains with no required hardware upgrades, ideal for stock or lightly modified cars. Stage 2 unlocks further potential when paired with an aftermarket downpipe, yielding higher peak power and stronger acceleration across the powerband. :contentReference[oaicite:4]{index=4}

TCU TUNE

HIGH-PERFORMANCE TRANSMISSION SOFTWARE

PERFORMANCE MATCHED

Unlock the full potential of your iE B9 2.0T Stage 1 or Stage 2 engine (ECU) tune with our matching transmission (TCU) tune. Without it, your power gains and performance features are limited, leaving untapped acceleration and power on the table. Upgrading to the iE TCU tune significantly enhances shift speeds, eliminates torque limiters, increases line pressure to prevent transmission slip, and introduces user-adjustable launch control functions. Experience a dramatic enhancement in launch power, pulling force, shift responsiveness, and overall acceleration.

Lightning fast shifts -further improves acceleration and 0-60 times
Full power from ECU tunes -removes power robbing torque limiters
Adjustable launch control -dial in the perfect launch for your setup
Dash always displays current gear in drive/sport modes
Full torque during AMAX shifts -torque reduction programming removed

Important note: Compatible with 2017-2020 DL382 DSG "Gen 1" transmissions only. TCU tune is currently incompatible with all 2021+ "Gen 2" TCU versions. In some rare cases, 2019 and 2020 model year vehicles may be equipped with unsupported Gen 2 variations.

VARIABLE LAUNCH CONTROL

Experience chest-pounding launches with our iE transmission tune featuring adjustable launch control. Tailored for optimal performance, choose from three distinct launch options: street, aggressive, and race. Each option increases the launch RPMs, allowing you to customize the launch experience to suit your vehicle and tire setup for the best grip and take-off power. Each launch setting offers two RPM launch and AMAX options, easily controlled by the throttle pedal:

Apply 100% throttle input without engaging the kickdown switch to launch from the minimal chosen RPM without AMAX.
Engage full pedal pressure while activating the kickdown switch to launch with an additional 400RPMs and trigger AMAX in all shifts, delivering the most aggressive launch and pull strategy.

LAUNCH SETTING	MINIMUM RPM	MAXIMUM RPM
STREET	3000 RPM	3400 RPM (W/AMAX)
AGGRESSIVE	3400 RPM	3800 RPM (W/AMAX)
RACE	3800 RPM	4200 RPM (W/AMAX)

Note: AMAX is an advanced shift programming that greatly improves accleration by maintaing power to both transmission clutches simutaniously while transitioning between gears. This feature delivers a strong advantage in a competitive drag racing type scenario.

DRIVING ENHANCEMENTS

The factory transmission calibration often falls short in meeting the demands of performance enthusiasts, leaving much to be desired. iE's TCU tune addresses these limitations by entirely reworking the transmission drive-mapping strategy, catering specifically to the enthusiast driver. Beyond driving improvements, our TCU tune introduces additional features designed to enhance the driving experience:

Reduced take-off lag time from a standstill.
Enables gear display on the dashboard in both drive and sport modes.
Eliminates factory torque pull during AMAX shifting.
Increases protection by automatically reducing engine power if transmission temperatures climb too high.
