Easy Install From Home: 

IE's POWERlink Cable and Flash Wizard software gives you the freedom to quickly flash your new IE ECU Tune. Simply plug your POWERlink into the vehicle's OBD-2 port and follow the on-screen directions, it's that easy

Variable Launch Control

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.

Performance Matched

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.

One Tune For All Stages

IE’s ZF8 AL552 TCU tune is all-inclusive without any unnecessary upgrades or additional charges for future ECU Tune upgrades. All features and optimizations are included for any level of hardware or performance stage, one cost and you are covered for all and any future upgrades.

Driving Enhancements

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.

Rpm Limit Raised

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!  

Fast Downshifts

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.
