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.

AGGRESSIVE

3400 RPM

3800 RPM (W/AMAX)

RACE

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.

A4 B9 IE stage 1 ecu tune with IE intake and intercooler

It has been awesome the installation process was extremely easy. It really woke up the sound of the car and the performance noticeably. 0-60 is definitely quicker and the car is super fun to drive. The tune increased the sound of the intake and the turbo as well.

Real Review - Real Results

Stage 1 ECU: Tune was fast and smooth while enabling the car to shift on its own. Found an error in both sport/drive mode which prevented the car to shift under WOT from 5th to 6th gear with the DSG. Error was not with the ECU tune rather a stuck injector in cylinder three. Fix as recommended from Audi was 1 can of BG44K. After driving around for nearly 20 minutes under careful acceleration, I did a WOT pull with no shifting issues.

TCU Tune: Please before purchasing any tunes for the B9 A4, be sure to purchase the TCU tune. Little is known bout the DL382 gear box can handle only 300nm. The tune completely fixes the tuning and makes the care safe to drive.

Stage 2 ECU Tune: Do yourself a favor and buy either a catless or HFC downpipe. The added 20 or so HP is noticeable and it gives the car a much better tone. After all modifications, you are looking at a mildly tune B9 S4. While the A4 cannot compete with the S4, most people keep the S4 stock and a stage 2 tuned A4 will surely outperform.
