With this update, KESS3 and Powergate allow you to work in OBD mode on Bosch ZF AL551\/8HP55 TCUs, providing a direct and practical connection for reading and writing Tiptronic automatic transmissions fitted to a wide range of Audi and Volkswagen applications. These units equip cars and SUVs produced from 2008 through to post-2020 models, paired with 2.5 FSI, 4.2 V8 FSI, 6.3 W12 FSI, 2.0 TFSI, 3.0 V6 TFSI, 4.0 V8 TFSI and 3.0 TDI engines. <\/p>

A solution designed for working on automatic transmissions fitted to sports and high-performance models as well. The diagnostic-port connection simplifies operations, reduces the steps required to access the TCU and makes the read and write workflow fast and straightforward. <\/p>

The real benefits for the workshop:<\/strong><\/p>

  • Direct connection in OBD mode<\/li>
  • Greater practicality in TCU management<\/li>
  • New opportunities on high-performance Audi and Volkswagen models<\/li>
  • Coverage of widely used applications in key international markets<\/li>
  • Management available with Powergate<\/li>
  • Possibility to expand the range of powertrain services offered<\/li><\/ul>

    This new support enables workshops and tuners to achieve integrated ECU and TCU management, combining engine ECU remapping with automatic transmission remapping and offering complete solutions for sports applications with high power and torque values.<\/p><\/div><\/div><\/div><\/div><\/div><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
