    What does the EDC15 mapswitch tool do?

    Mapswitch (also called multimap) adds three switchable maps to a stock Bosch EDC15 read. This tool covers EDC15P, EDC15P+, EDC15VM+. Upload a bench or boot file of exactly 512 KB (.bin or .bdc), enter the VIN and the 5-digit soft coding from the VCDS engine page, and choose pedal or cruise-control switching. The file is locked to that VIN.

    How do you switch maps?

    Pick one method when you build the file. Both methods select among the three maps.

    • 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 file will the tool accept?

    Only a 512 KB stock bench or boot read. A 1 MB file with eight codeblocks is rejected. If the file already has one or two codeblocks, the patch still produces three switchable maps. A sample read is on CloudFront.

    Does the immobilizer have to be on?

    Yes, at least in the EEPROM. The VIN must show on the VCDS engine page. Turning immo off in the flash while leaving it on in the EEPROM is described on ECU Connections. If VCDS does not show a VIN, contact support before you pay. The wrong VIN or the wrong soft coding is not refunded.

    Can you tune the file after the patch?

    Yes. Open the patched file in WinOLS as a version of the stock file. Loading it as a new project uses the wrong checksum and can brick the ECU. Take a full ECU backup before you flash.

    The original EDC15 write-up is on the Bosch EDC15 MapSwitch post. How the slots work is on the mapswitch page. MED9 uses the MED9.1 tool. Both families are listed on the multimap hub.
