Transmission Tune 3.0T AL552

The IE Performance Transmission Tune is a TCU tuning suite designed for Audi B9/B9.5 S4, S5, and SQ5 models with the 3.0T engine and AL552 ZF8 transmission. It delivers enhanced acceleration and power delivery through lightning-fast shift speeds, improved torque maps, and eliminated clutch slip.

This tune features a reworked launch control system for powerful launches from a stop. For 2021+ (B9.5) models, it offers an optimized launch control setting for dramatically improved 0-60 times. For 2017-2020 (B9) models, user-adjustable settings (street, aggressive, race) allow for customized launch torque.

The software engineers have remapped each gear's RPM limits for faster acceleration, ensuring optimal shift points for peak performance on road, track, or drag strip. Manual mode retains a 6500 RPM limit for complete driver control. Installation is made easy via the iE POWERlink Suite Tuning App, allowing flashing directly from a smartphone.
