Using the "Set" or "Res" buttons on the stalk to cycle through profiles.

Modifying your vehicle’s ECU may void warranties, violate emissions laws, and cause engine damage if done incorrectly. Always tune responsibly and on a dyno. The author assumes no liability for any damage resulting from the use of this information. edc15 multimap

Unlike a standard tune, which overwrites the original maps with a single performance file, a Multimap setup allows the driver to toggle between, for example: Using the "Set" or "Res" buttons on the

The EDC15 uses an external flash chip (typically 29F400 or 29F800 series, 512KB or 1MB). A standard tune occupies a single memory block containing all maps. The Multimap hack exploits unused areas of this flash—often the upper half of a 1MB chip, or compacted storage in a 512KB chip after optimization—to host a second or third complete map set.

: Implementing multimap requires deep reverse engineering of the EDC15 binary. Developers identify free space in the ECU’s memory to inject custom assembly code that intercepts standard routines.

Here is everything you need to know about why you want it, how it works, and how to get it. Why Even Bother with Multimap?

. He realized that the EDC15 used "coding blocks" for different transmission types (manual vs. automatic). By "tricking" the ECU into thinking the car had changed its transmission type on the fly, he could force it to jump between different sets of maps.
