iE's B9 2.9T ECU Tunes are fully realized performance calibrations that deliver incredible power figures and endless smiles. However, the engine is only part of the fun as your transmission is also in charge of delivering the power to the road. Upgrading your transmission computer (TCU) tune increases shift speed, torque limit maps, line pressure, and launch control functions, to further deliver increased performance. As a result, the iE TCU Stage 2 Tune will significantly transform every aspect of your RS5, or RS4, delivering faster launches, higher Gs, and further improved acceleration.

Stage 2 TCU is for use with either Stage 1 or 2 ECU tune.

Important Notice: 2021+ models are equipped with advanced security locks that prevent Stage 2 Transmission tuning. iE calibrators are currently working on bypassing the security to offer TCU tuning for all model years. In the meantime, iE TCU Stage 1 is fully compatible and will allow full power output from the ECU tune.

This complete TCU remap is packed with features that allow you to take full advantage of the increased power delivery from your ECU tune in any situaiton. Power is always on demand by unlocking 8th gear in sport mode, removing gear drop pauses, turning on 1st gear downshift without coming to a full stop, and removing take-off throttle lag. Additionally, annoyoing gear-hunting situations are elliminated with all-new drive mapping to keep the engine and transmission in the proper gear throughout the power range.

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.

User adjustable launch control delivers chest pounding launches that will significantly lower your 0-60 ond quarter-mile times. Three different launch RPMs (street, aggressive, or race) are included to dial in the fastest launch for your vehicle and tire setup.
