The IE Transmission Tune for your Audi turbocharged B9 S4, S5, or SQ5 3.0T delivers increased power, higher RPM limit, 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.
Stage 1 or higher ECU Tune is required to run this transmission tune.
IE's B9 3.0T ECU Tunes are fully realized performance calibrations that deliver incredible power figures. Without a matching TCU tune, the transmission can feel unmatched to the new ECU tune -leaving speed on the table. Furthermore, the TCU upgrade modifies shift speed, torque limit maps, line pressure, and launch control functions, to fully match your ECU calibration. As a result, horsepower and torque levels are raised and acceleration is greatly improved to create a complete ECU & TCU performance package.
The IE ZF8 AL552 TCU Tune includes a variable launch control to deliver chest pounding launches from a stop. 3 different launch RPMs (street, aggressive, or race) are included to dial in the fastest launch for your vehicle and tire setup. With the optimized launch mode set in your TCU, you can launch to the moon knowing your tires will put down the maximum power needed for the fastest launch.

Required to flash your new tune, IE's DIY Flash Tool allows you to quickly upload your tune from your own garage or driveway. This OBD plug-in device is easy to use with a Windows powered laptop and WiFi connection. Your new tool also includes the abilities to switch between multiple octane files (available separately), reading and clearing diagnostic codes, upgrading Stages, or flashing back to stock.
IE's fully proven transmission software allows the full performance experience from your supercharged 3.0T engine while retaining factory comfort and reliability. IE's own tuning technology suite is used to completely reverse-engineer the factory transmission mapping, allowing our software engineers access to realign all safety protocols for the new TCU calibration. Every tune parameter undergoes months of testing on our in-house dyno systems to verify all correct conditions for peak power delivery and reliability. All driving behavioral maps undergo thousands of miles of testing and a variety of users were polled to develop the ideal driving behavior.
The factory transmission calibration has many performance short comings leaving much to be desired by the enthusiast driver. IE software engineers have completely reworked the transmission tune computer with performance driving in mind. This new transmission calibration keeps the engine and transmission in the proper gear throughout the power range in a sported driving scenario without any annoying gear-hunting situations.
The factory ECU and TCU tune has a maximum rev limit of 6500RPM, however in full throttle pulls 1st and second gear are short shifted, leaving power on the table. IE's complete TCU tune raises the transmission to a 6500RPM limit across the board for the best powerband in every gear. This extra power band will not only rev out longer, but will take full advantage of the extra top-end power on ethanol tunes sending your car down the track even faster!
When engaging full throttle from a cruising speed, the factory TCU calibration has longer pauses when dropping multiple gears. This delay causes a large lag when you are asking for immediate power. IE's performance calibration removes these delays when dropping down multiple gears, delivering near-instant boost and power when you demand it.
