Performance Transmission Tune

The Integrated Engineering Performance Transmission Tune is a cutting-edge TCU tune for your Audi B9/B9.5 S4, S5, or SQ5 3.0T, designed to transform your turbocharged vehicle into a powerhouse. This tune delivers unmatched acceleration and power delivery through seamless integration, lightning-fast shift speeds, enhanced torque maps, eliminated clutch slip, and a hard-hitting launch control system. Experience dramatic improvements in acceleration and 0-60 times with the reworked launch control. For 2021+ (B9.5) models, an optimized launch control setting is included. For 2017-2020 (B9) models, users can select between street, aggressive, or race settings to dial in launch torque based on power and tire combinations. The software completely reworks the transmission tune computer for performance driving, ensuring the engine and transmission remain in the proper gear without annoying gear-hunting. It also includes distinct shift point and throttle mapping between drive and sport modes, allows for 7th and 8th gears in all modes, and eliminates delays when dropping multiple gears for near-instant boost and power on demand. Each gear's RPM limit is remapped for the fastest possible acceleration, shifting at optimal points to pull the car through the powerband as quickly as possible for the fastest conditions on road, track, or drag strip. Optimized shift points occur in drive, sport, and AMAX modes. The transmission limit remains 6500 RPM in all gears in manual mode, retaining complete manual control. Installation is made easy with the iE POWERlink Suite Tuning App, allowing you to flash the tune from your phone via the OBD-2 port. If purchasing with an iE ECU Tune, one POWERlink cable can flash both. This tune is compatible with Audi S4 (2017-2024* B9/B9.5), S5 (2018-2024* B9/B9.5), and SQ5 (2018-2024* B9/B9.5) models. Important Notice: Some 2021-2024 B9.5 transmissions may be equipped with an advanced security lock. Before purchasing, please verify TCU compatibility by following the provided B9.5 TCU Unlock Guide.
