iE’s Performance Transmission Tune for your Audi B9/B9.5 S4, S5, or SQ5 3.0T delivers unmatched acceleration and power delivery. 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.

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.

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.

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.

iE’s POWERlink Suite Tuning App gives you the freedom to quickly flash your new iE ECU or TCU Tune from your phone. Simply plug your POWERlink into the vehicle’s OBD-2 port and follow the app directions, it’s that easy!

If you are purchasing along with an iE ECU Tune, you do not need to purchase two POWERlink cables. One cable can flash both your ECU and TCU tunes.
