Transmission Control Unit section of the FBS4 Manager has the following functionalities

• Read and save FBS data

• Set the unit to virgin state

• Personalize with data from file (which you can read and save)

• Personalize without existing personalization data

• Change VIN

• Update the software versions of the donor module in accordance with the original ones

This will allow you to perform a complete TCU exchange, so that the vehicle can start and run properly. One of the many benefits of these procedures is that when adapting transmissions, we do not clone them, we only transfer the necessary Immo-related data (FBS Data), keeping donor’s calibration values.

Supported units

• VGS4-NAG2 7G-Tronic

• VGS-NAG3 9G-Tronic

• VGS-FDCT/VGS2-FDCT

• VGS3-FDCT

• 8-DCT

For details on how to work on each of the Transmission Control Units, please check the dedicated section of this user manual

Procedures may differ depending on your active licenses. Please consult Abrites team for details.

After the transmission is personalized, it is important to ensure that the software versions of the original transmission match those of the donor TCU.

The “Program” button allows you to update the donor TCU’s software versions to align with the original transmission versions.

You have two options: either load your own files(.cff) by browsing your PC, if available, or use our server to program the TCU with the correct software versions.

If you are replacing a TCU (only the electronics) it is important to save a back up of the configuration of the original TCU (Utilities > Save all Config data).

If you are replacing the whole transmission unit (electronics and mechanical part) then you would have to use the configuration that is on the donor TCU.
