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) with IE's Stage 2 TCU tune increases shift speed, torque limit maps, line pressure, and launch control functions, to further deliver increased performance. As a result, horsepower and torque levels are raised and acceleration is greatly improved to create complete and well-rounded drivetrain performance from your Audi RS5 or RS4.

DRIVING ENHANCEMENTS

HIGH PERFORMANCE TRANSMISSION TUNING

VARIABLE LAUNCH CONTROL

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.

POWER WHEN YOU WANT IT

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.

OPTIMIZED SHIFT POINTS

Stage 2 TCU remaps each gear's RPM limits for the fastest possible acceleration by shifting at the optimal points to keep the engine in peak torque/power output. This strategy pulls the car through the powerband as quickly as possible with incredible improvements in acceleration and G-forces. 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 when you want it.

DEVELOPMENT

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.
