Important Notice: 2021-2024 (B9.5) model years have limited support. Some transmissions are equipped with advanced security locks and cannot be unlocked for tuning.

This cutting-edge TCU tune transforms your turbocharged Audi into a complete and fully realized powerhouse. Experience seamless integration with lightning fast shift speeds, enhanced torque maps, eliminated clutch slip, and hard hitting launch control -all designed to work in perfect harmony with your iE engine tune. Unlock the full potential of your Audi with the ultimate TCU tuning suite.
LAUNCH CONTROL
The iE 3.0T TCU Tune includes a reworked launch control to deliver chest pounding launches from a stop. 2021+ (B9.5) years include an optimized launch control setting, resulting in dramticially improved 0-60 times in any scenario. 2017-2020 (B9) years include user-adjustable settings (street, aggressive, or race) to dial in the launch torque for your power and tire combination.
DRIVING ENHANCEMENTS
The factory transmission calibration has many performance shortcomings, leaving much to be desired by enthusiast drivers. iE software engineers have completely reworked the transmission tune computer for performance driving, ensuring the engine and transmission remain in the proper gear without any annoying gear-hunting situations. iE ECU tunes include differences in shift point and throttle mapping between drive and sport modes, allowing for 7th and 8th gears in all modes and eliminating delays when dropping multiple gears, delivering near-instant boost and power on demand.
OPTIMIZED SHIFT RPM
The iE TCU Tune remaps each gear's RPM limits for the fastest possible acceleration. Every gear will shift at the optimal points to pull the car through the powerband as quickly as possible for the fastest conditions on road, track, or drag strip with incredible improvements in acceleration and G's. These optimized shift points occur when in drive mode, sport mode, and AMAX. The transmission limit remains 6500 RPM in all gears in manual mode, retaining complete manual control over the shift points.
