Calibrated for pump fuel (95 RON / 91 Octane). Features conservative timing and linear boost for fuel economy. Race / High Octane
This is not a standard "Stage 1" file. It requires custom definition files (OLS or XDF) created by specialized calibration engineers.
This is made possible by the vkKraQu variable. On a standard, unmodified MED91 ECU, vkKraQu might be fixed, forcing the engine to always use the same maps, such as LDRXN_0_A , KFZW_0_A , and others. However, by modifying the ECU's software, tuners can program it to change the value of vkKraQu based on a specific driver input, such as pressing a button on the cruise control stalk. When vkKraQu is set to "1" (e.g., cruise control active), the ECU will use a different set of maps, such as LDRXN_1_A , effectively switching to an entirely new engine performance profile. This allows the engine to instantly adapt to different driving conditions or fuel types without needing to reflash the ECU. med91 multimap

🚀 Unlock Your VAG MED9.1 Potential: Multimap Switching Now Available! Calibrated for pump fuel (95 RON / 91 Octane)
At its core, the is not a single map but a robust framework for integrating, overlaying, and synchronizing multiple map projections and data layers within a single interface. The "Med91" designation typically refers to a specific version or a proprietary standard developed for high-fidelity medical, logistical, or environmental mapping (depending on the context—most notably used in telemedicine logistics and disaster response). The "Multimap" feature allows users to view the same geographical area through different lenses: satellite, topographic, street-level, and thematic heatmaps, all tiled seamlessly.
By exploring the capabilities and benefits of Med91 Multimap, organizations can unlock new opportunities for data-driven growth and innovation. As the platform continues to evolve, it will be exciting to see how Med91 Multimap shapes the future of data integration and management. It requires custom definition files (OLS or XDF)
: Let go of the controls to lock the selection. The setting saves to the non-volatile memory and remains active across future drive cycles.
Tools like the open-source EliasTuning MED9.1 Multimap Tool on GitHub automate this process. The utility uses YAML-defined patch configurations to look up specific VAG part numbers and software versions. It executes assembly insertions that bypass the factory load regulation maps.
