    What does the MED9 mapswitch tool do?

    Mapswitch patches a full bench or boot read from the Bosch MED9 engine ECU. This tool covers MED9.1, MED9.1.5. A file larger than 2,197,152 bytes is treated as MED9.1.5, which includes the 2.5 MB RS3 MED9. Virtual reads are rejected, and the immobilizer stays on. You enter the hex address of each map to switch.

    ImmobilizerStays on. The tool does not turn it off

    How do you switch maps?

    Pick one method when you build the file.

    • Pedal: hold the accelerator at 100%, then press the brake to switch.
    • Cruise control: hold the brake or the clutch, then press cruise set to switch.

    Which addresses can you change later?

    None. Map addresses are fixed once you submit. Enter 0 for any map you do not want switched. To find a start address in WinOLS, use how to find map properties. Take a full ECU backup before you flash. You can tune the patched file afterwards.

    EDC15, including EDC15P, EDC15P+, and EDC15VM+, is a separate 512 KB tool: EDC15 mapswitch. Both are on the multimap hub.
