    BMW E46 GM 5L40-E Siemens GS20 TCU Tune

    Greetings and Happy Holidays

    Is there someone capable and qualified with the precise information to tune a GM Siemens GS20 Transmission control module?

    I am in the process of obtaining the factory binary file of the GS20 in my 2000 BMW E46 328ci and will post once available

    EGS unit PN# 24607506056
    ZB# 7506056

    BMW GM A5S360R (5L40-E).

    Regards,
    Mark
