IE TCU Performance Transmission Tune For B9 Audi A4/A5/Q5 2.0T

A tuned engine deserves a transmission calibration that matches it. The factory Audi B9 DSG/S-Tronic was developed for mass-market shift comfort — which means slow, hesitant, inconsistent gear selection that undermines the gains delivered by any engine calibration. The iE TCU Tune for the B9 A4 and A5 synchronizes transmission behavior with iE Stage 1, 2, and 3 engine calibrations — delivering faster, more decisive shifts, smarter gear selection, and a drivetrain that functions as a single coordinated system for the first time. 

The iE Transmission Tune for your Audi turbocharged B9 A4, A5, or Q5 2.0T delivers increased power, faster shifts, variable launch control and additional transmission performance features. When paired with the matching ECU tune, acceleration times will greatly improve turning your tuned turbocharged engine into a fully rounded performance machine.

PERFORMANCE MATCHED

Unlock the full potential of your iE B9 2.0T Stage 1 and Stage 2 engine (ECU) tunes 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.

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.

AMAX mode keeps both clutches partially engaged during full-throttle gear changes, eliminating the power interruption between gears. Acceleration continues uninterrupted from launch through redline. Combined with the kickdown switch at full throttle, this delivers a level of acceleration continuity that factory transmission behavior cannot approach. 
 

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.

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.

LEADING FEATURES

• 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
• Enables gear display -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.
