Multimap: Med91

This is not a standard "Stage 1" file. It requires custom definition files (OLS or XDF) created by specialized calibration engineers.

The "91" in the name often signifies a connection to emergency codes (akin to 911) or a specific military grid reference system iteration. The "MultiMap" functionality refers to the ability to toggle between, or blend, various mapping engines simultaneously—raster tiles (satellite imagery), vector tiles (street maps), topographic contours, and even heatmaps of incident density. med91 multimap

At its core, a "multimap" is a sophisticated feature that allows an ECU to host and access multiple distinct performance "maps" (or tunes). A standard ECU remap overwrites the factory settings with a single, new configuration. In contrast, a multimap injects several different calibrations into the ECU's memory, all of which are ready to be used. The driver can then switch between these different tunes while driving, adapting the vehicle's power delivery and characteristics to suit different driving conditions, fuel types, or desired levels of performance.

Many enterprise GIS solutions (like ArcGIS or QGIS) are powerful but slow. They require specialists to operate. The Med91 MultiMap bridges the gap between a heavy GIS desktop application and a lightweight mobile viewer. The "MultiMap" functionality refers to the ability to
