Integrated Engineering Performance Transmission Tune for Audi B9/B9.5 2.9T RS5 & RS4 - Stage 2

Integrated Engineering's Performance Transmission Tune recalibrates the AL552 ZF 8-speed automatic in the 2.9T Audi RS4 and RS5 (B9 and B9.5) to suit an IE engine tune. This is the Stage 2 transmission tune, for use with IE's Stage 1 or Stage 2 ECU tune, and it brings optimised shift points, faster shifts and launch control in every drive mode with user-adjustable launch settings. Line pressure is raised to protect against slip, and the tune is flashed through the OBD2 port with an IE POWERlink V4.

Features

• Optimised shift points for the fastest acceleration, including shift points for HPFP and TrueFlex ethanol files
• Launch control enabled in all drive modes, with user-adjustable launch settings
• Faster shift speed and reduced time for double downshifts
• 7th and 8th gear enabled in Sport mode
• Downshifts into 1st gear without coming to a full stop
• Line pressure increased to protect against transmission slip
• Flashed through the OBD2 port with an IE POWERlink V4, which can also flash an IE ECU tune
